Maxvorstadt R11 is a minimalist roof extension located in Munich, Germany, designed by Pool Leber Architekten.

The foundations of the existing 1980s building had limited carrying capacity and did not allow for a simple extension of this size. Instead, it was first necessary to demolish the reinforced concrete structure on the fourth floor before extending upwards with more lightweight construction. The new structure of massive timber, clad in steel encloses two new floors and a mezzanine gallery. In total, three separate living units have been created.
