Designed by Breuer and his assistant Gustav Hassenpflug for the Berlin Bauausstellung in 1931, the House for a Sportsman combined a fitness club with a residence for a gymnastics teacher. The house consisted of a large training room off of which opened five small rooms, which could be closed off from the main space by accordion doors. The five rooms contained a dressing room, bathroom, bedroom, study and dining room. One corner of the training room also served as a living room with thick cushions serving as a make-shift couch. The kitchen, guest room and second bathroom were separated from the rest of the house and not included in the full-size installation created for the exhibition. Breuer furnished the apartment with Thonet tubular steel furniture and bookshelves and wall units of his own design. Like the Piscator Apartment and the House for a Gymnastics Teacher, this exhibition revealed the contemporary obsession with health and the connection between modernism and hygiene.
