San Francisco, California
The Monadnock Building opened its doors for business in 1907, having withstood the great San Francisco earthquake and fire of 1906 while under construction. The Monadnock Building is one of the first steel frame, concrete encased buildings erected in San Francisco. The Monadnock Building, which over time was home to the executive offices of the nation’s largest railroads, a Prohibition-era speakeasy and a legendary jazz club, flourished for decades until falling into disrepair in the latter half of the century. In 1977, the then-owner, unwilling to renovate the building, was persuaded by the architectural firm of Whisler-Patri to sell the building rather than tear it down. The Monadnock Building was sold to a private investor who subsequently sold it to the AT&T pension fund in 1986. The Monadnock Building was then completely renovated, modernized and restored to its original grandeur by the architectural firm of Whisler-Patri and Charles Pfister. The Monadnock Building is now considered an historical landmark building. It is centrally located in downtown San Francisco, with close proximity to the North Financial District, Union Square and the Moscone Convention Center. As one of the premier Class B buildings in San Francisco, The Monadnock Building has excellent accessibility to all forms of public transportation, including BART, MUNI, and the historic Street Cars that run from Fisherman’s Wharf to the Castro.
