With its urban redevelopment strategy in the inner city redevelopment areas, the city of Berlin is pursuing a number of goals in parallel. As a result, climate, energy and socially sustainable neighbourhoods are to be created.
The implementation of the sponge city concept is one of the main tasks at the building level. Away from heated, dead surfaces; towards unsealed, natural spaces.
The property at Badstrasse consists of a typical Berlin mix of retail, residential and commercial space. On the roof of an existing food retailer, new buildings for residential and commercial use are being erected in timber construction. The area of the roof that is not built over will be designed as a communal garden for the residents. The existing front building from the 1960s will be renovated to make it more energy-efficient and topped up.
The following principles will be implemented as part of the redensification:
- Densification of the existing plot by extending the existing buildings and adding new buildings.
- Preservation of the existing building fabric,
- Construction of the new buildings in timber construction,
- Creation of intergenerational, inclusively designed living space,
- Creation of a favourable microclimate through the creation of community green spaces,
- Introduction of active water management with rainwater retention,
- Use of regenerative energy sources with energy recycled into the
energy back into the urban supply network.
- Use of waste heat from the grocery retailer as thermal support for the residential units.
Using BIM-based planning, the existing and new materials are located and made available for later reuse as urban mining.
Together with the flats in the front building, a total of 55 flats and 3 commercial units will be created.
Existing flats: 35
Existing retail: 1
Flats new: 20
Commercial new: 2
In ∑ = 58 units
