Atelier – Heyman Hamilton [AT–HH] is a collaborative architecture practice working with private owners, investors, builders, community organizations, and artists, providing support for projects at any or every stage—from feasibility studies and design development to permits and construction documentation for renovations, additions, and new builds.
While we work across a wide range of project types, we have a strong focus on adaptive reuse: transforming existing spaces to meet new arrangements and standards. We see potential in both the overlooked and the celebrated, tailoring each process to our clients’ unique needs.
With experience in Sweden, Switzerland, and New York, our practice brings material sensitivity, care, and flexibility to every project.
Wherever you are in your process, we’ll help you find the best way forward.
