What McClellan Architects does

McClellan Architects (operating as McClellan | Tellone) is a Seattle-based architecture and interior design firm founded in 1997 by Regan McClellan and Christopher Tellone. The firm provides comprehensive design services to affluent residential clients across the U.S. West Coast, including architectural design, interior design, landscape design, lighting design, furnishing and art curation, and master planning. Its portfolio spans custom waterfront homes, steep-slope and rocky-outcropping residences, equestrian estates, and high-end remodels, with notable projects including Bay House (Bellingham Bay), Glasswing (Bellingham), Eyrie, River House (Columbia River), and Eastlight.

The firm's go-to-market is relationship-based and sales-led. Prospective clients engage through direct consultation, and acquisition is driven by the published portfolio, project testimonials, and a downloadable process document. Delivery runs from concept through construction administration, with the firm positioning itself as the client's advocate throughout the build. On individual projects, McClellan | Tellone pairs with regional general contractors — Dawson Construction and Emerald Builders are named — and selective design collaborators such as Lisa Staton Interior Design, rather than formal joint ventures.

Revenue is generated through professional service fees tied to project scope, complexity, and construction administration. The firm operates from a single Seattle headquarters (3309 Wallingford Ave N) and markets through its website portfolio, an active Instagram channel, and word-of-mouth within the Pacific Northwest luxury residential market. With 11–50 employees and no external funding, the firm is privately held and founder-owned; financial metrics are not publicly disclosed.
