The beauty of an open source house is in its simplicity. Designed as a kit of parts that can be downloaded, milled, then assembled, open source homes are, by their very nature, boiled down to their most elemental pieces.
This tiny cubes of a house from Dutch studio RoosRos Architecten is an update to the WikiHouse model of open source architecture. RoosRos designed the Petit Place as a kit of wooden elements that can assemble into a massive variety of sizes ranging from 270 square feet to 10,000 square feet depending on the number of parts in the plan.
The buildings are constructed by assembling pentagon-shaped slices of building that when connected form a long, shotgun-style house. The facade of is built from a grid of wooden squares that have been insulated in a gore-tex foil that wicks water and protects from wind. The exterior also features a grid of solar panels, which generates 9,000 kWh per year, roughly three times the amount of energy needed to power the home.
The Petit Place is designed to be built just about anywhere. All you have to do is download the plans, find a place to fabricate it, and then voila—you’ve got yourself a simple, beautiful, and most importantly, totally efficient home.
