General information
In Karlsruhe-Rintheim, a pioneering construction project was implemented by increasing the number of storeys on three existing garages as a redensification of a post-war housing estate. Twelve apartments were created while the garages remained in use. The additional storeys were built in timber construction and are characterized by their relocatable and recyclable design.

Research orientation
Research questions
- How can science initiate and scientifically explore changes in the city in cooperation with partners from the field?
Cooperation
Type of co-creation
Those collaborating in the project pursue the co-creation approach intensively in only one phase of the project. In addition, the co-creation approach is applied in cross-process phases by involving people with practical and professional experience in decision-making about how to proceed.
Society involvement
Information opportunities are offered to organised civil society and/or local society.

Organization and decision-making
Constellation of actors in daily project work
Relatively “normal” day-to-day project work: the architect controls the planning process, closely supported by Volkswohnung project management, which also makes the corresponding decisions. Everything is supported by specialist planners. A weekly planning jour fixe has taken place.
Project management
The architect was commissioned with project phases 1-8, which corresponded to a classic project organization. The timber construction (as a “tight shell”, i.e. with windows, sun protection, sealing, etc.) was granted first.
Result and effect
Results and impacts in terms of affordability and other ecological and social target values
- Circularity: A circular and single-type construction method was used, including the avoidance of bonding and composites. Materials were reused via urban mining.
- No use of materials and low-tech approaches: A robust construction method, for example using timber stud walls without foils, helped to conserve resources
- Life cycle-oriented planning: The buildings can be moved and can continue to be inhabited at another location. They can also be easily dismantled at the end of their life cycle thanks to the use of easily removable materials.
- Use of particularly sustainable building materials: materials such as hemp insulation, titanium zinc facades and wood with little or no glue contribute to recyclability.
- Particular durability of the components used: Materials, constructions and the products are designed to have a long service life and can be repaired.
- Building health and freedom from pollutants: The construction method ensures a healthy environment for the residents.
- Sustainable utilization concept and sufficiency strategy: Living space is created without sealing new areas. The relocatability of the buildings enables flexible use and contributes to the conservation of resources.
- Preservation and reuse of existing buildings: The garages will be preserved as such and integrated into the project.
Experiences
Helpful insights & solutions
Experiences
- Project/construction project:
- Importance of service phase 0. The architect developed the concept without a specific commission, won an ideas competition with it and ultimately found a partner for implementation in Volkswohnung.
- Actors involved and their role in the process:
- In order to create lighthouse projects, it is extremely important that the right actors come together. First of all: the architect with the concept, Volkswohnung with the need and willingness to try out the concept, and the state of BW with the funding that made it possible to make the project circular and relocatable.
The right specialist planners are also important, especially structural planning.
