14 adjacent parcels in the Lootsbuurt in Amsterdam have been replaced by 34 modern dwellings on an underground parking. The tension between the differentiated historical fabric and the standardized characteristics of contemporary building techniques is translated into a hybrid block. On the garden side the block follows the meandering contour of the original buildings. Together with the constructional stramines determined by the underground parking this meandering contour creates a variety of conditions for dwelling types, outdoor spaces and access typologies. In this way the contradictionary aims of sun-orientation, privacy and access at the south façade can be solved at the same time. On the streetside the block fits gently in the existing urban fabric and reflects the hybrid block structure by showing in a subtle way the diversity of dwellings. A rhythm of windows with identical width is dancing up and down influenced by the different dwelling types. In this way a homogeneous and differentiated layout of the facade is created. The garden facade has an informal character. The presence of galleries, balconies and terraces creates a strong plasticity of the volume. The facade is treated as a transparent filter that provides daylight into the dwellings and provides privacy when needed.
