Integral conversion of a large housing estate

Bonn-Dransdorf-West „Mörikestrasse“

(North-Rhine Westphalia)

Context

The large housing estate Dransdorf-West (1500 residents) was constructed at the end of the 60s until the beginning of the 70s in a district to the north-west of Bonn's inner city predominantly featuring terraced housing. A good public transport connection (< 10 minutes to Bonn main station) and the adjoining free space are positive location factors. The existing estate consisted of apartment blocks with up to eight storeys. They jut out from the surrounding terraced houses and form an alien element. Social cohesion within the large housing estate furthermore increasingly showed itself to be threatened.

 

Project description

The large housing estate was comprehensively redeveloped and converted. Following the deconstruction of a high rise building, 102 residential units (78 subsidized housing units and 24 privately financed owner-occupier apartments in a 3-storey architecture style) were created as part of this development project. At the same time, replacement housing spaces created in further redeveloped blocks could be used for the required interim relocations. One deficit was that the estate wasn’t particularly inviting, especially the ground floor’s open storeys for motorcar parking. These open floors of the 8-storey apartment blocks were converted into business and community facilities. A district square was created between the existing, adjoining housing area and the new buildings via a job creation scheme.

In this project, an integrative redevelopment approach featuring economical, ecological and also social improvements has been realized in an exemplary fashion. Notable features include the extensive resident support, the creation of favourably priced housing, the occupancy management, the gentle high rise conversion, the evaluation of the housing environment and the change of use of formerly open storeys.
