What S9 Architecture does
S9 Architecture is a New York City-based architecture and engineering firm organized as a Design Professional Corporation, founded in 2011 and led by five principals supported by a 60-person design team. The firm delivers three integrated services — architecture, interior design, and master planning — guided by an explicit design philosophy the firm describes as "modern contextualism." Its portfolio is anchored in large-scale adaptive reuse and mixed-use developments, including some of the largest industrial-to-mixed-use conversions in the United States: Industry City (6.5M SF, Brooklyn), Ponce City Market (1.3M SF, Atlanta), and Camp North End (Charlotte), alongside residential, civic, and institutional projects.
The firm's customer base is concentrated among institutional-grade real estate developers and select nonprofit and institutional clients, including Toll Brothers, Jamestown Properties, Boston Properties, Hines, Rudin, L+M Development Partners, Domain Companies, Steiner NYC, the Cleveland Foundation, and The Browning School. Revenue is generated through project-based design fees tied to individual developments, with several developer clients engaging S9 across multiple projects over time. Engagement scope ranges from master planning for multi-million-square-foot campuses to mid-rise residential and interior fit-out commissions.
S9 has expanded geographically from its NYC base to a footprint spanning the Eastern U.S. — including Atlanta, Charlotte, Nashville, Raleigh, Tampa, Boston, and Washington, D.C. — and into Toronto, while broadening into adjacent verticals such as large-scale affordable housing (notably the 2,500-unit Willets Point development) and institutional / nonprofit work. There is no disclosed revenue, funding activity, M&A history, or proprietary AI/technology stack in the available record; the firm's value proposition is grounded in design talent, principal-led client relationships, and a referenceable portfolio of marquee adaptive reuse projects rather than in technology differentiation.
