The building (1) has lower and upper round sliding rails rotationally fixed to respective upper and lower supporting structures of corresponding building lower and upper parts (2, 3). The lower round sliding rail is formed in U-shape with lateral guiding rails, which are positioned upwardly, where ball shaped-rolling bodies are received between the guiding rails. The upper round sliding rail is supported on the guiding rails. The building upper part is rotatably supported on the building lower part and is formed as a top floor with a pitch roof. |
