Awaiting personal finishes, a brand-new, custom Contemporary-style 10-bedroom, 12-bathroom Bridgehampton home is on the market for $43 million.

The more than 15,000-square-foot white brick, glass and cedar shingle estate fronting Sagaponack Pond is expected to be completed by summer. It is on more than three acres and includes a separately deeded 1.8-plus-acre lot.

"One of the nice things about walking into this and buying a custom house is that it usually takes a good two years to get all the permits and plans in place before even starting to build a waterfront home," says listing agent Diane Saatchi of Saunders & Associates.

Floor-to-ceiling windows on both floors of the main home offer views of a sprawling lawn, Sagaponack Pond and the farm fields beyond.

Imagine a home with every conceivable amenity: Timothy Haynes architecture, three fireplaces, all-weather tennis court, 1,800-bottle wine cave, pool house, heated gunite pool and hot tub and a four-car garage for starters. A private two-story wing accommodates guests, a gym above the garage features Hamptons views and art can be safely stored in a designated, temperature-controlled storage room.

The master suite features double baths, walk-in closets and dressing rooms, a sitting room/office and a private terrace overlooking the pond. Three additional bedroom suites complete the second floor.
