Plans to build a “skybridge” connecting Twitter’s headquarters in Mid-Market with another, smaller building used by the social media giant received initial approval on Wednesday.
Twitter’s landlord, Shorenstein Properties, wants to build a concrete, metal, and glass connector between the ninth floor of the Furniture Mart building at 1355 Market St., and the ninth floor of 875 Stevenson St.
Twitter’s headquarters since 2012, the terra cotta Furniture Mart building, is protected by the strictest historic preservation standards.
The bridge is proposed for the rear of the building, above an alley that’s no longer in the public right of way, and away from the terra cotta façades.
This all helped convince The City’s Historic Preservation Commission to award it unanimous approval on Wednesday.
Before construction can begin, further approval is needed from The City’s Planning Commission, which is scheduled to weigh in on the skybridge early next month.
Shorenstein Properties purchased the building for $110 million in 2011, shortly before Twitter took occupancy in 2012 thanks to a controversial city tax break.
The company is trying to sell the building for as much as $800 million, according to the San Francisco Business Times. A spokesman for Shorenstein declined to comment on the sale and on the construction of the bridge.
A previous bridge between the two buildings was demolished in 2012, during renovations undergone at Twitter’s request before the company moved in.
