You can click over to the article to wander through all ten. I’d like to feature a few I really like.

The ZEB Pilot House
International architecture firm Snøhetta has partnered with Norway’s Research Center on Zero Emission Buildings (ZEB) and to design and build a remarkable experimental house that helps move the development of very efficient buildings forward. The ZEB Pilot House is claimed to generate almost three times the amount of electricity it requires, with the significant surplus available to help run an electric car, for example…
A lot of sustainable technology was used on the build. The roof sports a 150 sq m (1,614 sq ft) photovoltaic array, and a 16 sq m (172 sq ft) solar thermal panel array, in addition to a rainwater collection system that provides water for toilet and garden use. In order to ensure all available rays are caught, the roof also slopes 19 degrees toward the southeast.
A Snøhetta representative told Gizmag that the photovoltaic array is expected to produce 19,200 kWh annually, while the home’s total electricity needs are calculated at just 7,272 kWh per year.

Pop-Up House
Whatever kind of home you live in, the chances are it took longer to build than the Pop-Up House, by French architecture firm Multipod, which was erected by a team of builders in just four days with no more tools than a screwdriver. The firm likens the construction process to building with Lego.
The Pop-Up House is a prototype prefabricated home that Multipod aims to bring to market for around €30,000 (roughly US$41,000). Thanks to its excellent insulation and near-airtight thermal envelope, no heating is required for the home in its location in Southern France, and it meets the very exacting Passivhaus energy standard.

The S House
Vietnam’s Vo Trong Nghia Architects has been tinkering away at the issue of providing practical, sustainable, and most importantly, cheap, homes. The result is the S House, a US$4,000 dwelling part-built using local, easily-obtained materials, including Palm leaf thatching and bamboo.
The interior of the S House is very basic and measures just 30 sq m (322 sq ft), with one large interior space. The building is prefabricated and can be disassembled into multiple small pieces for easy transport by local builders. Vo Trong Nghia Architects is still working on the design of the S House but the eventual plan is to mass market it.
I could wander off into the tech of these three. I shan’t. Wander through the series and reflect on your own choices – and why.
The last two, the S House and the Pop-Up are my favorites of these three because of size. I firmly believe smaller is usually better. My wife and I [and a dog, of course] first lived together in a 2-bedroom guesthouse that encompassed 650 sq.ft. – and we didn’t use one of those bedrooms. We lived day-to-day in about 450 sq.ft. and that still was more than we needed.
We live in more space, now, and once again have a room we don’t use at all. The guesthouse is back to being a guesthouse. A functional design when you live within a destination. It’s convenient to have two bathrooms; but, still, the main room could be smaller and that would simply encourage sitting closer to the TV set watching a football match or a movie. 🙂
