Green-Roofed Twitter Headquarters in San Francisco Also Has a Yoga Studio!

We've seen the inside of several funky corporate offices, including <a href="http://inhabitat.com/google-employees-in-zurich-zooglers-have-the-worlds-coolest-re-purposed-office/">Google</a> and Facebook, but Twitter might have outdone them all with their new green-roofed headquarters in San Francisco. Part of the city's plan to revitalize a seedy neighborhood, Twitter was given a tax reprieve for moving into the 11-story art deco office building on 10th and Market street renovated by <a href="http://www.interiorarchitects.com">Interior Architects</a> and <a href="http://www.lundbergdesign.com">Olle Lundberg Design</a>. (RMW Architects is the base building architect.) But the new headquarters for 800 employees also reflects something of a <a href="http://inhabitat.com/interview-yves-behar-on-sustainability/">sustainability ethos</a>. Hit the jump for the deets and flip through the gallery for a closer look.

Twitter has opened their new headquarters in San Francisco

Housed in an 11-story art deco building on Market and 10th, the move is part of an agreement with the city

In exchange for a tax reprieve, Twitter's presence in a seedy neighborhood is expected to create some kind of urban revival

But Twitter also reveals something of a sustainability ethos

This is a micro health kitchen stocked with all kinds of holistic goodness

The "Birdfeeder" - get it?

Employees have loads of gathering spaces to choose from

You guessed it: this is the yoga studio. Dream office? We think so.

The 9th floor reception desk looks suspiciously like it is made of recycled materials.

The rooftop garden is already looking pretty good

This is another gathering space just outside the groovy health kitchen
