Software Recommendation For Room Design?

I used Punch! Architectural 3000 (I got it for about $40). It worked well, but Google's Sketchup is an excellent tool. The Punch! products allow the generation of material lists.

Free AutoCAD clone. Don't bother though unless you already speak AutoCAD. Your time is better spent building stuff than learning convoluted software.

Have a look at this guy's design. If you like it, the free program is from SweetHome3D. As opposed to a general purpose graphics tool like SketchUp, this is aimed at room/home designs. It's easy to learn.

But a lot depends on what level of detail and precision you want to include.
