What MASON Architects does

MASON Architects is a privately held, founder-led boutique architecture firm headquartered in San Carlos, California, specializing in luxury hospitality, high-end custom residential, master planning, and historic preservation. Founded by principal Peter T. Mason, AIA, LEED BD+C, in 2013, the firm operates with 11–50 employees and delivers five core service lines: Custom Residential Design, Custom ADUs, Hotel + Resorts + Branded Residential, Master Planning, and Renovation + Historic Preservation. Its portfolio spans 150+ hospitality projects worldwide and several billion dollars in construction managed under Mason's personal direction, including flagship assignments for brand operators such as Marriott/W Hotels, Four Seasons, Ritz-Carlton, Montage, and St Regis.

The firm generates revenue through project-based professional services fees covering architecture, master planning, design, and construction administration, with pricing tailored to scope and not publicly disclosed. Go-to-market is principal-led and sales-driven: Peter Mason personally engages enterprise hospitality developers and high-net-worth residential clients, supplemented by referral networks among international brand operators and a digital presence on LinkedIn and Houzz. The current custom residential design portfolio exceeds $100 million in construction value, and active international engagements include the OMRAN-led multi-billion dollar beachfront development in Oman, the Ritz-Carlton Resort masterplan in Paradise Valley, Arizona, and the Four Seasons Tunis.

MASON Architects differentiates on three axes: deep principal expertise and civic involvement (15 years on the Woodside Town Council, including as Mayor, providing regulatory navigation in stringent design-review jurisdictions); award-winning portfolio credentials (e.g., W Muscat, World's Leading New Hotel 2019); and a consultant ecosystem (COWI, Burton Landscape, P49Deesign, Rockwell, and others) that allows a small core team to deliver complex international hospitality projects. Geographic reach spans the U.S. (CA, AZ, CO, WA, ME) and international markets including Oman, Tunisia, China, India, Egypt, Mexico, and Puerto Rico.
