The preliminary designs for two towers designed by Foster + Partners and Heller Manus Architects which could rise up to 910 feet in height at the corner of First and Mission have been submitted to Planning for Environmental Review.
As we first reported last year, TMG Partners’ proposed 50 First Street development includes over 1 million square feet of office space along with hundreds of condos. A possible hotel component has since been added as well.
While the original plans called for the condos to fill the shorter 605-foot tower fronting Mission Street, the latest plans call for spreading the residential units between the two buildings and topping the 910-foot tower fronting First Street which would rise 850-feet to the roof with a 60-foot crown, a move which would make them the highest residential units in San Francisco (a title to which the 802-foot tower rising at 181 Fremont has been laying claim).
Regardless, the 910-foot tower would become the second tallest building in San Francisco, behind the Salesforce Tower which will rise to a height of 1,070 feet and overtaking the Transamerica Pyramid, the current tallest building in San Francisco which reaches a height of 853 feet.
TMG is hoping to start construction by the end of 2015 and complete the project as early as 2018. The existing 88 First Street building on the corner between the two proposed towers will be renovated rather than razed for a third tower as was previously proposed.
