Hill West Architects LLP is a New York City-based architecture and planning firm founded in 2008-2009, organized as a privately held limited liability partnership. The firm specializes in high-rise luxury residential architecture, providing design architect, executive architect, and architect of record services on large-scale condominium, rental, and mixed-use developments throughout New York City, including Manhattan, Brooklyn, Queens, and the Bronx. Its project portfolio includes multi-million-square-foot developments such as Waterline Square (2,266,822 GSF, 1,134 units) on the Upper West Side, Bankside (1,379 units) in the Bronx, the Riverside Center Master Plan (3,100,000 GSF across five buildings), Olympia (a 401-foot sail-shaped tower in DUMBO), One West End, and The Rockwell.

The firm's underlying technology platform is built on Building Information Modeling (BIM) using the Autodesk Software Suite, including Revit, Navisworks, and the BIM360 Design Suite, with documented BIM coordination and QA/QC standards applied across project delivery. Its proprietary design expertise is evidenced by complex, award-winning building forms such as the sail-shaped Olympia facade engineered around NYC sky exposure plane regulations, and a growing capability in sustainable design spanning LEED Silver certifications and the firm's first Passive House project, Gemma Gramercy. The firm holds multiple American Architecture Awards, a 2020 Multifamily Project of the Year, and consistent industry rankings from BD+C and Crain's.

Hill West's revenue model is professional services fees on development projects, with a sales-led go-to-market motion driven by direct business development with real estate developers and property groups. Customer relationships are concentrated among a small set of high-end enterprise developers, including GID Development Group, Brookfield Properties, Fortis Property Group, Silverstein Properties, Toll Brothers City Living, and El Ad Group. The firm has 101-250 employees, operates from a single headquarters at 11 Broadway in Lower Manhattan, and runs with no disclosed external funding or parent company, reflecting a partner-owned professional services model.
