Situated on a narrow two-acre waterfront site in Sag Harbor, this Hollywood Regency–style summer home draws inspiration from the Coral Casino in Santa Barbara and a John Staub house in Houston. Features include long terraces, an expansive loggia, and a lighthouse-like octagonal tower. Inside, soaring spaces—like the double-height bath and clerestory-lit living room—balance glamour with restraint. A circular pool, guest house, tennis court, and native plantings complete the landscape design. The finishes and furnishings were done by architect and designer Daniel Romualdez.
