Price: $15.9 million
Listing agent: Suzanne Perkins, Sotheby's International Realty, 805-969-9993
Located on 3.5 acres in Santa Monica's tony Montecito district, this 2-year-old modernist house includes an art gallery the owner uses to display his vintage-car collection.
With polished floors, walnut-lined walls, museum-quality lighting and enough space for 32 vehicles, the gallery holds classic cars from Mercedes, Ferrari and other super-premium brands. A huge Mobil "winged-horse" logo adorns the wall, while huge glass windows make the collection visible from the outside.
The Glass Pavilion also features five bedrooms, 5.5 bathrooms and a massive wine room -- all surrounded by superclear Star Fire glass, more typically used for jewelry-display cases. Learn more about the house here.
