Residential – Custom

MASON Architects is a San Francisco Bay Area boutique architecture firm founded by Peter T. Mason. AIA LEED, BD+C, a 35-year veteran of the luxury hospitality industry.

Peter is a longtime resident of the Town of Woodside, CA, a former Mayor and member of the Woodside Town Council. He served for several years as the chair of Woodside’s Architectural & Site Review Board, and on the Portola Valley / Woodside Fire Wise Committee. His qualifications include LEED certification. The Firm’s custom residential business focuses on the towns of Woodside, Portola Valley and their neighboring communities. It is no secret that creating a home in these exclusive rural communities can result in a challenging design approval process owing to strict design guidelines, a high number of nonconforming lots, and other site constraints. The Firm is accomplished at successfully shepherding projects through this process.
