• The house layout is based on solar orientation, resulting in passive solar gains throughout the year.
• Photovoltaic power generates household electricity through a 2.8kw system (when power is not needed, it feeds back into the grid).
• A passive roof-top solar heating system provides for domestic hot water and a passive solar ground-level hot-water system is used to heat the pool.
• The natural flow of hot and cool air is fortified by the use of radiant hot-water floor heating and separate central air conditioning in the ceilings. - Although these systems are in place, they are rarely used because of the solar orientation of the home and the natural ventilation.
• The architects re-used the existing foundation and caissons. During construction, the existing house was taken apart piece-by-piece, with all usable elements donated to Habitat for Humanity.
• Other energy-saving systems include double-pane windows, UV-resistant glass, ample insulation, and energy-efficient appliances.
• Deep exterior overhangs are designed to provide shade in the summer, and let in sun during the winter.

• 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

Program
The initial task was to renovate the original 1976 dwelling into a contemporary urban retreat, whilst adding some structural reinforcement. Bought in 2001 for it's location, the owners, together with the architects, went on to extensively remodel the house into an urban oasis. Concious efforts to negate the road behind and emphasise the beach in front are evident throughout.

Design
The overall concept for this 2,900-square-foot beach-side modern house was to transform it into an urban spa-like retreat. The house is perched along Malibu’s Pacific Coast Highway, and features access to the beach at the back. Sheltering the house and providing a hard façade is the garage to the rear. As an area of transition between the street and beach, an interior entry courtyard behind the garage, laid with rectangular cement pavers and bordered by smooth river rock and tufted grasses, introduces the primary design element of the home — a seamless union between interior and exterior spaces. Through crisp linear architecture, a split level plan, and visual access throughout the house brings in the beach.

From the entry courtyard, a line of sight straight through the living room takes in the sea views. Dragging your attention away, to the left is a bay window type dining room, accented by a white grid of window panes and shadowed from the noon sun. This window grid is echoed by the geometric pattern of the cabinets and shelves that lead into the minimal kitchen. True to the open plan, the kitchen seamlessly overlooks the main living space, allowing distractions whilst cooking.



The interior design palette of natural woods and limestone, white walls and fabrics, frosted and clear plate-glass creates a crisp and airy environment to appreciate the Pacific Ocean setting. A true Urban Spa,the elements were hand picked to portray the theme of air, light, and water.

Ground-floor living room and adjacent sitting room offer shadowed relief from the sunlit terraces beyond, with cooling white and dark wood tones in the furniture and materials. Double-paned windows, which open onto the first-level terrace, offer several ways for freedom, permitting unrestricted views onto the ocean while buffering sound (from the highway).



The upstairs rooms continue the overall theme of air, light, and water with repeating materials and colours. The well-dressed master suite faces onto a second large terrace with pocket-glass doors that fold away, converting the stepped upper terrace into a sleeping porch reminiscent of designs by Schindler and Neutra (and last weeks post - David Hertz! [Image]).
For reclining on the teak chaises, billowing fabrics can be drawn above and alongside the terrace to shield the sun and wind.

With the clients goal being a boutique like retreat to entertain guests rather than as a reclusive beach getaway, opulent bright-white materials: Limestone and high gloss surfaces were used to give that crisp light filled feel. In fact, the owners found it too 'bling'. The house was cool crisp and far too full of light, with the white being overwhelming sometimes. Aware of this, Shubin + Donaldson had already incorporated exterior shutters and shades, which compensate in the southern facing rooms. Then in terms of layout, a simple North facing Media room was added with minimal windows at the rear, providing a further space to retreat in summer, and a little getaway for all.



Openness and transformation are themes throughout and are most expressive in the master bath. Cool, ocean-blue frosted glass lines the walls and windows (that face another house on these sought-after lots). Behind the glass swing doors are the toilet and shower. Three layers of floor-to-ceiling glass form a translucent door that closes the space off from the bedroom, or opens it up to the master suite, porch, and Pacific Ocean beyond. Dark wenge wood - used throughout the house as an accent - encases the tub, vanity, and spacious closets. The rich brown colour gently contrasts with the limestone counters and floors. Double mirrors are placed on poles in front of the frosted glass, rather than set into a wall. To name-drop, the tub is designed by Philippe Starck.

Layout
First level: living room, dining room, den area, terrace with beach access, powder room. Upper level: home office, guest room and bath, powder room, media room, and master suite with bathroom/walk-in closet, closet office, outdoor sleeping porch.

Overview
The project is located on a small, 37 foot wide lot on a pedestrian only street in Venice, CA. Rather than create one solid object, David followed his residential design signature of two, two story units. The upper levels of the units seeming to float above minimal tilt up concrete walls and pillars of the lower levels. The two upper levels being attached by an open-air bridge. The larger of the structures is used as a residence while the other is used as an art studio and guest room over a garage.

The glazed panels, central to the floating effect are also large, sliding doors that conceal themselves so that the ground floor appears to be open to the exterior courtyards, thus blurring the definition of interior and exterior spaces. A large 2-story chimney wall frames the rear of the courtyard while blocking the overlooking 2-story neighbours. The exterior fireplace at the second floor flanks an outdoor sleeping porch and seating area off of the perforated breezeway bridge. Ipe, and black steel are used throughout the house to complement the Syndecrete® prefabricated concrete panels.

Walls on the first floor are intentionally held from touching the ceiling of the second floor to allow for a clear line of site over neighbouring residences and giving the illusion that the second story is floating above the first floor. These clerestory windows also bathe the lower level in light. The mass of the second floor elevations is divided into sections of positive and negative spaces that reinforce the destabilisation of the wall plane. Some of the vertical slices are specific to selective views of nearby palm trees.

A central floating stair divides the spaces and leads to a usable roof deck framed by high solid parapet walls providing privacy and strategically edited views of the distant landscape.

A continuous skylight, that opens to serve as a shaft to facilitate stack effect ventilation, frames the stairs that float from the ceiling of the second story. The exterior walls of the second story are covered in a smooth, steel trowel, integrally pigmented, stucco. These are connected seamlessly to the interior ceiling of the first floor, their continuation internally to form one single mass, further emphasises the weight of the "floating" block above.
