The best part about owning your own home isn't the satisfaction you get from knowing that you can provide for yourself and your loved ones... it's knowing that you can do whatever you want to it. If you have room in the back yard, you should seriously consider building any of the things on this list. Your inner child will thank you when you're spending time in your custom-built pirate ship and throwing water balloons at your neighbors.

6.) A treehouse that tops most houses: The house Steve and Jeri Wakefield built for their grandsons has a zipline, climbing wall and slide. So jealous.
7.) A treehouse inspired by Dr. Seuss: Seuss was a dangerous architect, so you might have to tone down his houses a little.
8.) A personal Hobbit house: Architect Peter Archer built this for a big J.R.R. Tolkein fan. Totally worth it.
