Where can I find 3D house design software?

You know, it lets you design a house with 3D objects and put furniture and other things in it. Prefferably on where you can put support beams and such in as you would see in a real house. (Like in the attic.) But anything will help. I don't have a lot of money so a free program would really be appreciated. Again, any program would help. Thanks
