Cass Calder Smith Architecture + Interiors

About

Cass Calder Smith Architecture + Interiors is a design studio grounded in the belief that architecture should feel enduring, personal, and deeply connected to place. Founded by Cass Calder Smith, the firm creates residences, hotels, and restaurants that balance modern clarity with warmth, material richness, and livability. Projects include homes in the Hamptons, New York City, California, and abroad.

The work is shaped through close collaboration with clients over many years, with an emphasis on thoughtful proportion, natural light, an attention to details, and the expressive qualities of materials. Each project is approached as a unique response to site, program, and the way people live, resulting in architecture that is both refined and quietly timeless.
