A Large Room Glass Dome can be installed on a Large Room, at great cost to hull strength.A ladder must be built to travel between the rooms. The roof of the bottom Large Room will be the floor of the top Large Room, and Alien Containments will stack like in Multipurpose Rooms. Ladders can be placed where ceiling tiles are located, so long as another Large Room is above the tile.Note that Partition Doors must be built onto existing Partitions. Partitions and Partition Doors can be built along the markings on the floor, as well as attached to walls at wall nodes.This arrangement works correctly physically, but causes the floor of the upper tank to render strangely. Alien Containments on adjacent floors can be built in a "stair step" configuration, sharing only one floor node.They do not hold extra creatures, however. Alien Containments built in the Large Room will be approximately twice the size of one built in a Multipurpose Room, taking up two floor nodes.

The four nodes of this kind are marked by large black tiles.

Bioreactors, Nuclear Reactors, and Alien Containments can be built on nodes in the center of the room.Water Filtration Machines can be built along the same wall nodes, taking up a small amount of floor space.If another Large Room or a Moonpool is placed parallel to the Large Room, it is possible to form a multiple connection.Modules other than Compartments will form a tiny corridor. The Large Room can be expanded with other modules from its ten wall nodes.They pop out from the room a small distance when built. Hatches can be built on the wall nodes.The Large Room has ten wall nodes on which room expansions can be built: the short walls each have one, and the long walls four.
