Go check this proggy out. Awesome for the price. I got IMSI turbocad 7 and FP 6 in a package at compusa last summer for about $50. You can build literally any kind of house and decorate any room. Tons of model choices, tons of custom building objects. Exports in grouped three axes 3d formats. Bryce lets you select textures for any group (ie glass for windows, wood for doors, etc). You can build very easily and if you're online with the program, it has tons of tuts and dl's that are integrated into the interface.
