A view of the house from the pool illustrates the architecture’s complex hexagonal geometries.

The real triumph of Rottet’s reimagining lies in the architect’s ability to honor the house’s midcentury roots while simultaneously infusing the home with a vivid contemporary spirit. Neither aggressively decorated (with a capital D) nor casually tossed together in the eclectic beach style so prevalent in the Hamptons, the home’s myriad hexagonal spaces pay homage to Nelson and Chadwick’s vision as well as the current owner’s gutsy, wide-ranging sensibility and incisive eye.

Original banquettes, bookcases, and other striking architectural details—notably the handsome floor-to-ceiling screen that defines the dining room—all mingle amicably with an array of vintage furnishings by such midcentury masters as Raymond Loewy, Franco Albini, and Paul McCobb; contemporary pieces designed by Rottet herself; and an art collection that boasts signature works by the likes of Larry Poons, Alexander Calder, and Kiki Smith. A classic Marshmallow sofa, designed by Nelson and his associate Irving Harper in 1956, naturally has pride of place in the living room.

“I can always find a spot for the things I love,” Rottet says of her generous but measured approach. “That’s the beauty of this incredible house. It has a foot in the past but it definitely celebrates the present and future. It’s living architecture.”
