Construction on the first set of 8,000 homes slated for San Francisco’s Treasure Island and neighboring Yerba Buena Island has begun.

Connected by causeway to the larger Treasure Island, Yerba Buena Island will soon hold a community of 266 luxury residences, with the first 124 in a condominium building called The Bristol and scheduled to open in April or May 2021.

The rest, Wilson Meany partner Chris Meany said, will be a mix of flats and townhomes his team expects to complete at around the same time. Development partners Wilson Meany and Stockbridge Capital gathered Tuesday afternoon to celebrate the condominium project starting vertical construction.

“The other buildings take less time, so we’ll be starting a big chunk of the rest of the buildings at the end of this year,” Meany told Bisnow.
