5. How about an oceanfront Art Deco compound designed to entertain on a grand, albeit expensive, scale?
Corcoran Group Real Estate

One of the East End’s most iconic estates, Four Fountains has had a long and fascinating history. In 1928, arts patron Lucien Tyng and his wife, Ethel, commissioned the firm Peabody, Wilson & Brown to design a venue for art exhibits, concerts, film screenings, fundraisers and performances on coveted Halsey Neck Lane in Southhampton, New York. Known for their traditional Colonial and Georgian Revival styles, Peabody, Wilson & Brown opted for an Art Deco aesthetic for the expansive arts center. Later, Archibald Brown, the architect who designed the building, acquired it along with his wife, Eleanor Brown, a leading interior designer and founder of McMillen Inc., America’s oldest interior design company. The home was subsequently purchased by CBS exec William Paley and his socialite wife Babe, who enlisted the one-and-only Sister Parish to re-design the home’s interiors. Today, the 9,000-square-foot, ten-bedroom estate is on the market for $35 million. The legendary home includes a main house, a caretaker's cottage, a greenhouse, a pool, and must-see grounds by the celebrated 20th century garden designer, Russell Page.
