STEP
BFK Architekten prepared an urban planning study for the western “STEP” development area in Stuttgart-Vaihingen.
The plans called for a total of five buildings, all based on the same design concept. Each floor is organized around a central, multi-story staircase hall and contains up to four rental units. Their flexible sizes allow for rental spaces ranging from approximately 100 to 1,000 square meters.
The first building, “STEP 8.1,” was completed in 2008.
The building is highly articulated, responding to the constraints imposed by the existing buildings and the pedestrian connection to the adjacent Gropiusplatz. This central square within the “STEP” development, with its “stone-like” character, is complemented by the appealing terraced landscaped area of “STEP 8.1.” The façade design, featuring window bands of varying lengths and light-colored rendered surfaces, follows the sculptural concept of the overall design.

The second building in “Group 8” is virtually identical in design. However, it pursued particularly ambitious ecological and sustainability goals. From the outset, DGNB certification was targeted, and the planning and construction were carried out accordingly.
Key features of the concept include:
- Gas condensing boiler with combined heat and power generation
- Emission-free and solvent-free surface materials
- Daylight management systems
- Direct and indirect lighting with individual workstation controls and more
“STEP 8.2” was completed in 2010 and received DGNB Gold certification.
The two buildings “STEP 7.1” and “STEP 7.2” were completed in spring 2015. They were also based on the same design concept, but featured a modified façade design. Both buildings received DGNB Gold certification.
The final building, “STEP 8.3,” was completed in 2018.
