Location: Del Mar, California

Price: $26,500,000

Just steps from the sand in Del Mar, California, this Mediterranean-style beach house was built by architect Bob Ray Offenhauser for none other than Colleen Knapp, the founder of Architectural Digest. The half-acre compound, dubbed Seven Arches, measures some 6,550 square feet, with, as you might have guessed, seven arches, all arranged around the swimming pool, five bedrooms, a two-story great room, media room, gym, and gourmet kitchen. Picking up the former home of the "international design authority" founder was never going to be a cheap proposition, but is $26,500,000 a terribly steep price to pay for a pink castle on the sand?
