Our moon base has two greenhouses. They are connected with two laboratories. You enter through the green door. The laboratories have solar panels on top. There´s also a water tank with tubes (the red ones) to distribute it around the greenhouses and the rooms.
The rooms are underground. There´s a kitchen/dining room, a bathroom and a bedroom. They are connected by hallways (the purple tubes). To go down to the rooms there´s a lift.
