A couple commissioned architect and designer William T. Georgis to renovate the nearly century-old Colonial Revival, situated in the village of Southampton, in just a handful of months. The stand-alone living room at left was a later addition to the original structure.

Isamu Noguchi paper lanterns stained by William T. Georgis hang above a variety of seating in the living room, anchored at the center by a large custom-made Georgis & Mirgorodsky ottoman. Galerie Maison et Jardin bamboo armchairs mingle with a vintage glass-top Sputnik table, while a pair of 1970s Milo Baughman sofas face off next to the fireplace. Midcentury hurricane sconces from L’Art de Vivre flank the Andy Warhol portrait of Grace Kelly above the Louis XVI–style mantelpiece, and the rug is by Patterson Flynn Martin.

A Julian Schnabel work in a Southampton home designed by Georgis & Mirgorodsky.

Creating a sophisticated mix of styles and textures in the dining room, Georgis installed 19th-century Chinese lanterns fashioned of rosewood and marble above the custom-made table in powder-coated steel and Eero Saarinen chairs with a fiberglass seat; curtains in a wood-grain-pattern fabric by Brunschwig & Fils frame the vintage Edward Wormley sideboard, and the painting is by Julian Schnabel.

Another Schnabel painting presides over the media room, where faux-marble panels conceal the television mounted above a custom-made cabinet; Georgis & Mirgorodsky also designed the sofa, the barrel-back chairs are by Milo Baughman, the tray and faux-bamboo stand are 19th century, the vintage lamp is by AH Kag Switzerland, and the rug is by Rosemary Hallgarten from ALT for Living.

In a guest room, a Hinson stripe serves as the backdrop for family portraits; Georgis & Mirgorodsky designed the bed, which is upholstered in Frette fabric and draped with a coverlet made from an antique Japanese monk’s robe, while the curtains are of a Kravet fabric and the rug is by Stark.

A Mattias Stenberg lamp perches on a Missoni side table near the bedroom’s window seat, where 19th-century insect exhibition cases are displayed.

Clad entirely in Carrara marble, the main bath is outfitted with a Waterworks tub and fixtures as well as a table from Mecox Gardens.

Georgis added a covered terrace at the back of the house, overlooking the pool.
