125m2 wood/slipstraw house - 40m2 earthbag bathroom - 85m2 earthbag/wood/slipstraw/green roof housing

2018 – …

Slipstraw House

Started in 2018, this construction project is our most challenging so far: a three rooms 125 m2 wooden house with slipstraw wall infill and perlite/cellulose floor/roof insulation. The structure sits on 110 steel rods screwed two meters into the ground. 30cm thick panels made of wood and OSB insulate both the floors and the ceilings. Large openings to the south insure maximum solar gain in winter. The U shape of the building provides a patio sheltered from the dominant winds. This house will be fully solar powered.

Bathroom Building

Designed for campers, this 2 showers/2 dry toilets unit is based on curved earthbag exterior walls coupled with two straight slipstraw interior walls dividing the spaces. Cob bottle walls on both sides bring a special touch to the toilets. Showers are finished with tadelakt lime plaster and the exterior walls are protected with our special water-resistant “mayonnaise” earthen plaster.
