Located just south of San Francisco’s Financial District and blocks away from the bay, MIRA Tower is a housing development that grabs your attention with a highly detailed geometric form. The project joins a spate of recently completed and under construction towers in the Transbay Development Zone, including Pelli Clarke Pelli Architects’ Salesforce Tower and the Heller Manus Architects’ 181 Fremont. Designed by Studio Gang Architects in collaboration with facade consultant Heintges and fabricator Permasteelisa, the tower presents a spiraling aluminum-and-glass facade arranged in a panoply of bay windows and terraces.
Developed by Tishman Speyer, the size of the project is formidable and consists of both a tower and a terrace of townhouses—with a footprint of 50,000 square feet and spanning 700,000 gross square feet. To comply with FAR constraints and rules set out by the district zoning guidelines, the initial design reached a height of 300 feet. Following a request to the city government, the allowable height of the tower was raised to 400 feet with the inclusion of 156 below-market-rate apartments, or just under half the total number of units.
