Chadbourne and Doss Associates

What Chadbourne and Doss Associates does

chadbourne + doss architects pllc is a privately held, husband-and-wife-owned residential architecture firm operating from two studios in Seattle, Washington and Astoria, Oregon. Founded approximately 1994-1995 by principals Lisa Chadbourne and Daren Doss, the firm has practiced for 30 years focused on custom single-family residential architecture, major renovations, historic preservations, mid-century modern restorations, accessory dwelling units, and selective commercial/hospitality projects across the Pacific Northwest and West Coast.

The firm's core offering is full-service architectural design spanning pre-design evaluation, schematic design, design development, construction documents, and construction administration, supported by an in-house interior design capability and collaboration with external landscape architects, structural engineers, builders, and craftspeople. Notable proprietary elements include the HOMEwork Assignment, a structured client-discovery questionnaire used to uncover lifestyle and personality inputs beyond programmatic needs, and a site-responsive design methodology emphasizing challenging sites such as steep slopes, tricky zoning, and waterfront contexts. The documented portfolio of more than 20 projects includes award-winning residences such as Prow House (18.5 kW solar, net-zero capable), Viewpoint Residence (5,725 sq ft), The Perch (5,500 sq ft aging-in-place home), Past Present House (4,800 sq ft historic French Norman renovation), Cycle House (2,500 sq ft net-zero), and the 17,000 sq ft Red Building adaptive reuse in Astoria.

The business model is professional services fee-for-engagement on a quote basis with a complimentary first pre-design hour. The go-to-market motion is direct-to-consumer via website contact form, brochure distribution, and principal-led in-person consultations at both studios; there is no formal sales force and principals handle all client relationships. Marketing relies on website portfolio, Instagram, LinkedIn, Pinterest, Facebook, an editorial blog/journal, and earned media features in Dwell, Sunset Magazine, Wall Street Journal, New York Times, Archello, and others. The firm is independently owned by its two founders with no external investors, no subsidiaries, no funding rounds, and no disclosed revenue. Recognition includes Forbes Top 200 Residential Architects (2025), Forbes Best-In-State Residential Architects (2025), Sunset Home & Design Award for Best Waterfront Modern (2026), Architizer 30 Best Architecture and Design Firms in Seattle (2025), and an Archello House of the Year finalist nomination for Prow House (2024).
