The architecture and planning sector in New York features a mix of well-established global firms and younger companies. These firms primarily focus on designing buildings and spaces, offering comprehensive services that often include engineering, planning, and sustainability consulting. Many emphasize innovative solutions and contextual sensitivity in their projects. Notable firms include HOK, a global firm offering design, architecture, engineering, and planning services, and Skidmore, Owings & Merrill (SOM), recognized for environmentally-advanced solutions. KPF designs diverse, innovative buildings globally, while Perkins Eastman focuses on creating a positive impact through progressive design.
A common thread among these New York-based companies is their commitment to creating impactful and thoughtfully designed environments. Firms like WORKac focus on public, cultural, and civic projects with social and environmental concerns, and Rockwell Group merges performance and architecture to create extraordinary experiences. The data shows a strong presence of firms founded between the 1930s and 1980s, indicating a long-standing tradition of architectural excellence in the city, alongside newer entrants like particular, specializing in steel curtain walls.

How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
