This was an environment design project completed in my second year at Manchester Metropolitan. The concept was a cafe that served as the player's base and the fast travel system of the game, taking you to set locations within towns and cities and acting as a cafe to the general public.
The cafe featured cogs on the outside that operated the pulley mechanism to open the roof, allowing the hot air balloon to inflate and carry the cafe away. They didn't require much staff as the waiter was a tea train that went around the cafe.
