The project goes over a usual office space and offers a new concept of working. The staircase, which is a modular system, becomes a living space that combines interior and exterior, “above” and “below”, sharing and individuality. The Cronoscala is a compromise between the teamworking and the necessity of a personal working space. The simple nature of the staircase and the modular structure generate new situations that bring to the different utilizations of the same place. So one has stairs for the teamworking and understairs for the personal study.
