With its fields and meadows located in and around Almere, De Kemphaan biodynmaic farm contributes to the city's green space. The architecture of the barn and farmhouse are, like the agriculture, based on athroposophy. Its sustainable building materials and sloping lines can be traced to Ballieux' long period with Albert & Van Huut. With rooftop solar panels and a geothermal reservoir, the building provides its own heating and cooling. Besides storage, the barn shelters a Saturday farmers' market and cultural activities.
