The sloping green roof is planted with several species of flowering plants that change appearance throughout the year. The home’s facade is sheathed in a rubber membrane that waterproofs the interior and gives an opaque look to the exterior. A large protruding volume marks the main entrance and acts as a passage that leads below the surface of the ground. The only other visible volume is a large window that allows natural lightto flood the dining area.

In order to bring more light into the interior and create a feeling of spaciousness, the architects decided to treat different rooms as split levels. They situated the bedrooms on the lower floor, while split-level floors above contain living areas. The soil keeps the bedrooms cool in the summer.

“Unlike most single family houses in Belgiumhttp://inhabitat.com/tag/belgium/, [we] started with the idea of positioning the living rooms on top of the bedrooms,” said the architects in a project description. “In a house composed of split-levels it was important to establish cross relations between the spaces and natural lighting conditions throughout.”
Natural materials were used throughout the interior, with a stone-clad fireplacethat doubles as a barbecue accessible from a terrace connected to the living room and kitchen.
