Architect Peter Cook is known for his Hamptons design work, but his latest project will be for himself. Cook recently purchased a new home in Sag Harbor for $2.175 million, with plans to renovate.

The three-bedroom ranch sits on the water and has a dock and views of Sag Harbor Bay. It’s three houses away from Cook’s previous home, which he had sold before the new one came on the market.

“I look for something with room to grow, room to improve,” says Cook, ex-husband of supermodel Christie Brinkley.

The home has a wraparound deck and an outdoor shower.

It had been listed with Mala Sander of The Corcoran Group.
