Selldorf Architects

What Selldorf Architects does

Selldorf Architects is a New York-based, founder-owned architecture firm established in 1988 by Annabelle Selldorf. The practice operates as a private professional services firm with 101–250 employees and a single headquarters at 632 Broadway in Manhattan, serving institutional and private clients globally across cultural, residential, and commercial projects.

The firm provides full-service architectural design — including new construction, renovation, expansion, adaptive reuse, and interior design — for marquee cultural institutions (museums, galleries, libraries), select high-end residential clients, and commercial enterprises (notably art galleries and cultural venues). Its core technology is a documented "humanist design philosophy" emphasizing individual experience and sensitive integration with existing context, exemplified in completed and ongoing flagship projects including The Frick Collection (completed April 2025), the National Gallery London's Sainsbury Wing (completed May 2025), the Hirshhorn Museum revitalization (jointly with SOM), the Art Gallery of Ontario expansion (jointly with Diamond Schmitt and Two Row Architect), and the €1.15 billion Louvre-Nouvelle Renaissance project (jointly with STUDIOS Architecture Paris and BASE Paysagiste), won in May 2026 after a competitive process from over 100 candidates.

Revenue is generated through project-based professional services fees negotiated individually for each commission, typically on multi-year contract structures tied to construction budgets of marquee institutional clients. The firm has no public listing, no disclosed funding rounds, and no identified institutional investors; ownership remains concentrated with the founder. Distribution relies on direct enterprise engagement via invited competitions (for public cultural institutions), peer referrals, and reputational selection by private clients. Marketing is largely passive — earned media in Architectural Digest, WSJ, NYT, and Architectural Record; awards; and principal lectures at Harvard GSD, Columbia GSAPP, and the National Gallery London. Beyond commissioned services, the firm operates the "Vica by Annabelle Selldorf" sub-brand — a consumer product line of furniture, textiles, accessories, and lighting — with a dedicated showroom opened in March 2026 at the New York Design Center.
