Each living area is a separate house. This concept was mainly established for the concept of privacy. The houses are built on slate hills and due to their elevated position, offer breath-robbing sights to the north and south. Due to several window fronts the houses can be opened up to optimise air circulation during the heat season and at the same time make it bright and friendly. The planting of trees was consciously avoided, in order to stress the naturalness of the rock-garden.
