The green surroundings, and the development of a new typology of affordable houses, following traditional construction regulations, are the starting points for the concept of a greenhouse dwelling. A ready-made steel construction, to be divided up freely, and encased in sheet walls of greenhouse profiles, is the archetype of this box-house. The body forms a qualitative, continuous space over the different building layers. The walls are a combination of transparent, super-insulating glass parts and translucent polycarbonate plates, behind which is put insulation, depending on orientation and required privacy. The reflections of the glass skin, together with the green-yellow sheen of the insulation through the polycarbonate sheets, lodges the house perfectly in the environment, in a subordinate position to the age-old trees. A detailed specification, an extreme standardisation, a very high insulation level, the integration of ecologically sound techniques and a minimum use of materials.
