The Best Mixed-use Contractors in San Francisco

September 17, 2018 14 Min Read

Access to a large talent pool, the possibility of venture capital, and proximity to like-minded individuals makes San Francisco an attractive location for tech-startups. In addition to big-league players such as Google, Facebook, and Apple, there are more than 2,000 startups in San Francisco setting up shop.

Naturally, San Francisco hosts some of the world’s most beautiful workplaces. Google’s Googleplex resembles a playful, inventive campus, while Apple’s future workplace is dubbed ‘The Spaceship’. Another well-known tech giant, Twitter, opted to reinvent an older building, turning a former retail store into a modern “bird’s nest”.

While architects get the credit for these designs, it is the contractors who bring to life their visions from blueprint to structure. Below are the best office contractors in San Francisco, none of whom have any shortage of experience in creating complex, modern workplaces.
