What Frank Shirley Architects does
Frank Shirley Architects (FSA) is a boutique residential architecture firm founded in 2000 by Frank Shirley and headquartered at 40 Pearl Street in Cambridge, Massachusetts. The firm employs six named professionals and provides architectural design services focused on high-end residential new construction, additions and renovations, historic restoration and preservation, interior architecture, and consultations. Over its 25-year history, FSA has completed more than 150 additions and renovations, with the majority of work concentrated in New England and limited international engagement including one project in Oxfordshire, England.
The firm's underlying craft combines traditional hand drawings, CAD, and computer modeling, with particular specialization in historical window preservation research and energy efficiency studies. Its most notable technical contribution is a peer-reviewed white paper titled 'A Comparative Study of the Cumulative Energy Use of Historical Versus Contemporary Windows,' which has been adopted by the National Park Service and the National Trust for Historic Preservation as a reference for preservation decisions. The firm has also published a book, 'New Rooms for Old Houses,' under the imprimatur of the National Trust for Historic Preservation, and its founder has earned the FAIA designation held by fewer than 3% of AIA members.
FSA operates as a privately held, founder-owned professional services practice with project-based revenue derived from architectural fees. Engagement begins with a direct consultation with the principal, and business is generated almost entirely through referrals, word-of-mouth, and the firm's reputation within the historic preservation and classical architecture communities. Pricing is negotiated on a project-by-project basis and typically follows a milestone billing structure aligned with schematic design, construction documents, and construction administration phases. The firm's primary customers are affluent homeowners, historic property owners, and renovation/addition clients in New England seeking period-appropriate, preservation-minded residential architecture.
