Foster + Partners and Heller Manus Architects are to design a 2 million sq ft mixed-use development in San Francisco for TMG Partners and Northwood Investors LLC. The First and Mission scheme will feature two high-rise towers, the greatest of which will be the tallest residential project on the West Coast.
An 850ft-high hotel, residential and office tower feature highly flexible ‘super-sized’ floor plates with an open layout supported by an orthogonal structural system devised for seismic stability. This tower will be coupled with a shorter 605ft-high structure dedicated to residential units.
Lord Foster, Founder and Chairman of Foster + Partners commented: “The First and Mission towers are incredibly exciting in urban and environmental terms - bringing together places to live and work with the city’s most important transport hub, the project further evolves a sustainable model of high density, mixed-use development that we have always promoted.
The point where the two towers meet the ground will be marked with an open and accessible ‘urban room’ as demonstrated in the single visual released by the architects. There are also plans to insert pedestrian routes through the site to ‘knit the new scheme with the urban grain of the city’.
San Francisco is rife with high rise towers and has been for many decades. Notable tall towers include the Transamerica Pyramid (1972), the Millennium Tower (2009) and Four Embarcadero Center (1982) while a number of proposed towers - such as the Transbay Transit Center and Tower, and the 50 First Street Tower - promise to reach above 900ft.
TMG Partners president and CEO Michael Covarrubias notes: “The collaboration of Foster + Partners and Heller Manus Architects puts San Francisco squarely in league with the world’s greatest cities, including London, Shanghai, Kuwait, Paris and New York. The Transbay site will be transformative and will be the last mixed-use development of this scale in this area of downtown.”
