Residential greenhouses by Lacaton&Vassal 
This is a house whose roof is resolved with polycarbonate domes. The air space under the dome is renovated with a roof ventilator.
The dome extends beyond the nuclear housing to cover an intermediate space, working as a greenhouse. The climate of Mulhouse fully justifies this choice. This is a space that can be almost exterior by opening the sliding outer perimeter but ensures a proper temperature on a sunny winter day. The furnishing of this space explains its use in family life.
To control the excess of radiation in the space, L&V architects arranged horizontal awnings and vertical curtains all around the perimeter. Their interest of these elements lies in its thermal insulating and radiation reflective character. They are made with polyester.
