Interior Decorating
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.

Cliffhanger - Alvaro Ramírez and Clarisa Elton - are the authors of their own weekend retreat on the central Chile coastline. Great residential design, propped on stilts, with minimal environmental impact.
{Reworked article from Plataforma Arqutectura Author:David Basulto [tricky]}
This great house is located on a remote coastal trail in central-south Chile, in Buchupureo, VIII región del Bío-Bío. When I lived in Concepción, the capital of the region, we'd surf here. The waves were fantastic, rolling into all the bays around this area. Getting there was difficult and the water was freezing (pushed up from the Antarctic), but the untouched waves, scenery and beaches were, and are still, amazing!
The project was developed in dialogue with its environment, both through the materials used for creating the volumes, as well as how these are implemented and placed on the site.
The house is supported on a steep slope through piles, which lessen the intervention/excavation of the plot's soil, allowing in turn, the free passage of water.
The cabin is divided into three functional spaces, relating to the three requirements of a holiday house. A bedroom with bathroom; a space for entertaining and guests - being with the kitchen; and a terrace, linking the other two spaces and providing spot for those spectacular views. All spaces seeking panoramic view towards the Pacific Ocean. The terrace serves as the lobby space, an intermediate space, as it is located between two interior spaces, providing protection against the wind and and as a place to embrace the ocean.
The structural elements of the house are left visible, giving form to the shape of the house. The structure, external and internal elements, are all created from local wood (the equivalent of Radiata pine), yet treated differently depending on their role. For the pillar structures and beams pieces of 4 "x6" 2 "x6" and 2 "x5" were used. All were treated to give them protection against moisture.
For interior cladding, ¾" x 4" pine are used,brushed, without any treatment. Finally for the external cladding 1" x 4", painted with carbolineum.
The tectonics of the project establish a close relationship with the local architecture, using wood and 'laja' stone, materials predominant in the area (most of the fences in the area are built with laja stone and mud, as well as many old house floors).
The structure of the roof is wood and in its V design, it detaches itself from the wall structures at both the front and rear of the house. This letting light into the interior,generating a feeling of spaciousness. Laja, the stone used to cover and protect the roof, was thought of as an element of both cultural adaptation (local architecture) and natural (landscape elements), blending the building into the rocky shores below. Conversely the view up from the beach sees the timber framework match the colours of the cliff face, the house's home.

Interior Decorating
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.
