1. This David Adjaye-designed gem is currently owned by a major art dealer/collector.

This oceanfront residence was designed by the British architect, David Adjaye, for Adam Lindemann—a mega-dealer and collector, who founded New York and Los Angeles’ Venus galleries. The 7,500-square-foot, six-bedroom home features a traditional Shingle Style exterior and sleek, contemporary interiors complete with unique wood-lined floors, walls, and ceilings. The truly stunning retreat sits on over three acres at the tip of Long Island in Montauk.
