Architecture Research Office

What Architecture Research Office does

Architecture Research Office (ARO) is a Brooklyn-based architecture firm founded in 1993 that provides commissioned architectural design across educational, cultural, commercial, public, and residential sectors, with particular depth in higher education, K-12, performing arts, and adaptive reuse. The firm operates on a project-based professional services model, engaging institutional clients such as Rice University, Brown University, Riverdale Country School, Green-Wood Cemetery, The Flea Theater, the Mellon Foundation, and Knoll through direct commissions and selective local Architect of Record partnerships that extend ARO's geographic reach beyond the Northeast into Texas and the Pacific Northwest.

The firm's core technology is its research-driven design methodology, grounded in expertise in sustainable construction systems including LEED, Passive House, WELL, mass timber, and SITES standards, with documented outcomes such as a 70%+ reduction in embodied carbon via hybrid mass timber and the first NYC public school built to Passive House standards. ARO supplements project fees with a proprietary product line — the ARO Collection of acoustic felt finishes (Block, Plank, Grid, Attach, Baffle, Arc, Array, Shingle, Fold, Divide) — developed and manufactured in partnership with Spinneybeck | FilzFelt and distributed through Knoll's national showroom network.

ARO is led by three principals (Stephen Cassell, Adam Yarinsky, Kim Yao) supported by a finance director, business strategy director, studio director, and project directors, totaling 11-50 employees. The firm monetizes through two streams: professional services fees for commissioned architectural work and licensing/royalty revenue from the ARO Collection. Marketing is conducted primarily through earned media in architectural press, AIA and NYCxDesign awards, academic lectures, and a 2024 Princeton Architectural Press monograph, with no disclosed external funding or private equity ownership.
