Olbrich's own house was relatively cheap at 75,000 Mark. The building had a red hip roof that continued down over the ground floor on the northern side. Olbrich himself had also designed the entire interior. The house was heavily damaged in World War II. It was rebuilt in 1950-1951, although everything above the ground floor was completely changed. Only the white and blue tiles on the facade recall the original construction. It was used by the German Polish Institute from 1980 onwards.
