The task was to create additional lettable living space within the existing building structure while ensuring that the interventions remained economical. Besides modernising the shop floor, the former electrical engineering room was to be converted into an apartment, and the attic was to be refurbished for energy performance and converted into living space.

The existing fabric, the spatial conditions and the need for cost-efficient design placed particular demands on the development of the project. At the same time, the building had to be brought up to current energy and construction standards without affecting the existing structures unnecessarily.
