Mabbott Seidel Architecture is a design practice that provides full architectural, project management, and interior design services. We specialize in creating finely detailed residences, including the design and fabrication of custom millwork and furniture. Our projects include new construction and adaptive reuse within New York City, Long Island, and elsewhere. We strongly believe that the genesis of a successful project is in the close interaction of client and architect during the design process and is realized in partnership with the team of craftspeople MSa has fostered over many successful years.
