The buildings are designed with clearly defined functional and thermal zoning. In stead of wrapping insulation around the entire object, only the zone with apartments is insulated, while the corridors, staircase and the garage remain unconditioned. By dividing the building into zones, the heated area is reduced by 18%.

The facade, as well as the construction system, are designed with prefabricated, modular elements, dimensioned so they can easily be transported with regular size trucks. This guarantees fast, effective and cheaper construction.
