I want to place a house with the door going a certain direction. Any tips from you professionals out there?

Also, I have a medium naboo and want to drop stuff on the stairs and move it over on tables, etc. Will it let me move stuff this way into the second room or can I really only do it in the big atrium area?

What are the commands for floating stuff over?

Thanks for your help, oh wise and all-knowing architects!
