Atelier Kempe Thill’s project is located in the central high-rise cluster of Bajeskwartier and is part of an ensemble of four residential towers up to 60 meters high, grouped around a small neighborhood square. To create a meaningful degree of architectural diversity, each of these four buildings has been designed by a different architect. Residential building “De Vrijheid” has been commissioned by housing corporation De Alliantie and contains 140 social housing units, divided into 2-, 3- and 4-room apartments. Additionally the building houses commercial spaces and resident bicycle parking in the plinth.
The design capitalizes on the specific qualities of the urban context. The robustly designed plinth, consisting of large prefabricated terrazzo elements, has a public character with vistas into the building. On top of the plinth are the residential floors, with the accent on the magnificent views from the apartments. All around balconies behind a clear grid, with large subdivisions, create a calm image. A communal and spacious atrium houses planters and a 10-meter high tree. In the atrium, all around galleries and staircases provide interaction between residents.
The project stands as a social housing block in the midst of expensive private residential buildings, altogether meeting the same urban planning, sustainability, and aesthetic requirements of the master plan. To realize the project within the strict social housing budget, the project has been conceived with specific cost-saving measures such as a very efficient, compact layout and prefabricated construction. Additional to this economical efficiency, energy neutral homes are offered, with triple-glazed façades, all around balconies for passive shading and a heating and cooling system that ensures comfort year-round. There are green roofs and photovoltaic panels and the structure’s lifespan is over 100 years, with flexibility for future modifications.
The materialization was designed to be both high quality and robust. Oak and terrazzo were used in addition to exposed concrete walls and a polished concrete floor. The apartments have facades with floor to ceiling glazing to extend the flats outward and make them appear more spacious. All apartments have façade long balconies, accessed through a 2.3-m by 2.3-m sliding window. The corners of the building have been openly designed to create a sense of lightness both inside and outside. Overall, an attempt was made to consciously apply C.I.A.M. principles, such as light, air and panoramic vistas, in the interior as well. The aim has been to show that a certain degree of spatial luxury is also possible in social housing.
