Slussen in Stockholm by BIG and NOD
00/00/0000, 00:00 | David Report
The collaboration between BIG Architects of Copenhagen, Denmark, and NOD Landscape Architects of Stockholm, Sweden, provides not only a solution to Slussen, one of Scandinavia’s busiest intersections but most importantly privileges the pedestrian and cyclist.
When the Stockholm City Council invited BIG and NOD to act as design consultants on Slussen, the direction given was to create a proposal that reconnects the historic Gamla Stan with Södermalm. Understanding the long legacy of previous attempts to solve Slussen’s traffic chaos, the team set out to create a single form within which the different modes of traffic are layered. The proposal touches the waters surrounding Gamla Stan and slowly terrace up using ascending and descending ramps to create a new, coherent area focusing on providing an attractive and functional setting for both movement and rest.
Currently considered inaccessible to pedestrians and cyclists, Slussen is a black hole in the heart of Stockholm. It is no wonder then that Danish-Swedish collaboration has made sure to offer cyclists as well as pedestrians easy access to and through the area. The proposal turns Slussen into an urban recreational area assuring easy movement for the citizens and tourists of Stockholm. Slussen will gain a whole new kind of urban space unlike any other in the world, where artwork, a summer’s midnight stroll and outdoor theatre can cohabitate with the need to move cars, buses, trains, metro, and boats. The strength of Slussen lies in its continual and varied movement which the proposed ramped landscape only underscores. The heavy traffic of cars and buses is carefully immersed under the rising hillside. Suddenly due to the submersed traffic, large areas have been freed and are made attractive to the entire city to enjoy. As a result, new opportunities for urban life are created.
The basic traffic system has already been developed by Nyrens Arkitektkontor as part of an architectural competition, with soft traffic and a public program on the top and with heavy traffic at ground floor level, storing away boats, buses, metro, cars and trains. But instead of separating the different levels, connected only by stairs and elevators in a traditional way, we propose to integrate all public, accessible areas around Slussen by interweaving the levels using descending and ascending ramps as this will allow people to move freely between the levels.
Pedestrian zones are designed to connect the already existing promenades and road crossings, and all areas of the new Slussen are as such accessible to pedestrians. The bicycle lanes follow the road as well as the promenade along the waterfront, and are pulled away only where the curvy bays of the new Slussen are created to leave space for pedestrians to enjoy the waterfront.
Today Slussen does not take advantage of its rising topography. Seeking to utilize its unique setting the proposal uses the terraced hillside to house kiosks, shops, and tourist information stands accessible through the network of ramps. In this way, a new and active urban area is created. In addition to the landscaped contours and pathways characterising BIG and NOD’s proposal, the dispersion of light has been instrumental in developing the site and the various levels. By day, natural light will pierce through circle shaped skylights into the lower levels. By night, the skylights will be illuminated from below. The expression will thus vary from dusk till dawn, from season to season and depending on the weather. This dynamic process and the continual hum of traffic will serve as the backdrop to a new urban form and regenerate life into the surrounding neighbourhoods.
There is an animation showing the complete program as well. I will put it up in a separate post as well.

introducing a new design: Hus1
00/00/0000, 00:00 | LamiDesign Modern House Plan Blog
The result of my year long study of the Swedish housing industry, and my love of mid-century modernism, the Hus1 puts these influences together with practicality and livability of the many small 50s and 60s homes in my own neighborhood. The basic two bedroom house will start out at modest 1,350 sqft, or the larger 1,750 sqft 3 bedroom plan shown below. Both have the option of an additional 500 sqft master bedroom upstairs which in the larger plan allows the downstairs master to serve as a family room.
A very livable home, the L shape creates privacy for its rear terrace where family life can flow out from the living areas. Conventional construction makes this house easy to build, and the iconic traditional form won't scare the average home builder.
Look for Design Prints to come available on the site soon. Well, you will hear about it here when it happens! And yes, this is the house for which we have been experimenting with new drawing styles. Not quite sorted out yet, but when its done the new collection will have a distinct graphic look apart from the original collection of designs.

Recycled Houses
00/00/0000, 00:00 | Green Home Building and Sustainable ArchitectureA big truck tractor was towing this entire 1200 square foot house balanced on two huge steel I-beams and a bunch of wheeled dollies. Progress was slow but steady as it inexorably moved toward its next incarnation. Just that morning it had departed its original home where it had been seasonal housing for migrant workers.
The owners of this seeming mirage had searched for just the right orphaned house to adopt as their own, lovingly place it on a new foundation, and refurbish it. Many houses would not be suitable for such a trip; generally only well-built wooden structures can withstand the stress of such a move. This house had all the qualities they were looking for: charm, integrity, and affordability. The entire cost of the house and having it moved was $10,000.
By the time they have it completely fixed up with new plumbing and electric service, an insulated stucco exterior, new energy-efficient windows, a metal roof, a completely rebuilt front porch, all of the interior walls resurfaced, and miscellaneous repairs, they estimate that the total cost of the project will be about $50,000, including the land. Not bad for what in most regards will be as good as new!
Of course new is not what they wanted; they bought this early twentieth century house (it's actual date of construction is unknown) precisely because of its special vintage quality. It reminds one of the owners of the house his grandmother lived in, with 9 foot ceilings, three smallish bedrooms, tongue and grooved fir flooring, cast-iron radiators, built-in cabinets, drawers and even ironing board, and the intangible quality of a by-gone era. They plan to retain the original floor plan intact, only altering a walk-in closet to become the mechanical room and turning a room off the kitchen into a dining space.
The house made the entire trip with just a few places where the plaster cracked in one corner, which is easily repaired. This is one very solidly-built house, made from the sort of fir that no longer can be bought. There was only one place under the kitchen sink that had suffered leak-induced rot over many years; everything else is as straight and true as any carpenter would want.
Another late twentieth century vintage home of about 800 square feet came from property leased from the Federal government and the house needed to be moved. With local help, the buyer of this little home added an additional room onto the original to comply with the homeowners' association square foot minimum. She has thoroughly enjoyed the process of remaking this simple cabin into her charming home, imbued with the wonderful quirky qualities that spring from her fanciful mind.
Once a house is moved it must comply with current plumbing and electrical codes, so these elements were completely redone. Most of the windows were replaced with second hand units that gave her just the views that she wanted. The exterior was resurfaced with rough-sawn lap siding and a new metal roof was installed. The original interior plastic paneling was replaced with sheetrock, and decorated with lots of natural wood trim. The whole feeling of the place is one of lovingly crafted touches wherever the eye lands. The new owner says, “I would much rather live in something recycled than buying something brand new which has no character. I let this house come together…it just evolved!”
Creating new life for old or abandoned houses has got be one of the most sustainable ways of making habitation. This is the ultimate form of recycling, where most of the basic components of a house are utilized intact instead of being tossed into a landfill or burned. There is a tremendous savings in the embodied energy of the house (in both materials and labor), so that all that needs to be done is to repair and polish the original dwelling to create a whole new life for it. Hoorah for these people who have the vision and willingness to take on these projects!
The Enertia House
00/00/0000, 00:00 | Green Home Building and Sustainable ArchitectureThe Mother Earth News editor said that these homes had been featured in their magazine before. They essentially provide two wooden shells for the home, one inside the other. She said that there was no mention in the article about the cost per square foot. She was wondering what I thought about the concept from the standpoint of sustainable architecture.
Here is my response:
Double envelope house designs have been around for several decades and they definitely offer some benefits, as well as raise some questions. Any house that takes advantage of the geothermal properties of the ground will be doing its inhabitants and the earth a good turn. This can take the form of earth-sheltering in general, or some clever system of circulating air like the Enertia concept; coupled with sensible passive solar design, it is possible to approach a "zero energy" home.
The concerns about their system that I have are: The use of wood as the primary building material is not generally sustainable in this day of lost forests. With the double envelope design, you are practically building two houses to end up with one. Relying on wood as a thermal mass material compromises the potential thermal performance because wood does not serve this function nearly as well as traditional masonry thermal mass materials. So, I guess what I am saying is that a more sustainable and less costly design can be accomplished in more traditional ways.
Clark Snell of www.thinkgreenbuilding.com wrote, "I spent five minutes looking over the web site, so these comments are only based at looking at marketing materials, i.e. they may be inaccurate. Ditto what has been said so far. A couple more “red flags:”
- Solid wood envelope. They seem to be using the old “mass enhanced R-value” argument for why solid wood walls perform well thermally. I think it’s well established that this is true only in very specific climatic situations. Touting solid southern yellow pine walls in comparison to solid white pine walls is like saying a Chevy Suburban gets better gas mileage than a Hummer…that’s not really a useful statistic.
- Energy without oil. The presentation intimates that this is a completely passive design. For example, no heating system is mentioned. That simply isn’t credible for most climates using the technology they are describing.
- Passive means local. You simply can’t create a design that relies heavily on passive techniques and generalize it across climates. In my area where we have high humidity, I’d wonder about this convective loop through the attic and basement, for example.
I could go on. I’m a passive design freak, so I’m all for the basic concepts they are dealing with. However, I don’t see anything really new here, but see marketing claims touting what they are doing as a major breakthrough and “the answer”. That always makes me nervous."
David Eisenberg, of www.dcat.net wrote, "After a skimming around their website, I see that they sell kits and their base prices don't include a lot of things - some of which are enumerated:
That's a pricey list of not includeds and notice they say nothing here and I saw nothing in my quick scan of the site about some really big and typical costs like excavation and foundations, below grade walls, or basement floor. They say this is a structural package but they don't mention all the things that are going to be extra that most people would expect in a house - plumbing, wiring, fixtures (electrical and plumbing), stove, etc. and especially that the solar PV and thermal water heating systems are not part of the package. It would be nice if they said right up front and clearly what they do and don't sell. And they should make it very clear that all the prices include only the factory labor, not the cost of actually assembling and finishing these structures.
But the biggest issue I have is that these are essentially double wall structures using an enormous amount of thick, milled lumber, which appears to use many times more wood than goes into a stick frame house. It would be interesting to see if they use more wood than a comparable log home. They'll likely be more energy efficient than a log home, but they'll use as much or more wood. Which raises all sorts of issues about the sustainability of this venture - beyond just the trees cut down - much bigger transportation, milling, probably kiln drying impacts as well. The concept is fine and likely works reasonably well in most climates. I'd need to see much more actual performance data and of course real cost data to be able to make any kind of realistic judgment of the viability of this concept as anything more than a niche market system. But between the costs which are going to be very high and the amount of materials going into one of these, calling it sustainable seems like a real stretch."
And finally, Jeff Judkoff of the National Renewable Energy Laboratory, wrote: "The concept of "Double Envelope" homes has been around since at least the 1970's. A number of them were built in the late 70's early 80's. Some variations of the concept were published in the Solar Home Book, by Bruce Anderson and Michael Riordan in 1976, Cheshire Books. Other publications in that time frame also showed the concept. The only truly new concept here is the notion that the resins in the wood behave as phase change storage materials. I have no idea if that is true, but I doubt it because the most common phase change is from a solid to a liquid, in which case the resins in their liquid phase would leak out creating a mess. That's not to rule out the possibility that some tree resins could go from a solid to semi-solid phase, or that they are encapsulated in the wood, I just don't know if they can, and would only be able to determine it through controlled scientific testing in a calorimetry chamber. Phase change storage can really be a big boost to the performance of many flavors of passively heated and cooled homes.
There are many ways to acheive highly efficient homes that more or less "heat and cool" themselves. Different approaches have different costs and will work better in some climates than in others. In Colorado, my lab, NREL, worked with Habitat for Humanity to create a net energy producing home. We used super insulation, passive solar tempering, ventilation heat recovery, engineered shading, solar hot water with a backup instantaneous water heater, compact flourescent lighting, and PV. We also have more than a years worth of detailed data to prove the performance of the home (it really was a net energy producer for the last year).
I saw no data to indicate how well the Enertia home actually performed from an energy perspective. Cost, energy performance, and comfort are the key criteria by which to evaluate such homes, and data is always better than arm waving, or catchy theories. Nothing beats the scientific method for objectively determining the value of an idea."

MODERN Challenge: Dual-purpose design in single-room space.
When it comes to having an office / den that can also accommodate home visitors, there seems to be limited choices in comfort and style at an affordable value.
I'm working with a lovely couple of young professionals who have requested additional seating that can easily be converted into a bed in their office. When not being used as a guest room, the sofa bed could provide a place to sit down for casual business conversation while the other is sitting at the desk.
From what I’ve discovered, most pull-out sofa beds are rather uncomfortable. I also find it hard to convince a client to invest in a piece of furniture that is more gimmicky than functional. I always say that if you are choosing to add furniture to your collection, go for comfort and timeless style in small spaces.
MODERN Solution: Chaises and day beds that are classic, timeless, multi-functional (without the gimmicks), and most importantly – comfortable!

Architecture & Interiors by: SPLYCE
Location: Vancouver, Canada
Specialty: residential and commercial renovations to custom furniture and landscapes
Project Highlights: Renovations of West2nd and West 7th private residences
Interior Photography: Michael Boland Photography
The great thing about blogging is that I have gained such a great sense of community, meeting so many amazing talents from all corners of the world and also reconnecting with the local design scene. Earlier this year I was honoured to read a kind comment from one of Vancouver's most talented architects, Nigel Parish of SPLYCE. I came across his work last year while sourcing images for modern west coast architecture. Over the past months, I have been lucky enough to learn more about Nigel's work and approach to both architecture and interiors. You can see through his work the merging of the structure and interior volumes of space holds a strong relationship and is seamless. I admire his keen sense of attention to construction details in exploring natural materials in flush exterior cladding and the combining of economical yet quality materials.
Here is an example of his work shown in the West 2nd renovation project on a 1,200 sq.ft. 1950s apartment. Love the detailing of the hardware and open staircase using laminated glass treads. Another favorite of mine is the West 7th Penthouse renovation, where his attention to details is well executed through the design of a multi-functional built-in that cleverly includes a movable cantilevered worktop.
His bio reads "The fascination with craft and how things are made is reflected in all of Nigel's work by an acute attention to detail on every scale. From the broader conceptual organization of spaces to the finer detailing and selection of finishes, Nigel strives to apply meaning and purpose to all design elements. Design decisions based on the specific and unique parameters of each project, such as site conditions, budget constraints and client's wishes, always take precedent over style and popular trends. The results are objects and spaces infused with meaning and lasting beauty." - this is well represented in his work. Stay tuned for the soon to come feature magazine articles on his recently completed home renovations in West Vancouver. Excellent examples of icon additions to Vancouver's collection of modern westcoast homes.

745 Navy For Sale [sigh]
00/00/0000, 00:00 | FUTURE HOUSE NOWThe luscious 745 Navy is on the market. Here are a few pics from the real estate site Curbed LA, and a few more from The Value of Architecture - Los Angeles, a site that showcases architectural properties with the goal of raising awareness of the value of good design. For the best pics, though, check out this excellent slide show from Bulldog Realtors.
745 Navy is a bright and breezy little bungalow of just 700 square feet. It's clean and casual. Just look at that translucent wall! Amazing! I just love that. I also like the concrete floors, the funky carpet treatment in the bedroom, and the fact that it's a remodel of an existing home. It's the kind of place I can easily imagine myself living in.
However, it's not quite the kind of place I can imagine my wife and two kids living in with me, although apparently there's an existing, approved plan for a two-story addition! But for now I think I'll just have to be impressed with it's sunny, groovy design and store away a few ideas for another day.

Cool Modern Homes from Bark Design
00/00/0000, 00:00 | FUTURE HOUSE NOWDoris is the work of Bark Design, a firm with a modern bent that FHN reader Mike was kind enough to point out (thanks again, Mike!). Doris is swell gal, with lots of attractive features. In particular, I adore her flat roof, her expansive banks of windows - and she's got a carport! Oh, I really like carports.
Doris also has a wonderful floor plan with possibly the greatest kitchen in the world - made so by the overhead door out to the patio. It incorporates a screen that can be rolled down when the door is up to keep bugs out while letting breezes flow. Perfecto! My wife would love that.
Doris has a brother, Boris, and a good friend in Leroy G. Cooper.
Here are a few pics Bark shared with me of the Burbank, another model that isn't shown on their site yet. I really like the window placement on this house - it looks like it has pretty good solar orientation.
I must say, I find a whole lot to like aesthetically about Bark's homes. There's definitely a signature style with the flat roofs, carports, window arrangements and the way outdoor living spaces are approached. But what I like most is their attitude and approach to bringing modern homes to the market. I e-mailed Bark, and was very impressed with what they had to say about their direction.
"We are a team consisting of a developer, architect, and
contractor who were getting frustrated by the dismissive response to
modern design by clients and real estate professionals in our area,
so we decided to do our own thing with incredibly positive results.
We couldn't understand why people would seek out the latest design
and technology in cars, electronics, etc., but new builder/spec. home
construction seemed to be stuck in the year 1900. How many people
would go to a store for a new computer and happily walk out with a
univac the size of a refrigerator that only did addition and
subtraction? Yet people were making a similar decision every day with
a new home. We just didn't get it.
So, we design and build homes that respond and complement modern
life, are extremely efficient in terms of energy, space, livability,
constructability, and are affordable."
I've had exactly those same thoughts for a long time. I like what Bark is doing, and they must be hitting the mark - they have seven projects "on the board" for 2008!
Very exciting!

Paint-free shirt design from Viidrio
00/00/0000, 00:00 | David Report
The idea behind Viidrio shirt designs is to practice other options aside from screen-printing. Initially when they knew they wanted to use an aluminum tin, they were thinking about having the containers printed by packaging manufacturer. But that option would have contradicted the concept behind Viidrio.
The shirt designs have embroidery-art, and Viidrio wanted the packaging to have a cohesive design and theme. Packaging to Viidrio has a big impact on how you perceive a product at the beginning, and at the end of its use. Packaging becomes part of the product, and is a form of presentation. But it must be done correctly, the same way someone can plate a meal attractively, for one to be excited about what they are just about to eat.
The top of the tin has an embroidered design that foreshadows the design that is in the shirt. The recycled paper band that is wrapper around the tin (that contains additional graphics and product identity) is sewn together at the ends. The band around the tin is also affixed with clear stickers for easy removal.
The materials of the Viidrio shirts are 100% cotton threads, aluminum tin, 100% recycled printed matter and aluminum foil tape.
The other main concerned about packaging is the waste it produces. With this particular shirt packaging, the paper used for the band is 100% recycled paper from grocery bags (therefore making a 3rd cycle of use). After removing the band (if the consumer wishes) the tin can be reused to store any small non-perishable item. Example: jewelry, loose change, keys, paper clips, etc. If you ultimately don’t want the container, you can always take it to a recycling center. Last, but not least, you can return 5 undamaged containers to Viidrio. In exchange of a free t-shirt of your choice.

00/00/0000, 00:00 | :: Vol. 2: the design management weblog | by ralf beuker :Pugh + Scarpa Atchitects | Solar Umbrella
00/00/0000, 00:00 | Modern Residential Design
Model Rebuild - When remodelling their own residence Angela Brooks and Lawrence Scarpa could never have imagined the press and accolades that would be bestowed upon a build designed around their own very personal needs. Economical, solar powered, solar water heating, nearly off the power grid and with a fitting yet aesthetically contrasting extension. A rear extension that embraces the house's 1920's bungalow origins and pays homage to its design sake, the Paul Rudolph Umbrella House of 1953.
Name of Project: Solar Umbrella, Venice, California, USA Information courtesy of: Pugh + Scarpa Architects
Overview and Plot
The lot, in Venice California, typical of the area, has two road frontages. This allowed the house's orientation to be flipped, the crux of this build. With the living area and kitchen behind now facing the larger rear garden, an additional bedroom was added upstairs, and the second bedroom converted to an office. Most of all, the flip orients the house to the southern sun allowing the sun's energy to be stored in the concrete eastern and western walls and floor. 
Design
The extension has the majority of its glazing along the warmth facing southern wall, with northern glazing opening up for cross ventilation. The architects describe it as "global regionalism," Californian indoor outdoor flow, wrapped in modern technology using recycled and sustainable materials, offsetting the use of concrete with gains made through its thermal storing properties that lead to lower power bills. Overhangs regulate the sun in its strongest months and double glazing with a low-E film , framed in aluminium with thermal breaks, control the wind and indoor environment. To save on materials the solar panels themselves form the outer canopy and Solar Umbrella, shading the house. With the rear set up, insulation was blown into the walls and floors of the original wing and operable skylights in the kitchen and bathroom provide natural light and ventilation whilst maintaining privacy.
Upstairs
In winter, warmth is provided through radiant in-floor heating powered partly by one of three solar hot water panels. Two are used to pre-heat the domestic hot water before it gets to the gas-fired hot water heater and the other to heat the pool. These panels halved the gas use of the house which is now 2.5 times as big! As usual there was initial outlay for the solar water heaters and panels, which 10 years.
Living area extension
Although the double height extension sets the house apart from its neighbours, the fact that it is at the rear facing the alley, contrary to most of the houses on the block, mean its northern facing traditional façade, lets it fit in with the Joneses. The services are concealed up the side of the house, and a bike rack just inside the new front gate provides mobility to the nearby shops (apparently a novelty in the US).
Exterior
Well thought out landscaping incorporates gravel, to allow the plot to drain and prevent it from heating up like large paved areas do, and planting is drought tolerant, with species that appeal to the abundant hummingbirds in the area. The new pond and pool also help regulate the temperate and composting was also included as part of the landscape design.
Layout
A relatively simple layout provides for both open plan living and more intimate work and rest areas.
Downstairs the office, with access to the main street, sits beside the second bedroom and main bathroom on the eastern wall. The living room and kitchen take the southern and western walls respectively. As well as allowing heat to rise up and out the upstairs windows, the industrial like steel stairs link the downstairs area to the more private master bedroom with en-suite.
The Results
The house now provides an additional open plan living area ideal for the couple's son, connecting outdoor play and space indoors. The Solar Umbrella plays its dual role, keeping the house cool and shaded in summer and warm through its solar panel composition in winter. Utilitarian, the house is built to be lived in and enjoyed rather than as a show-piece 'typical' modern build. This to me is what makes this a home.

David Hertz - Studio EA | McKinley Residence
00/00/0000, 00:00 | Modern Residential Design
Green Alchemist's Residential Compound - The McKinley Residence is David Hertz's live in laboratory for modern - environmentally friendly - residential design. Converting common elements into green design, it's feature packed. The house is a true testament to David's commitment to the cause and to top it off forms a homely modern residence, showcasing practical design elements, fine tailored for a young family.
Aimed at "spreading the word", the Studio of Environmental Architecture is David Hertz's latest venture, leading the way in Eco friendly design and sharing what he's learnt both through his residential work and his own house. Many thanks to the team at Studio EA for the details on this house.
Overview
Designed as a new house when Venice was till a rough neighbourhood the house presents a relatively strong/protective façade at street level and uses enclosed balconies to extend the upper levels and take full advantage of sea breezes.
The house consisted of two pavilions connected by a bridge, and was already cutting edge (environmentally) through its use of Syndecrete®, which contains about 41% percent recycled content and is twice as light, with twice the compressive strength, of normal concrete. Syndecrete® is David's own development and one of many featured in the residence.
It is now a compound made up of four discrete two-story buildings linked by three enclosed bridges that all face onto the courtyard.
Style "Balinese Modern"
Working it through
There was only one snag in the whole process. David is staunchly in favour of green design, the mere fact of adding that much space nagged at him. "There's no getting around the fact," he says, "that on a purely ecological level, 4,400 square feet is a lot of house by most of the world's standards."
His solution was to make the house the greenest house of its size he'd ever seen. Hertz used this house as a case study for green building techniques. An array of 20 solar collector panels on the roof help generate about 70 percent of the home’s electricity needs, and other sections of the roof are given over to flat-plate collectors that provide hot water to the water heater, which then sends it into a radiant heating system in the concrete floors.
I've no beef with the results, David's family expanded and so has his residence, the house is all used and as much as we battle with the urges, who wouldn't want their own compound like this. David's innovative materials and willingness to push for a more environmentally sound house is exemplary.
The materials used were chosen carefully to support environmental sustainability and the design intent. Recycled and FSC certified sustainable woods such as Ipe, Mahogany, and Fir, are used throughout the house to complement the Syndecrete®.
The Syndecrete® acts inside the house as a kind of “solar sink” for passive solar energy transfer, storing up the sun’s warmth during the day, and thus keeping it from overheating the interior, and then slowly releasing that heat during the night. Syndecrete® flooring was chosen for several reasons; it eliminates mold and dust caused by carpet, requires less maintenance, and is more environmentally sensitive than carpet, wood, or other floor finishes.
In order to maintain excellent indoor air quality, David used zero VOC paint, and eliminated a forced air system and carpeted floors, and with them mould and dust.
Another bonus of these materials is the resultant durability and functionality of the house. Its for living in. Rather than begin a minimalist box (don't get me wrong they have their place) the house portrays both David's design innovations, but also the family's efforts, endeavours, favourite drawings, posters, toys, etc. And it's a tough house.
You can see here one of my favourite shots showing the utilitarian nature of the house, and how its designed for a family.
Yup, David's hosing it down, an ability that's now on the list for my house. You can also see that playful design feature to let the kids feel its their house too, a pint size door for them.
Green Credentials
Hopefully in the images, you'll spot some of these fantastic features.
- Passive Ventilation – eliminating the need for a forced air system the shaded front living area naturally ducts cool air up thought the house and stairwell, then out the temperature sensitive skylights.
- Solar Energy – an array of 20 solar panels on the roof supply around 70% of the home's energy needs
- Photovoltaic Panels and Flat Plate Collectors – providing hot water to the water heater and subsequently the radiant heating system in the concrete floors. David says to heat the place, with these panels installed takes about as much energy as a 60w light bulb, all taken from his solar array.
- Vacuum tubing on the roof, which uses a parabolic collector to focus the sun’s rays, provides additional hot water
- Recycled FSC certified sustainable woods such as Ipe, Mahogany and Fir
- That Syndecrete®, a light-weight concrete that uses 41% recycled content - it also holds various pigments and textures to form furniture throughout the house, like the kitchen bench, table and bathroom sinks.
- Zero VOC paints
- High performance heat-mirror glazing
- The pool system uses an ionization and silver filter, eliminating the need for chlorine
Layout
I've wanted to write about David's work for some time now as his preferred layout for houses draws from tropical bungalows and linked pavilions.
Phase-1
You'll note that he has separated the functional areas of the original house at the bottom, both vertically and horizontally into 4 boxes. The living and dining come entertaining areas at the front are split from the garage at the rear to form an external lounge/fire pit, one that tops my list for "ideal after work summer beer spot".
Above, the bedrooms retreats, with the master bedroom above the lounge, and the children's bedrooms, back away over the garage.
Second only to the fire pit, is the outdoor sleeping area off the master bedroom. In summer time, the enclosed balcony becomes a comfy, cool sleeping area.
Phase-2
This renders the children's original bedrooms as guest areas that convert into a large rumpus room for rainy days. To accommodate the three children as they grow older, David's given them more space (between them and their wing of the house) and space for their guests. They have a bedroom and studio area in the upstairs of the new wing, and mum and dad gain an open plan kitchen/dining area with a wall that opens up completely to the pool and inner courtyard formed between the two wings.
Results
This building is a successful study in architecture that is both aesthetically pleasing and environmentally responsible, whilst functioning as a pair of Levi 501s, hard wearing, sexy and a design classic.

Historic Gastown is now the home to an A-list of must sees from a cool hip shop for modern mom and pops, visit Modern Kid which offers kid-friendly "easy on the eye" design for the modern novelist while fashion fronts like Obakki (tops as my favorite fashion retail interior for Vancouver) or Hunt & Gather bring a unique collection of one of a kind pieces made right in the store by costume designer atelier.
Images of Obakki above are through my eyes. Some of my favorite details include exposed concrete walls meeting seamlessly with polished concrete floors. The extension of corian meeting reclaimed fir to reverse beveled drywall details lit from behind to give a diffused wash of light to highlight the exposed brick walls. Love, love the architectural detailing. The interior reflects the quality and craftsmanship of the Obakki label right down to each detail.

Natural Building Network
00/00/0000, 00:00 | Green Home Building and Sustainable ArchitectureThe Natural Building Network is a non-profit membership association, where the joining members can place listings for their services and talents and network world-wide. Towards this end, there are directories of natural builders by location, by specialty, and by their willingness to teach others their skills. This helps the members find suitable employment and helps the public find experienced builders who live in their area. Additionally there are classified listings of announcements about related matters. The Network website also features listings of workshops and events around the world, along with resources for further education.
This network and website offer a much-needed central facility for collecting information about natural builders around the world.
California's Green Building Code
00/00/0000, 00:00 | Green Home Building and Sustainable ArchitectureThese new codes include basic passive solar mandates: "When site and location permit, orient the building with the long sides facing north and south. Provide exterior shade for south-facing windows during the peak cooling season. Provide vertical shading against direct solar gain and glare due to low altitude sun angles for east- and west-facing windows."
For renewable energy, the codes says, "Use on-site renewable energy sources such as solar, wind, geothermal, low-impact hydro, biomass and bio-gas for at least 1% of the electric power."
For water conservation, the code says, "A schedule of plumbing fixtures and fixture fittings will reduce the overall use of potable water within the building by 20%, and provide water efficient landscape irrigation design that reduces by 50% the use of potable water beyond the initial requirements for plant installation and establishment."
"Each building shall further reduce the generation of wastewater by one of the following methods: The installation of water-conserving fixtures (water closets, urinals) or utilizing non-potable water systems (captured rainwater, graywater, and municipally treated wastewater
(recycled water)."
For materials to be specified for construction, the following is mandated:
- Select building materials or products for permanent installation on the project that have been harvested or manufactured in California or within 500 miles of the project site.
- Select bio-based building materials and products made from solid wood, engineered wood, bamboo, wool, cotton, cork, straw, natural fibers, products made from crops (soy-based, corn-based) and other bio-based materials with at least 50% bio-based content.
- Employ wood-based materials and products comprising at least 50% of a major building component, such as framing, flooring, or millwork, which are certified by one of five listed sustainably harvested certification programs.
- Use materials made from plants harvested within a ten-year cycle for at least 2.5% of total materials value, based on estimated cost.
- Use salvaged, refurbished, refinished, or reused materials for a minimum of 5% of the total value, based on estimated cost of materials on the project.
- Use materials, equivalent in performance to virgin materials, with post-consumer or preconsumer recycled content value (RCV) for a minimum of 10% of the total value, based on estimated cost of materials on the project.
- Use cement and concrete made with recycled products, fly ash, raw or calcined natural pozzolan, blast furnace slag (as a lightweight aggregate) .
- Select materials for longevity and minimal deterioration under conditions of use.
- Select materials that require little, if any, finishing.
- Select materials that can be re-used or recycled at the end of their service life in the project.
- Select materials assemblies based on life cycle assessment of their embodied energy and/or green house gas emission potentials.
Environmental and health-related items establish specific limits on VOC emission of materials used within the structure, as well as regulate ventilation, CO2 emissions, tobacco smoke, lighting, outside views, and noise transmission.
Additional recommended measures include:
- If feasible, disassemble existing buildings instead of demolishing to allow reuse or recycling of building materials.
- Utilize a Frost-Protected Shallow Foundation.
- Use pre-manufactured floor and roof systems to eliminate solid sawn lumber whenever possible.
I have been advocating most of these measures at www.greenhomebuilding.com for many years now, and it is heartening to see them being officially sanctioned. This is a far-reaching and well-considered attempt by California legislators to establish requisites for living sustainably. If there are going to be building codes, they might as well be green! Yeah California!
Strawboard Panels
00/00/0000, 00:00 | Green Home Building and Sustainable Architecture
Strawboard building panels are a kind of structural insulated panel (SIP) designed to replace 2x4 stud and drywall construction for both interior and exterior walls, as well as provide load and non-bearing ceilings, roofing, doors, flooring, and prefabricated buildings. These environmental friendly, solid panels are made of all natural fibrous raw materials, mainly wheat and rice straw. The durable panels feature thermal and acoustic insulation as well as fire and termite resistance and are available for a variety of applications to speed up the construction processes. While these have been used in over 20 countries for more than 50 years, strawboard panels have only been introduced to the U.S. in the past few years.
Strawboard panels have a solid core of compressed wheat or rice straw. High pressure and temperatures forces the straw to release a natural resin that binds the fibers together. The compressed panels are then covered with either paper liners or OSB that is adhered to both sides with water based non-toxic glue. The standard panel measures 4 feet by 8 feet by 2-1/4 inches to 8 inches, weighing from 140 lbs. to 440 lbs. each. Custom panel sizes are available ranging from 3 feet to 12 feet long.
The panel's high density and low oxygen content does not support combustion. Since the panels do not contain added resins, alcohol, or other chemicals, no flammable vapors are produced. The panels have an R-value of between 3 and 25, depending on the composition and thickness. For permanent protection against insects and fungal decay and additional fire resistance, the boron compound polybor can be factory added to the core.
The product's workability is similar to wood as it can be sawn, drilled, routed, nailed, screwed, and glued. Lightweight wall attachments such as shelf brackets, picture frames, mirrors, and towel bars can be attached directly to the panel.
Since straw is a renewable by-product of wheat and rice production that becomes available annually, it takes less acreage (by about half) to build an equivalent house than with standard lumber, and which would then potentially preserve that forest for ecological habitat and CO2 sequestration.

The Billboard Earthbag Project
00/00/0000, 00:00 | Green Home Building and Sustainable Architecture
The designers say: “Because most conventional sandbags are fabricated from polypropylene, they are very vulnerable to UV rays and quickly begin to deteriorate when exposed to the sun. Consequently, earthbag shelters need to be plastered to maintain their durability during extended use.The Billboard Earthbag Project envisions using billboard vinyl as an alternative material for earthbags. Polyvinylchloride (PVC) or vinyl, a virtually indestructible, UV-resistant material that cannot be incinerated because of the toxic gases it would emit, represents a substantial portion of the PVC in the world’s overburdened landfills. Because of its durability and imperviousness to the sun and other elements, billboard PVC is an ideal material for reuse.” “The reuse of billboard vinyl in earthbag construction mitigates the impact of global warming in two ways. Transforming this landfill-bound material into another useful product helps lessen landfill overflow worldwide. It also eliminates the need to protect earthbags from UV rays, resulting in more robust emergency shelters that can be used longer to lessen the human suffering caused by natural disasters.”
“As a visual concept, each billboard shelter stands as a symbolic gesture of sustainability. Beyond its environmental benefits, the strategy of reusing billboard vinyl visually recontextualizes the nature of billboards, which are symbols of mass consumerism and a pervasive form of visual pollu
