Make room, Jeanne Gang: The Transbay Transit Center development is bringing another top name to San Francisco.

Rem Koolhaas, Hon. FAIA, will design a 550-foot residential tower on Folsom Street between First and Fremont Streets, The San Francisco Chronicle reports. The developer, Related, won the bid from the city's Office of Community Investment and Infrastructure to develop one of the 11 properties that San Francisco is selling in order to finance the Transbay Transit Center at First and Mission Streets.

Studio Gang confirmed to ARCHITECT last month that Gang, FAIA, et al. are working on a tower on Folsom Street—three blocks from the site where Koolhaas's Office for Metropolitan Architecture (OMA) will build a tower.

The OMA-designed tower will feature a mix of rental and condominium apartments; at least 27 percent of the units must be set aside for affordable housing.

OMA previously designed a Prada store for Union Square, but the development was spiked in 2001.
