Floor Planner

If you are thinking about redecorating (or just rearranging) your house or apartment, you should definitely check out Floor Planner. It's very easy to use and has better graphics than most floor planning software I've seen. The interface is straight forward. You just drag and drop walls, windows and other architectural elements to represent your room and then add contents from the 300+ furniture elements menu. Double clicking on different aspects of the room allow you to enter or alter dimensions. Oh, and it's free for personal use. (Found through Apartment Therapy).
