You can only place swg credits, you guessed it, Decorations.
In the Control Room, you can place Control items in addition to the standard decoration. In the Power Room, you can place Generators and Cir-cut Breakers. In Decorative Rooms, you can only place swg credits, you guessed it, Decorations. Some rooms that can be built are Defensive in nature, and allow you to place a Defense Item. If you plan on Raiding, you best be thinking about getting at least one of those! Nothing says "Surprise!" like a Turret in the Control Room! The final button is Current Room, and it gives a listing of all the items in the room! That makes it easier to mass sell things, or if you need to select that tiny phone or stack of papers to move it. Pretty useful for selling items and finding where they are.
