What Polhemus Savery DaSilva does

Polhemus Savery DaSilva (PSD, operating as PSD Architects & Builders) is a privately held, Massachusetts-incorporated architecture and construction firm founded in 1996 and headquartered at 157 Route 137, East Harwich, MA. The firm delivers fully integrated architecture and construction services for affluent private residential clients across Cape Cod and the broader New England region, with a secondary portfolio of hospitality, civic, and museum work. Its practice centers on a coordinated design-build methodology that carries each project from site selection through architectural design, construction, fine craftsmanship, and ongoing post-completion property services.

The firm's core product is custom single-family residential architecture — including Seaside, Saltwinds, Whalewatch, Dual Waters, and countryside projects — designed in a synthesis of modernism, Shingle Style, and Cape Cod vernacular tradition. Architectural design and construction labor are bundled under a single contracting entity, which differs from the prevailing model of separate architecture firms and general contractors in luxury residential. Notable technical components are limited to human-driven design expertise; there is no proprietary software product, no API, and no AI/ML tooling disclosed. Award-winning commercial work includes the Wequassett Resort Signature Collection, Pool Complex, Pro Shop, and Children's Center; the Cape Cod Museum of Art renovations; and the 2021 Bulfinch Award-winning Talcott Lodge restoration at Old Sandwich Golf Club. Recent additions to the offering include a solar pergola design-build delivered with renewable energy partner My Generation Energy and a published monograph, "The Art of Creating Houses."

PSD generates revenue under a professional-services model on a per-project basis for custom homes, renovations, additions, and select commercial commissions. Pricing is not publicly disclosed and varies materially by scope, materials, and site conditions. The go-to-market is sales-led and relationship-driven, relying on portfolio visibility through the firm's website (psdab.com), editorial coverage, industry awards, social media (Houzz, Instagram, Facebook, Pinterest), and word-of-mouth referrals among affluent Cape Cod and New England clients. The firm employs 11–50 staff, operates from a single office, has no parent company or subsidiaries, and is not venture-backed.
