What PhD Design does

Ph.D. Design Inc. is a Toronto-based, full-service architectural design firm founded in 1985 by principal designer Peter Marzynski. The company specializes in high-end residential architecture, including new construction, additions, renovations, restorations, and interior design, with secondary work in commercial façade and storefront design. It serves affluent property owners in prestigious Toronto neighborhoods (Rosedale, Forest Hill, The Kingsway, Etobicoke, Mississauga, King City), with recent project activity extending into Prince Edward County and the Caribbean (Port of Spain).

The firm's service stack covers the full project lifecycle: feasibility study, concept design, working drawings, structural concept in collaboration with in-house P.Eng engineers, building permit negotiations, interior design, project and construction management, site supervision, and budget design. Built on decades of accumulated design work and a multi-generational architectural heritage (Marzynski lineage from Warsaw), the practice blends traditional sensibilities with contemporary requirements and modern construction technologies. Distribution is entirely direct, with the principal personally managing client relationships throughout each engagement.

The business operates on project-based professional services fees, without public pricing, recurring revenue, or subscription component. The firm is privately held, with no outside institutional ownership, and is supported by a small multidisciplinary team that includes architects (OAA), interior designers, technologists, and structural and mechanical engineers. Marketing footprint is minimal — limited to a Houzz profile, an Instagram showcase, and the corporate website — relying primarily on referrals and the principal's reputation built across approximately 500 projects since founding.
