The prisoner Erich Essner was occasionally doing gardening work in her private apartment at 6 Voit Street, München, as early as 1934. Other prisoners followed who had to do household tasks. Between 1937 and 1945, Schwester Pia had her house in Munich Oberhaching extensively renovated by concentration camp prisoners. The garden was redesigned and the place was generally cleaned up. A garage was built, together with an enclosed swimming pool and a bunker. The materials for this work came solely from Dachau. It seems she paid for a part of the materials, but she took the biggest part for free. In the workshops of the concentration camp the prisoners had to produce furniture, wood carvings, and children's toys for her.
