Castles aren't all about moats and dragons: This desert castle is made of adobe and powered by solar panels and wind energy. While the castle might break all the storybook rules, it's still worthy of royalty. The home has Craftsman details throughout, from the handmade, tin-punch cabinets in the kitchen to the custom tile artwork in the doorways. There's also an amazing post-and-beam ceiling and a tile floor throughout the home.

The castle can be entirely run on alternative energy. Solar panels and a wind generator power the house, and a grey water system provides sustenance for the desert garden.
