The architecture and planning firms in New York State are a mix of large, established companies and younger firms, many of them based in New York City. HOK, founded in 1955, offers design, architecture, engineering, and planning services. Skidmore, Owings & Merrill (SOM), established in 1936, focuses on environmentally-advanced design solutions.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
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 13, 2026.
