This classical revival building was built in 1909 in San Francisco Nob Hill area. Many alterations have transpired but the architectural harmony is still consistent as a whole. The new glass pavilion will integrate the classical legacy with 21st century architecture. Situated within the existing courtyard, the glass pavilion will accommodate a complex program of events and offer a unique experience to its occupants. The design simplicity represented a technical and economic solution to overcome problems of bridging long span, heating, ventilation, light and shade. The Secretary of the Interior’s Standards for Rehabilitation were used as a reference guide for historic structure. Transfer Development Right, “TDR” was re-calculated to make room for this project.
