Check out these select highlights from Season 4 of HGTV's Extreme Homes where art is the theme -- and where the houses themselves become art. Included: the "Four-in-One" house divided into party, privacy, art and guest quarters; the beach-side "Spider in the Sand" house and a hillside home in Spain that faces out in seven different directions.
On HGTV's Home Strange Home, step inside some decidedly different residences and see how visionary homeowners lived out their dreams and fantasies in the offbeat homes they created — including a fantastical artist's playground, an homage to Never Land and this spaceship house in L.A.
