What Klopf Architecture does
Klopf Architecture is a privately held, San Francisco-based residential architecture firm founded in 2001 by John Klopf. The firm specializes in modernist residential design with a particular emphasis on mid-century modern (MCM) architecture and the restoration, modernization, and adaptive reuse of Joseph Eichler homes. Its portfolio of 175+ completed projects spans remodels, additions, and ground-up new residences across California, including Sacramento, San Jose, San Mateo, Palo Alto, Sea Ranch, Sonoma, and, more recently, Malibu. Technical differentiation centers on certified Passive House design expertise held by the founder, net-zero energy home design, and fire-resilient construction techniques demonstrated on the post-Woolsey Fire Malibu Glass Box House.
The firm operates a professional services model, generating revenue through project-based architectural fees for design, documentation, and construction observation. Services are organized around five core offerings: full residential architecture, mid-century modern remodels, Eichler home restoration, new residence design, and — as of 2024 — an in-house interior design department headed by a dedicated Director. The team of approximately 20+ includes three principals (John Klopf, Geoff Campen, and Angela Todorova), an Associate Architect, a Director of Interior Design, multiple lead/senior designers and designers, and program management and accounting support.
Go-to-market is sales-led and content-driven: the firm relies on earned media in outlets such as Dezeen, Dwell, ArchDaily, Contemporist, One Kind Design, and Houzz (where it has won Best of Houzz for 15 consecutive years, 2012–2026), supplemented by participation in home tours such as the Silicon Valley Modern Home Tour and direct client consultations. All services are delivered directly to homeowners, with no resellers or platform intermediaries.
