What Bates Masi Architects does
Bates Masi + Architects LLC is a privately held, full-service architectural firm founded in 1967 by Harry Bates and headquartered in East Hampton, New York with a second office in Midtown Manhattan (21 West 46th Street). The firm serves high-net-worth residential clients in premier locations including the Hamptons, East End Long Island, and New York City, alongside commercial and hospitality clients across both domestic and international markets. Its services span custom residential architecture, commercial architecture (offices, hotels, restaurants), and bespoke furniture design produced in an in-house wood shop. The firm operates under a project-based professional services revenue model, with custom architectural fees per engagement and direct client inquiry as the primary go-to-market channel.
The firm's competitive positioning rests on a research-driven design methodology emphasizing material exploration, craft, and environmental response, paired with six decades of operating history and a recognized founder legacy in midcentury modernism. Current leadership comprises four principals: Paul Masi (Harvard GSD, ex-Richard Meier & Partners), Aaron Weil (UVA, ex-William McDonough + Partners), Aaron Zalneraitis (Cornell), and Katherine Dalene Weil (RISD). The firm has accumulated more than 260 design awards since 2003, published two monographs (Bespoke Home in 2019, Architecture of Place in 2023), and maintains sustained earned media presence in Architectural Record, Interior Design, the New York Times, Architectural Digest, and Forbes. Notable hospitality work includes the ASSET Restaurant in Sag Harbor and Tessa Restaurant; residential portfolio centers on coastal Long Island projects including Walking Dunes, Three Mile Harbor, Mohegan Trail, Wainscott, Shinnecock, and Signal Hill.
