In an attractive inner‑city location in Karlsruhe, a modern residential development with affordable rental apartments was completed at Sommerstraße 1, combining urban living with contemporary residential comfort. A total of 1,611 m² of residential space was created, comprising 18 apartments in the front building and 2 additional units in the rear building, offering high‑quality living space particularly suited to students and young couples seeking a central location. The project is complemented by 20 comfortable underground parking spaces, providing each apartment with a separately rentable parking option.

Site & development potential
The Karlsruhe rental housing market is characterized by stable demand and attractive conditions for sustainable residential concepts. The centrally located yet residential setting of Sommerstraße is among the city’s most desirable residential areas in the city. Karlsruhe Palace Garden "Schlosspark" and the city center can be reached within minutes by bicycle, car, or public transportation. The nearby Ludwig‑Erhard‑Allee directly connects the southern part of the city with the western districts, highlighting the site’s excellent transport connectivity.
Architecture & usage concept
As part of a revised planning process, the design was strategically optimized to increase the floor area ratio and make efficient use of the site. This optimization significantly improved the project’s economic performance. The resulting usage concept combines compact, functional floor plans with a sustainable approach and contributed decisively to the successful completion of the development.
