Stephen Kelleher Architects

What Stephen Kelleher Architects does

Stephen Kelleher Architects, Inc. is a privately held, full-service architecture firm founded in 1990 by Stephen L. Kelleher, AIA, and headquartered at 57 Alden Road in Fairhaven, Massachusetts. The firm operates as a five-professional corporation delivering architectural design, feasibility studies, planning, programming, 3D visualization, accessibility (ADA) compliance, historic preservation and adaptive reuse, green energy design, building and zoning code compliance, and construction administration. Its core technology is computer-aided design with 3D modeling and file-sharing capability across consultants and collaborators; there is no proprietary software platform. Services are delivered on a project-based professional services model with no publicly disclosed pricing. Customer segments are broad and horizontal: single homeowners, small businesses, large corporations, religious and educational institutions, industrial firms, and municipal and state agencies across southeastern Massachusetts and Cape Cod. The firm holds Registered Architect licensure in Massachusetts and Rhode Island and a Massachusetts Licensed Construction Supervisor certification.

The firm has built domain specialization in historic preservation, coastal and flood-zone construction, and green energy design — the latter delivered in part through its wholly-owned subsidiary kWind, Inc. Notable commissions include the Carlson Orchard 220 kW solar array (described in 2010 as the largest agricultural solar installation in Massachusetts), the Sylvan Nursery 10 kW Bergey wind turbine, multiple housing authority and Department of Conservation and Recreation projects, the 2021 Swansea Waterfront Revitalization Phase One, and the 2022 Veridian Condominium Complex (140 units) in Plymouth. Geographic reach spans approximately 15 southeastern Massachusetts and Cape Cod communities, and the firm maintains an active Facebook presence and a portfolio-driven website. Ownership is independent with no parent company or institutional investors, and revenue is undisclosed.

Direct peers

• Margulies Perruzzi Architects: Boston-based mid-size commercial and institutional architecture firm of comparable scale, serving similar New England corporate, life-sciences, and public-sector clients with full design services. Directly comparable as a regional professional services peer competing for the same enterprise and institutional RFPs SKA targets.
• Bargmann Hendrie + Archetype: Mid-size Boston architecture firm offering adaptive reuse, historic preservation, and commercial design — overlapping significantly with SKA's service portfolio. Comparable in scale and in the types of New England institutional and developer clients it pursues.
• William Rawn Associates: Boston-based firm delivering full architectural services across cultural, civic, and residential typologies — a comparable regional peer pursuing similar institutional and developer clients in New England.
• Bruner/Cott & Associates: Boston architecture firm of similar headcount with strong portfolio in adaptive reuse, historic preservation, and residential/mixed-use projects across New England. Directly comparable regional peer with overlapping specialties.

• Sasaki Associates: Watertown, MA-based large planning, landscape architecture, and design firm. Much larger than SKA and broader in scope, but a relevant incumbent competing for institutional, campus, and waterfront master-planning work in the same New England geography.
