Suyama Peterson Deguchi (SPD) is a Seattle-based architecture firm known for its refined Northwest contemporary design. Founded in 1971 by George Suyama, FAIA, and later joined by partners Ric Peterson, FAIA, and Jay Deguchi, the firm offers a comprehensive range of services spanning architecture, interiors, and custom furniture design. SPD’s work is guided by a philosophy of restraint and clarity—employing elemental forms and minimal means to craft spaces that evoke a quiet, emotional resonance.
The firm’s approach emphasizes editing and refinement, reducing visual noise to create environments with depth, nuance, and lasting presence. Whether designing private residences, galleries, or experimental retail spaces, SPD tailors each project to its site, program, and client—eschewing stylistic formulas in favor of a context-driven response. Located in Seattle’s South Park neighborhood, SPD’s studio also houses *3×10*, a showroom dedicated to furniture and accessories. Across all scales and typologies, the firm remains committed to creating architecture that is timeless, thoughtful, and deeply rooted in place.
