When architect Peter Cook designed this 10,000-square-foot East Hampton mansion, listed for $12.995 million, he kept the property in mind.

With a 17-acre protected natural area next door, there are plenty of “dazzling views” at one’s disposal, says listing agent Evan Kulman, of Compass Real Estate. One place to do that is in the six-bedroom, eight-bath home’s great room, complete with floor-to-ceiling windows.

“Peter wanted to bring the outside in. He did that with the walls of glass,” Kulman said.

Cook melds shelter and nature in other portions of the house as well. The master bedroom suite is designed with a wall of glass overlooking the property. An outdoor dining pavilion equipped with a screened-in dining area, an indoor fireplace and an outdoor fireplace on the opposite side — just two of the six fireplaces in the residence.

The Edmund Hollander-designed grounds include specimen trees, multiple patio areas and terraces, a heated infinity-edge pool, hot tub and pool house. An “extensive exterior lighting installation” was designed by Greg Yale, Kulman says.

Creature comforts include accents of hand-cut stone, walnut floors and custom cabinetry; a kitchen complete with built-in warming drawers and coffee equipment, and multiple dishwashers.

There is also a formal dining room, a large den or office and master suite with fireplace. The finished lower level offers additional living space, including a billiard room, media area and gym with separate sauna and steam room.
