Set among mature trees in Sag Harbor, this 1986 residence by architect David Markolf is defined by sculptural white volumes, curved walls, and stacked vertical glazing. While the architecture remained intact, the interiors had not been updated since completion. We were engaged to rework the 2,593-square-foot home into a refined yet livable family retreat.

The renovation added one bedroom and two bathrooms and reconfigured the layout to improve flow and connection between spaces. A central move was removing the soffit between the kitchen and double-height living room, opening sightlines to the pool and garden and creating a more integrated main floor.

The brief called for a calm, neutral foundation layered with moments of color and personality. In the kitchen, custom oak cabinetry with rounded pulls is paired with durable porcelain waterfall counters and a polished chrome chandelier, balancing warmth and graphic clarity. Throughout the living spaces, we simplified key architectural elements — replacing the rose quartz fireplace with a white marble surround — and layered sculptural furniture, custom rugs, and curated artwork to add depth without visual noise.

Artwork plays a defining role, particularly in the dining room and study, where bold pieces are set against custom oak millwork and curved built-ins that echo the home’s original geometry.

In the primary suite, natural materials and an oversized skylight bring softness and light. Guest and children’s rooms introduce restrained accents of color, while maintaining cohesion through oak, stone, and layered textiles.

The result is a modernist home updated for contemporary family life — calm at its core, thoughtfully detailed, and respectful of its original architecture.
