+2edison7 is a stunning renovated LEED platinum residence by Studio 27 Architecture, located at the corner of 27th and Edison Street in Arlington, Virginia. Before the renovation, the home was a modest, two-story colonial, built in the post-war moment when houses were small and cars were large. Today, this mid-century residence is a graceful composition of brick, glass and wood-accented rain screen known as +2edison7—Studio Twenty Seven Architecture’s playfully disjunctive name for this high-performing renovation with humble bones.
As the personal home of one of the principals at Studio Twenty Seven Architecture, this home was a design and research project that sought to revitalize a typical suburban residential building with modern amenities and sustainable retrofits while adjusting the building’s spacial program to account for site conditions and orientation. The renovation more than doubled the volume of the original building, from 1,300 square feet to 2,800 square feet; yet its systems operate at more than 60 percent greater efficiency than before.
The stairway draws inspiration from the way that light dapples down through two maple trees which were on the site. A photo of the maple leaves was adapted to a pixelated contrast pattern and then translated to a template for milling machine, which then milled the wood.
Despite substantially up-sizing the house, the architect’s research led the firm to maintain the neighborhood scale as a reference point. Working off of the existing masonry core, the architects realigned and expanded the home away from the public street and towards the quiet of its garden. The density and rhythm of the neighborhood suggested a design based around scale modulation and precise viewpoints. The house massing builds from the scale of the original core, and a new addition up top opens the house to the site situation. Each window was carefully located to mediate the public-private threshold of the site, focusing on the most compelling views yet allowing privacy and capitalizing on daylighting. The result is a house that is open, capacious and airy from the inside, but discreet and slightly introverted from the exterior.
Sustainable strategies further reduced resource consumption, including energy-efficient LED and CFL lighting, and ENERGY STAR appliances and ceiling fans. To minimize water use, dual-flush and low-flow toilets are used, and showers and faucets are equipped with low-flow aeration devices. Water usage for this single-family home has been cut in half. Additionally, the house’s original wood floors were salvaged, and supplemental flooring was provided by sustainably and regionally harvested forest providers associated with FSC. Countertops are recycled porcelain, glass and mirrors suspended within an epoxy resin. The exterior is a palette of durable, low-maintenance and high recycled content products such as integral color cement board and epoxy resin color panels. Reduced care requirements on products ultimately reduce continued chemical and manufacturing requirements, while also allowing the homeowners to spend more time in their garden.
The home has garnered multiple certifications, including USGBC’s LEED BD+C: Homes v3 Platinum and Home Innovation Research Labs (HIRL, formerly the NAHB Research Center) National Green Building Standard (NGBS) Gold Level. It is also certified as an EPA ENERGY STAR New Home, EPA Indoor airPLUS home, and locally at the Gold level in the Arlington County Green Home Choice award. Finally, the yard is a National Wildlife Federation Certified Wildlife Habitat. Indeed, +2edison7 may hold more sustainability accolades than any post-war tract home in the mid-Atlantic.

Project Portable Home ÁPH80 is a design by Madrid based ÁBATON Architects, a dwelling ideal for two people, easily transported by road and ready to be placed almost anywhere. This tiny house is comprised of only 290 square feet (27 square meters), sectioned into private and public spaces and ready for immediate placement. The proportions are the result of a thorough study by the architectural team so that the different spaces are recognizable and the feeling indoors is one of fullness. This low cost pre-fabricated housing solution is priced from $42,862, with an estimated one day assembly time and manufacturing taking approximately 4-6 weeks per unit.
If you’re into mobile architecture, check out a sled house retreat that can be towed off the beach to avoid incoming tides.
It is a simple yet sturdy construction made of materials chosen to provide both comfort and balance. ÁPH80 embodies the principles and objectives of ÁBATON: wellbeing, environmental balance, and simplicity.
ÁPH80 has 3 different spaces measuring 27 square meters (9×3): a living-room/kitchen, a full bathroom and double bedroom. Its gabled roof is 3.5 meters high indoors. Most of the materials can be recycled and meet the sustainable criteria that ÁBATON applies to all its projects.
It blends in with the environment thanks to its large openings that bring the outdoors inside. The use of wood throughout the building not only adds calmness and balance but it is also hypoallergenic. The sourced wood comes from regulated forests (will regrow to provide a wide range of other benefits such as further carbon storage, oxygen generation and forest habitat).
Technical Data: The outside is covered with grey cement wood board. Ventilated facade with 10 centimeters thermal insulation around the building. Solid timber structure manufactured through numerical control; Inside timber panels made of Spanish Fir Tree dyed white. ÁPH80 has been designed and manufactured fully in Spain.
Manufacturing time: 4-6 weeks. Assembly time: 1 day. Transportation by road. We are currently developing simpler series which can be added to the ÁPH80 to suit every particular need, creating larger spaces and contributing to the project’s versatility.

We just received images of this net zero home that was designed by HMH Architecture + Interiors in Boulder, Colorado, for two environmental attorneys. One of the attorneys works for the Environmental Protection Agency so maximum sustainability was the only option. However, the environment wasn’t the only design caveat. The owners—a small family with two dogs—also needed a showcase for their expansive art collection of two- and three-dimensional pieces, and requested casual living spaces to accommodate everyday living.
The house was designed in three zones: public, private and the garage. An entry that functions as an airlock separates the garage from the public zone defining the entry as well as help keeping pollutants from entering the main house.
After interviewing several firms in the area, the owners chose HMH Architecture + Interiors in Boulder, Colorado, a firm that specializes in art collection-driven home design, to create home that would be a work of art in its own right.
A seamless integration of the environment, art and family life, the home is a sculptural plan with long, uninterrupted walls throughout to accommodate and complement the art collection. Windows were carefully sized and located throughout to optimize daylight and art lighting while sheltering the works from direct sunlight.
A living room designed for living. This great room area includes the kitchen, dining area, an open office for homework and telecommuting, a living area for family interaction, and a covered porch for eating and playing outdoors.
To achieve an architectural balance between high-concept design and environmental efficiency, the home was built with sustainable materials throughout, including more cost-effective stucco and metal for the exterior.
“The main goal was to build a house that didn’t leave a carbon footprint,” says principal Harvey Hine, who conducted energy modeling prior to construction, which dictated that the house had to be built with fewer windows than originally intended.
The window design was a study of transparency and heat control optimizing the ideal amount of sunlight to keep the home cool in the summer and warm in the winter. With a 10kW solar intake system on the roof and a hot water solar system, the home produces 140% of its energy every year, and the homeowners sell the excess back to Xcel Energy.
No matter how sustainable or sculptural, a home ultimately has to be comfortable and livable, which was the top priority for this small family who wanted the home to serve as a social center for guests and entertaining. The great room includes a kitchen, dining area and an open office for family interaction as well as a covered porch for eating and enjoying the legendary Colorado weather.

Hupomone Ranch is a certified LEED Platinum project designed by Turnbull Griffin Haesloop Architects, nestled on 150 acres in the Chileno Valley, just west of downtown Petaluma, a city in Sonoma County, California. The ranch is an original homestead that had been neglected for over 30 years and the owners wanted to build a family house that would reflect their commitment to sustainable farming, draw on the natural serenity of the site and build on the sense of place in western Petaluma where farming and ranching are still a part of people’s daily lives.
The site has a wonderful balanced quality to it, and the simple grounded form of the barn is sited to compliment this setting and capture the long views to the coastal range beyond. Entering a low porch on the more opaque north side under the loft above, the light-filled house opens up to the expansive view of Sonoma hills to the south and gathers the bedrooms and kitchen to either side.
The house is certified LEED Platinum and features a number of energy saving features exceeding title 24 by over 50 percent. Passive heating and cooling with thermal mass and insulation, Geothermal, radiant cooling and heating along with solar and photovoltaic panels contribute to the house’s energy efficiency. All materials for the project also had to meet specific guidelines, such as lumber that had been sustainably harvested , products produced within a certain distance from the project, or a specified percentage of recycled content.
An integral part of the design, the landscaping by Lutsko Associates includes several outdoor living areas, organized along a riparian restoration and native plantings. To tie it all together, Erin Martin’s interiors compliment the flow of indoor/outdoor living.

Modern Green Renovation has been carried out by the design team of Marken Projects who turned a 50’s bungalow in Vancouver, British Columbia into a durable, modern and energy efficient home. They added a half storey maximizing the allowable living area (FSR) with the focus on improving the overall energy efficiency, using environmental friendly materials and ensuring a healthy indoor environment for this young family to enjoy. At the same time they gave it a new and exciting look. From the architects, “For us, it is common sense to plan along the Passive Design principles, which essentially means optimizing solar gain, optimizing insulation, ensuring an airtight envelope, installing a high performance heat recovery insulation system and making the house as energy efficient as possible.”
Main energy-efficient features in the home includes: Modern Passive Design, Low-VOC Products, Energuide 86, Air-to-Air Source Heat, Pump for Heating, Airtight Envelope at 1 ACH, Efficient Heat Recovery Ventilation.
The different blue colors on the exterior facade of the residence is stucco. The porch ceiling is engineered cedar wood.

Net Zero Energy House is modern two-level home completed in 2011 by Klopf Architecture, situated in Cupertino, California. The goal of this project was to score as high as reasonably possible in the “GreenPoint Rated System”. The owners de-constructed their existing home when they realized that any single-story design would completely eliminate their back yard. They wanted the design to be a contemporary interpretation of Eichler in style yet keep their single story neighborhood happy. They wanted to maintain their privacy but also wanted a design that was open and light-filled.
The solution: directed openness, low profile and net-zero energy. The site is a cul-de-sac lot which was the not large enough for a single-story home that would fit the needs of these owners who both work from home. They wanted this to be their “final” residence so Klopf needed to design a larger-than-normal home to suit their lifestyle needs. Instead of adding a second story (and annoying the neighbors) they opted for a partially-submerged lower level that Klopf designed furthest from a basement as possible (with a pulled-back floor plate, a light-filled “atrium” and a lower level light well).
To preserve privacy and bring in light while minimizing unwanted solar heat gain and provide connection to nature, the design team oriented a large window wall north to the back yard while sloping the ceiling of the great room up to increase the light and connection to nature. The sloping roof also provided a surface suitable for mounting the 13.4 kW PV system compared to other building faces that have smaller, punched windows that maximize privacy. The owners were very concerned about the environment, specifically about energy and resource efficiency. They directed Klopf to use materials that would last as long as possible while avoiding “food for termites” and design a high-performance sustainable home.
In conjunction with the Mechanical Engineer they designed a net-zero energy home featuring insulated concrete forms (ICFs), structural insulated panels (SIPs), high-performance windows, cementitious siding, and a 13.4 kW solar Photovoltaic (PV) system sized to cover all the energy use in the house. The new open and light-filled house offers a connection to nature while maintaining privacy. Natural gas would not be used in the home with the possible exception of a backyard BBQ.

Hacienda Ja Ja is a LEED-Platinum home nestled beneath a canopy of live oak trees, designed by Lake Flato Architects, in Alamo Heights, Texas. The 2,328 square foot property is to scale with its neighbors, offering porches that allow its residents to easily engage with activity on the street. Spaces wrap around a small courtyard to maximize natural lighting and ventilation distributed throughout via tall glazings and high ceilings. High-performance features include details like the variety of floors made of polished fly-ash-content concrete, locally sourced stone, engineered wood and locally sourced wood siding installed as a rainscreen system.
Carefully sited to preserve and to protect the live oaks, to promote cross-ventilation and to maximize natural daylighting, the home is also designed to avoid solar thermal gain during the summer and capture passive solar heating during the winter.
Rainwater is collected from the roofs and stored in a below-ground 6,000-gallon tank; during most of the year, captured rain water will supplant domestic water for all landscape irrigation needs.

MINIMOD is a modular home designed and built for relaxed, off-the-grid living, designed by MAPA Architects, situated in Maquiné – Rio Grande do Sul, Brazil. This 290 square foot (27 square meters) module proposes an innovative, intelligent and sustainable alternative of dwelling. Starting from a minimal module, MINIMOD invests in customization, design and sustainability. The production is carried out in a prefabricated manner and enjoys the steel frame system technology, which lets the client adapt the space to his needs, choosing among different finishes, as well as automation options.
Depending on the composition of the modules, MINIMOD can vary the uses ranging from a compact refuge for weekends, a small showroom for events, up to hotels and inns, combining a larger number of modules. The modules are 100% prefabricated and elevated to a determined place by truck or disassembled into smaller pieces and taken to the ground for final assembly.
The expansion and addition of new modules can be performed either at initial installation or in the middle of the process, according to the needs and budgets of the client.
MINIMOD is more than a product of design, is more than a house. It’s practicality combined with comfort, it’s economy allied to nature, it’s a unique experience of housing and contemporary living.
MINIMOD centralizes production and reduces the emission of CO2 in the atmosphere. The home features a rainwater harvesting mechanism through the green roof. The house is slightly elevated to avoid moisture from penetrating the interior. Ventilated facade gives thermal and acoustic comfort. When night falls, this modular home uses LED lamps to illuminate its interior.
The MINIMOD enjoys the benefits of dry construction technology: quick, clean and efficient. Entirely manufactured and pre-modulated it is easily adaptable to customer needs. Mounted and manufactured in accordance with the premises of the project, it can be transported entirely or in parts.
