The building has a bottom plate (6), and a roof (7) for stably covering a standard area (1) and an auxiliary area (1a) on the plate. Fixed side and rear walls (2, 3) enclose the standard area, and a movable side wall and a movable front wall (5) are provided for partially or completely extending the standard area around the auxiliary area below the roof. The fixed and movable walls are engaged into each other, and the movable walls are movable on rollers or rails. A support frame construction (8) retains the roof on the plate, where the construction and the plate form a constructive unit.
