After three years as chief architect at Bally, David Marquardt left to establish MACH Architecture. However, his association with the Swiss luxury shoe manufacturer continued when Bally commissioned MACH to design its new headquarters in Ticino and its groundbreaking concept store in Berlin.

Over the next four years, MACH designed three new concepts for Bally. The MACH team also planned and managed the successful concept roll-out in 150 Bally stores worldwide.
