Arckit Architectural Model System
Sure, you could build your home designs out of blocks procured from the local toy store. But if you're wanting to get serious about showing off your architect skills, perhaps you should graduate to the Arckit Architectural Model System. This building tool uses a variety of interconnecting components to represent floors, walls, windows, doorways, stairs, roofs, and pretty much any other architectural feature you could imagine, all of which snap together without any glue or tools required. You can also apply textures and finishes like wood, tile, and stone via adhesive sheets, and like any good building system, it's just as easy to rip it apart and start over again.
