Seismic Retrofit & Historic Building Renovation
San Francisco, CA

Originally built in 1908 as the Home Telephone Company Headquarters, this steel frame structure with sandstone cladding underwent a major seismic retrofit as the building changed ownership and function. Huntsman Architectural Group was hired to renovate this high-rise building designed by Coxhead and Coxhead and noted as a San Francisco Historic Landmark, and convert the switching and call center spaces into a modern mixed-use retail and office building. The project involved close coordination with structural, mechanical, electrical systems; accessibility and code upgrades; and extensive Building and Planning Department interface.
