A gingham cushion on a mahogany early Empire-style settee provides a preview of the fresh updates integrated throughout the Kirschner home.

To complement the green colorings that are prominent around the house, ivy-embroidered sheers filter the light streaming in through the large window in the library.

Old family silver serving pieces mix comfortably with a silver Edwardian punch bowl.

In the entry hall gallery that wraps the inside perimeter of the house, an antique, carved library table is flanked by matching Chippendale chairs and guarded by a pair of ceramic Chinese Foo Dogs. Much of the furniture in the house was acquired during trips to auction houses in New York, Connecticut, and Florida. Floors throughout the gallery are antiqued limestone.

An antique Pembroke table at a kitchen window is a lovely spot for a morning cup of coffee and for organizing the day. The green cupboard holds some of Gloria’s glass and pewter collection.

Anchored by a needlepoint rug purchased at an auction, the master bedroom showcases a focal-point four-poster updated with a fresh coat of white paint. Sage green painted walls complete the look.

The guest bedroom proudly wears a hand-blocked floral linen on the walls. It’s a bold touch that imbues the room with vibrancy and offers a change of pace from the more soft-spoken downstairs spaces. “In this bedroom, it almost feels like you are stepping into a painting,” says Fhillips. “It has a kick that departs from the rest of the softness.”

The railing of this spectacular staircase at the back of the house recalls Gothic architecture.

The cushion fabric shows homeowner Gloria Kirschner’s love of the Hamptons’ signature hydrangeas.

The pool house, reflected in the water, features teak furniture from Indonesia.
