The World House Project - "We Can 'Grow' Buildings"
00/00/0000, 00:00 | FUTURE HOUSE NOW
"The Evolution of Home
The WHP is a multi-year, collaborative initiative led by the Institute without Boundaries (IwB) that will explore the evolution of shelter and plan for the next generation of holistic housing design. The project will build on the research concepts of IwB’s inaugural project, Massive Change, using the same method of interdisciplinary design innovation.The home is the intersection between the individual and society. On one end of the spectrum, urban sprawl and monster houses consume huge amounts of energy and pollute the atmosphere. On the other, over a billion people live in urban slums or in the streets without shelter.
The ambition of the World House Project (WHP) is to generate a system that achieves a balance between these extremes, and operates on the principles of sustainability, universality, technological responsiveness and balance, so that we may create dwellings that promote the long-term health of nature and human cultures."
They're benchmarking homes from around the world, old and new, studying them to gain an understanding of important implications of "climate, culture and terrain." The team, international and interdisciplinary in nature, will examine housing in the framework of twelve core elements of housing design and work to "create dwellings that are grounded in the principles of ecological design and that promote the long-term health of natural and human economies." The twelve core elements are: identity, social, communication, spatial, constructional, air handling, energy, water, waste, food, mobility, and finance. That's a very compelling list, indeed.
Here are a few images from the World House Project scrapbook on Flickr that I really like:
I've always imagined that homes could (and should) be built in this way!
It will be very interesting to see what comes out of this project. I'll be looking forward to watching it.

Freewheelin way to go
00/00/0000, 00:00 | David Report
The Freewheelin story.
Bike sharing was a hit when launched in Paris in 2007. It was cheap, convenient and eco-friendly. End of story? Not so fast. A U.S. health insurer changed the game and wrote a new story. Humana promotes its business agenda - lower health care costs - through a state-of-the-art bike sharing program tested during the 2008 U.S. political party conventions in Denver and St. Paul.
Freewheelin promotes its social and business agenda through communication - made possible by wireless/mobile and social networking technology. When you ride a Feewheelin bike, wireless networks track your mileage and calories burned. Social networking tools help individuals track their personal successes and, by calculating reduced carbon emmisions, their contributions to the shared health and wellness of their community and the planet.

The Enertia House
00/00/0000, 00:00 | Green Home Building and Sustainable ArchitectureI recently got a query from one of the editors of Mother Earth News regarding a news story she had read in the New York Times. The writer, David Pogue, had been a judge in a contest sponsored by by the History Channel and the National Inventors Hall of Fame titled "Modern Marvels/Invent Now." A $25,000 prize was awarded to one amoung 25,000 contestants, and the winner was the Enertia House, which was invented by engineer and former log-home architect, Michael Sykes.
The 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.
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:”
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."

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:
"Enertia Homes are sold as pre-cut, numbered kits varying in size from 1000-6000 square feet. The kit is a structural package that includes the timbers for the four exterior walls and the two interior walls (Energy WallsTM) which form the envelope, as well as the flashings, gasket, spline and fasteners to put the structure together. Also included are the beams for the upstairs floor system and the rafters for the roof structure. Doors, windows, flooring, and foam SIP roof panels are priced separately as per your blueprint and climate."

creative exchange by 5th studio
00/00/0000, 00:00 | designboom weblog, design related news, reviews and previews
creative exchange is a new shared workspace complex designed by 5th studio in cambridge, england.
the project was publicly funded and designed for the areas creative workers and innovators. the building
is designed as a studio not an office, with enough room for 14 different companies. the ground floor is
adaptable, making it suitable for meetings, exhibits and other events. the first and second floors house
the private workspaces. the architects left wide common areas on these floors to encourage cross
pollination. above all this is a working garden to further encourage interaction. the building design was
also designed for optimal sustainability, using exposed concrete for thermal mass, natural ventilation
and cooling systems and large windows for minimal need for artificial lighting.

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.

New-crete
00/00/0000, 00:00 | Green Home Building and Sustainable ArchitectureI have gotten the following information from a Canadian inventor who claims some pretty amazing attributes for a product that he calls "New-crete." While it is not yet available, it has the potential to become one an amazing manufactured technology that addresses many issues related to sustainability. See what you think:
I have a patented product of lightweight cement called new-crete. New-crete is designed to form millions of air bubbles when cured. This makes new-crete 50% lighter and stronger than regular cement and 35% lighter and stronger than lightweight cement. It is also 30%-40% cheaper than regular cement. It has an R-20 insulation value with a 9-inch thick wall. It is nontoxic and not corrosive and it floats.
Once this is up and running we can start supplying the world with better, cheaper homes. The plans for the prototype home is for a regular box style home. The next step will be to make in-ground and underground domes that are storm proof. They will also be cheaper and strong than regular homes with revolutionary designs...100% self sustainable.
The Canadian north (native reserves) are in much need for about 35 000 new homes as the old ones are in 3rd world condition.
So I know this will be better for everyone, especially the trees. This will change the world. All I need to do is find $150 000 to get it started. I see many people with lots of money (US government spending trillions on war) and the Canadian government also spending money on war ect...the will to change the world is the first key; money will then come naturally.
I believe we must start using other building materials instead of trees before they are all gone. If interested you can contact Matthew Smyth at infiniteearthdesignATyahoo.ca or visit his website: www.InfiniteEarthDesign.com

- Price: regular cement , $125 per cubic yard; new-crete, $75 per cubic yard
- It has the ability to shed water with a .5 mm saturation point. this will prevent water seeping into it and freezing causing cracking.
- The ingredients to make New-Crete are readily found around the world and are in no danger of being depleted.
- New-crete can be formed into any object. We have the designs for walls, drywall, floors, shingles, stairs, window frames, cupboards, bricks, doors ect....we can make a whole house from the bottom up using only New-Crete
- It can be painted, or laminated with wood panels, ect.
- It can be nailed into and not crack.

Natural Building Network
00/00/0000, 00:00 | Green Home Building and Sustainable ArchitectureThere is a fantastic on-line resource for all people interested in natural building: www.naturalbuildingnetwork.org. This site was initiated in 2005 by a group of people who collectively have considerable experience in the realm of natural building, which they define as "any building system which places the highest value on social and environmental sustainability. It assumes the need to minimize the environmental impact of our housing and other supporting systems while providing healthy, beautiful, comfortable and spiritually uplifting homes for everyone."
The 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.

The Billboard Earthbag Project
00/00/0000, 00:00 | Green Home Building and Sustainable ArchitectureEach year the recognize the best in environmental graphic design. This year’s Juror’s Award went to Norman Lee and Charles Houser for their Billboard Earthbag Project.
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.”

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 pollution in our world. This concept does not seek to generate imagery, but instead appropriates existing commercial imagery as a metaphor for global recycling and reuse. Assembled together into a shelter, the earthbags create a dynamic and vibrant pattern of collaged images and text from around the world, dramatically suggesting a unified, international gesture of sustainability, hope, and humanitarianism.”
According to the jurors, they "were intrigued by this project as an example of ‘cradle-to-cradle’ design pertinent to the signage industry. Utilizing intrinsic qualities of billboard PVC—UV resistant and near indestructible—this concept proposes the creation of dwellings from recycled material and imagery. The idea takes the recycling of billboards, street banners, and print graphics—already employed by art museums in the creation of second-use products—to another level. Truly inventive!"
This all sounds pretty good, and might well work if the billboard material were cut and sewn into bags. One obvious disadvantage of the idea is that since PVC is toxic when burned, this would present a potential hazard to the occupants, but of course this is true of many modern building materials. PVC poses a great risk in building fires, as it releases deadly gases long before it ignites, such as hydrogen chloride which turns to hydrochloric acid when inhaled. As it burns it releases yet more toxic dioxins. Additionally, vinyl does outgas highly toxic VOCs over time. Fortunately most of this danger would have passed with the use of recycled signs, but this could also be an issue.
Natural Building Colloquium, 2008
00/00/0000, 00:00 | Green Home Building and Sustainable Architecture
I attended the Natural Building Colloquium held this year at the Orella Ranch overlooking the Pacific Ocean near Santa Barbara, California, at the end of October. What a magnificent setting this was to spend a fine week of connecting with fellow enthusiasts of the natural building movement. About 70 attendees shared our insights, stories, passions, songs, poetry, cooking, concerns, and labor. I came away with gratitude for the opportunity to interact with such caring people, and with a renewed sense of confidence that we will manage to help forge a sustainable future.This year’s Colloquium was organized by the Natural Building Network (www.naturalbuildingnetwork.org) and was hosted by Gunner Tautrim, who represents the sixth generation of this family living on this land since 1866. The accommodations were primitive, with only a small kitchen as enclosed space; the rest of the facilities were rustic pit privies, temporary solar shower stalls, temporary bamboo and tarp meeting spaces, and a nice lawn area. We brought tents for sleeping. All of this was happening with the grandeur of the Pacific coast as a backdrop, and the elemental simplicity and beauty combined to create an appropriate mood for contemplating the benefits of building naturally.
After breakfast each morning we would gather in a big circle on the lawn to review the various options for the rest of the day and share other thoughts. Typically the mornings were devoted to work on a sturdy, permanent, multi-stalled toilet facility that was already framed with wood. Gunner wanted the walls and a surrounding fence to be finished with natural materials, and there were many volunteers who formed teams to accomplish this. Mostly, split bamboo or recycled fencing was used for a framework, over which cob and clay finishes were applied.
Lunchtime often featured tables where specific discussions would occur, having spontaneously been announced at the morning circle. The afternoons were reserved for many concurrent presentations or discussions, so there were always hard choices to make about what to attend. During the course of the week, over forty different topics were explored, in a variety of meeting places. These ranged from the use of materials (such as bamboo, cob, adobe, and lime) to more theoretical discussions about engineering, thermal properties, efficiency, and design. One of the most popular forums was about codes and ways of improving the acceptance of natural building techniques by building officials. I will be writing about this topic in more detail in a future blog post.I shared one two-hour presentation about earthbag building around the world with a woman architect from Israel, who had brought plans for an earthbag residence that she was designing for a client there. First I talked about the history and development of this technique, and then profiled a number of projects that have been completed (see www.earthbagbuilding.com). After this introduction, the architect laid her plans on a table and we all discussed specific questions that she had about them. This was a great way to learn some of the basics of earthbag building, and then apply these concepts to a specific situation.
I was very pleased that a discussion was convened to explore the role that natural building can play in what was described as the “long emergency,” or the compounded effects of climate change, peak oil and other resource depletion, population pressures, and financial crises. Without this discussion I would have felt that we were negligent in addressing these most pressing issues. I plan to write another entire blog post about this. After dinner (which was always delicious and usually vegetarian), we were treated to a variety of programs or entertainment that emanated from our group. Mostly these were slide or Power Point presentations, but one night was devoted to a talent show with lots of music and some stand-up comedy…great fun. I showed lots of pictures I took when in Jeddah, Saudi Arabia a couple of years ago where I had been invited to discuss sustainable architecture with the faculty and students at the King’s University (see www.greenhomebuilding.com/weblog for my essay about the situation there) . 
One morning, about half of us opted to attend a tour of historic adobe buildings in the heart of Santa Barbara. The earliest remnants date to the 1780’s when Spain authorized the construction of a presidio and the Santa Barbara Mission. Much of this early adobe construction was toppled during subsequent earthquakes, but recent reconstruction, using stabilized adobes, has returned the area to its original presence. I chatted (in Spanish) with the Guatemalan and Mexican crew who were making new adobe blocks for further repair work. On the return trip to the Orella Ranch, several of us made a detour to the nearby beach to dip our feet in the ocean. One of the delights of this event was the participation of James from Zimbabwe, Africa. This very engaging fellow brought with him pictures of a lovely little thatched cob circular building that he and some friends had made. He also brought his large thumb piano to serenade us with African ballads. This was a reminder of the deep roots that natural building has from all corners of the world.
All together this week of camping out in this spectacular place and connecting with these dedicated and compassionate souls has left me feeling heartened that we will find ways to overcome the enormous obstacles that lay ahead.On a very foggy night before we were to disperse the next morning, during our closing ceremony, we arranged ourselves in two large circles that faced each other. We (on the outer circle) were asked to assume the role of addressing our ancestors (on the inner circle) from some indefinite time in the future. When I did this I felt strangely like I was really speaking from the future. I told the young woman who was sitting across from me that I did not blame her for the difficulties that she and subsequent generations had endured. I said that the pattern was innocently established well before she was born. Industrialization was fashioned to improve life, not deteriorate it, and the consequences were not foreseen. And then I told her how much I appreciated the hard work she was doing to address and correct the mistakes of our ancestors. I said that because of the actions of her generation, we in the future were enjoying a simple and healthy life based on ecological balance, and that we owe her and many of her generation our gratitude for all that they did to make this possible. We then stood and embraced, the Future and the Present, for a moment of true compassion.

The Florida Homebuyer Home Design Challenge
00/00/0000, 00:00 | LamiDesign Modern House Plan BlogHere is a link to a recently held design competition for Florida home designers. Its very developer oriented, and the house designs reflect that, but what is remarkable is that many of the designs shown as the "best of the rest" are overtly modern.
The Florida Homebuyer Home Design Challenge
On one level I'm very gratified to see modern shouldering its way into this mainstream platform. At the same time I'm discouraged because the homes, while modern, seem to have the same issues as typical developer homes. They are dressed modern, and some I think look nice, but they are bloated and pseudo luxurious in a way that makes my skin crawl. Its not just look and feel, its statistical as well - there is an alarming bedroom count to square footage ratio in most of these homes. 3 bedrooms in 3,500 sqft?
The discussion of "modern" on LiveModern all the way back to the Dwell messageboards always involved doing more with less, as a lifestyle, as a design dictum, not even driven by sustainability, but as a personal value and as an aesthetic. This stuff is really stepping on that for me.

'patchwork pavilion' and 'cave house' by DOMO arquitetos associados
00/00/0000, 00:00 | designboom weblog, design related news, reviews and previews
at night, light shines through the exterior patterned blocks of the 'patchwork pavilion'
'patchwork pavilion' is a temporary art gallery designed by DOMO arquitetos associados. the structure was
originally built for the casa cor 2008, an exhibition for home textiles in brazil. the name of the pavilion is fitting,
as the exterior is constructed from a random combination of four different pre-cast concrete blocks whose
patterns have been inspired by embroidery pieces that originate in the northeast part of the country.
these concrete blocks were largely used in early modernist buildings in brazil, because of their ability to ventilate
and allow light to pass through the patterns, as well as for their low-cost and shape.
the four different patterned tiles create a graphic patchwork effect
'cave house'
DOMO arquitetos associados' 'cave house', was originally designed for a competition called 'luxury for all'
which explores the idea of luxury living which considers our sensorial experience with buildings and objects,
with an approach to sustainability. the structure aims to continue the flow of nature through the cave-like space.
