I’ve noticed the Maison EvolutiV of late and it’s quite the interesting home. Designed by Olgga Architects as a show house for the Salon Europeen du Bois, this energy-efficient home presents a compelling view of what can be done with only two modules. The ground module is flush with the outdoors and features a skin made of chestnut stakes of various sizes. The second module juts out over the first and provides a nice little spot for a green roof area. In addition, the home features a rainwater recovery system, wool wood insulation coupled with cellulose, solar panels, and a low-energy passive house design.
