An underwater-above water accommodation is adapted for human occupancy under water, above or on the surface of water and comprises an underwater accommodation (1) and above water accommodation (2) slidably mounted on preferably three, vertical legs (3, 4, 5). At least one vertical shaft (23) is fixed to the underwater accommodation (1), contains a lift (26) and stairs (28) inside and is slidably mounted in a sleeve (24) fixed to the above water accommodation (2). The underwater accommodation (1) has a pressure shell (12), in the lower part of which a first ballast tank (29) is located; the above water accommodation (2) has a structure (13), in the lower part of which a second ballast tank (30) is attached. At the sliding joint with the vertical legs (3, 4, 5) the underwater accommodation (1) has built-in sliding joint bushings (9, 10, 11) tightly linked to the pressure shell (12). At the sliding joint with vertical legs (3, 4, 5) the structure (13) is fixed to the sliding joint bushings (14, 15, 16). At least one rack (31) is attached to each vertical leg (3, 4, 5) and cooperates with a toothed wheel (32) being fixed to the structure (13) and driven by a drive unit (33); a drive wheel (49) is attached to the structure (13) and it is connected to a brake drum (50) and driven by a drive unit (52) via a disengagable clutch (51); a chain or a rope (44) is wound on the drive wheel (49) and the brake drum (50) is in contact with a brake pad (54), which is pressed against the brake drum (50) by a pad actuator (56), by means of a actuator lever (55).
