A PLACE IN THE SUN
Aerin Lauder, a beauty executive, rides her Hermès bike wearing her late grandmother’s straw hat at her East Hampton home.

THE BIG CHILL
The pool house takes inspiration from Babe Paley’s Round Hill retreat.

MY BLUE HEAVEN
Lauder collaborated with Donald Kaufman on the teal paint in the dining room. A Waterford chandelier illuminates an 1840s Indian-colonial table with a marble top. The mirror above the fireplace and the chairs once belonged to her grandmother, Estée.

OLD HAT
Estée’s hat collection is displayed in the powder room.

GOOD SPORT
The mudroom reflects the family’s active lifestyle, with the boys’ sports gear, wetsuits, and vibrant artwork on display.

A 1962 Mercedes sits parked out front.

PICTURE PERFECT
Upstairs, a Tina Barney photograph of Aerin and her sons hangs in the sitting room, which features batik fabrics by renowned New York designer Mark Hampton.
