Holtenau Ost Kiel

3rd prize in urban and open space planning design competition with 15 teams of architects, urban planners and landscape architects. The redevelopment area in the Holtenau Ost district of Kiel covers a total of 92 hectares and, with its 26 hectares of forest and 14 hectares of water, borders directly on the Flensburg Fjord. It is strongly characterized by the juxtaposition and coexistence of land and water, density and space, different heights and depths, undeveloped and built-up areas, building areas from different eras, with dimensions and values, as well as different infrastructures. The plot is divided into three areas: The first is the commercial area to the north, the second is the “island” with differentiated planned residential typologies and the third lies in the south and shows purposefully placed tower buildings, which on the one hand harmonise with the detached house structures, while on the other hand differing from them in variance, scale and height. A uniform architectural language brings the varying characters and functions of the areas together to form an overall unified area, that through the landscape becomes a spacious, natural park, which is experienced through and connected by public spaces. The design, developed jointly with Atelier Loidl and the Dutch urban planning office Posad Maxwan, follows a climate-neutral approach: striking a positive balance between biodiversity, new buildings made of wood (recycled wood and new planting of climate-adapted trees), recycling and conversion of existing resources and the planting of many existing roofs with green plants . A mobility hub is planned in the central core where cars can be parked, modes of transport changed, parcels delivered, and generated energy stored and redistributed.
