Designers


Studio 7.5 The group’s name, Studio 7.5, comes from an early idea to rent a 7.5-ton truck, put a model shop in it and drive from one project site to another. Obviously, freedom of movement is important for these designers. They move freely – and smartly – when designing products for their clients.
