Hajian Architects

What Hajian Architects does

Hajian Architects Inc. is a full-service architectural firm headquartered at 29 Williams Street in Watertown, Massachusetts, with architectural registrations in six U.S. states (MA, RI, CT, NH, NY, NM). The firm is privately held and co-led by brothers Paul Hajian (MIT) and David Hajian (Rhode Island School of Design), each a licensed architect with more than 25 years of experience. The firm employs between 11 and 50 people and has completed hundreds of projects across the New England region for both public and private sector clients.

The firm's practice spans four primary service lines: residential architecture (single-family houses, renovations, additions, ADU design and filing, fire reconstruction); religious and educational architecture (synagogues, schools, churches, community mikvahs, with specialized capabilities including mechitza and Ark design); commercial architecture (retail fitouts, restaurants, office renovation, adaptive reuse); and historical preservation (renovation of historic structures in coordination with historic commissions). The firm also offers zoning and variance/special permit filings as an add-on service and conducts pro bono planning studies and community design projects for schools and religious institutions.

Revenue is generated through project-based professional services fees tied to design, planning, project management, and consulting. Pricing is quote-based and not publicly disclosed. Go-to-market is sales-led and relationship-driven, relying on direct client engagement, referrals, and the firm's professional reputation in the New England market. The firm uses its Wix-hosted website portfolio and a LinkedIn presence (David Hajian) as its primary marketing channels. There is no evidence of external institutional investment, M&A activity, parent-subsidiary structure, or non-architectural product offerings.
