The San Mateo County Navigation Center (SMCNC)—supportive interim housing for formerly unhoused people “navigating” their way to permanent quarters—was built for speed. The Office of Charles F. Bloszies coordinated the facility’s design-build delivery and developed its prefabricated modular construction system, as well as oversaw a team of government, community service, and design professionals, to complete the 2.5-acre, 53,800-square-foot, 240-unit center in California’s Silicon Valley in less than a year.
