The Sims Cheats

Outside Stuff Inside
Normally you can't put something say a basketball hoop inside your house. To get pass this you simply build the room that you want to put the item in BUT leave a section out of it. The game won't read it as a room so you are still free to put outside things inside of it.

OTHER OPTION: Buy all of the things for your Sims home first and then build your house around it.
