Thiel Architecture + Design



We believe a good life starts with good design. A thoughtful layout. Fluid circulation. Well-proportioned spaces. Abundant storage. Beautiful details. Wonderful views. And smart, solid construction.  


Our design approach focuses on our clients and how to enhance their experience as they move through and interact with objects and their surroundings. Micro and macro, this approach is centered on the user experience. While most of our clients are building in the Greater New York City area (e.g., Westchester County, Fairfield County, Manhattan and Brooklyn, New York, and northern New Jersey), we offer our design services for wherever you wish to build.

Our experienced staff uses their architectural, interior design and industrial design know-how to find the best design solutions. The team has the ability to work across a variety of different project types from residential to hospitality, retail to contract. Our firm is recognized for our dynamic and collaborative process.
