Based in the Hamptons with projects that extend across the U.S. and internationally, Hilary Madigan is a bespoke Interior Design firm known for crafting interiors that quietly defy convention. The firm brings an intuitive, deeply personal approach to each project—whether reimagining a coastal retreat or curating the layers of a storied estate.

Our philosophy is a mix of vision, personality, and experience that results in spaces that feel both transcendent and grounded. Every project is a portrait—not just of a place, but of the people who live there.
