MAISON EVOLUTIV' 1
CERTIFICATION : THPE 2005, H&E PROFIL A
At just 70 square meters (about 753 square feet), this energy efficient abode is made of two prefabricated modules perched one on top of the other. Rather than box out the structure with a stacked configuration, we pivoted the top unit to create a variety of interesting and integrated outdoor spaces, as well as a variety of structural possibilities.
The beauty of this design lies in its chestnut façade and inviting floor plan, but also in its small ecological footprint. The Maison evolutiV consumes only 48 kWh/square meter per year. Solar thermal on the roof provides hot water and wool wood insulation helps keep the structure’s temperature regulated. Rainwater harvesting provides water for toilets and landscaping.
With green roof possibilities and a playful layout that invites interaction between indoors and out, we think this tiny prefab combines a multitude of great design ideas.
