140 New Montgomery Historic Renovation

San Francisco’s historic Pacific Telephone and Telegraph building office building, built in 1925, is a 26-story steel frame Art deco high-rise designed by Timothy Pflueger.

It was restored into the ideal office space, blending timeless design and expansive Bay and city views with 21st-century interior building systems. Tenants have a high degree of flexibility and options: Class A, fully air-conditioned space, or ultra-low and passive energy office space. The primary objective was to attract various tenants and offer flexibility and simplicity at a low cost, thereby making a truly green office affordable to all prospective tenants.

Introba (formerly Integral Group) provided mechanical and plumbing engineering and preliminary energy and occupant comfort modeling, which integrated façade performance analysis for the $60-million renovation. The renovation required the complete replacement of all major systems of the building as well as seismic upgrades, repurposing of the utility and services, and a new landscaped courtyard at the rear of the building. High-end retail and restaurant spaces occupy the historically preserved ground floor.
