Foster Tower To Dominate San Francisco

The Transamerica Pyramid, one of the most iconic skyscrapers in the world, has dominated the view of San Francisco for decades. All that could soon be about to change if proposals led by Foster+Partners for 50 First Street get the go ahead and rival it on the skyline.

Perhaps drawing most generously from their famous Hearst Building in New York with diagonal crossbracing and the appearance of chamfered corners. Unlike the Hearst Building however, the plans here are for a skyscraper that tapers in as it rises radically reducing the bulk of the tower on the city skyline, thus corresponding with the necessary sunlight requirements for the site by locating the majority of the 125,000 square metres of office space in the bottom part.

The project features an expressed structure of steel crossbracing that sits atop 20 metre tall stilts creating a public space under it that pedestrians can pass through, much like that of the Leadenhall Building in London. Again like the Leadenhall Building the service core is situated to the rear of the development that allows open an unobstructed floors whilst the rear of the building will present a sheer face. The aim here though is structural efficiency.

Rising to a height of 277 metres it will be eleven metres taller than the Transamerica Pyramid, spire excluded, if built, although plans for a taller nearby tower for Salesforce may trump it.
