The main building has a kitchen/dining area and a living room and bathroom. Upstairs is a bedroom that belonged to the 7 dwarves and therefore it is pretty spacious. After Snow White moved in the dwarves packed their little beds and bags and moved into one of the rooms of the Old Mine. The Old Mine has the musical room (I think in the original Walt Disney film there is a scene where the dwarves play the piano and Snow White dances) and an upstairs single bedroom. Downstairs is the bedroom of the 7 dwarves and from there you can also reach the mine and working place of the 7 dwarves.
