The realized building consists of the simple stacking of two - diametrically opposed - concepts of space. The ground floor level is designed as a flat sandwich-space, which opens up completely to the glazing on all sides. The public green with its dominated tree canopy becomes part of the interior and generously extends the small space to the outside. This effect is enhanced by the modest interior design and the greyish colour scheme. Used as a "public living room" of the neighbourhood, activities on the inside are well visible and stimulate the direct interaction with the public space.
