After over two years in San Francisco’s SoMA neighborhood on Folsom Street, Twitter is moving their headquarters over to Mid-Market, at 1355 Market street, right across from the city’s skid row. No word yet on when the new offices will be open, but we suspect it will be sometime this week.

The move has been coming for awhile, but the building was under construction. In December, Twitter held a press meeting in their soon to be headquarters, and Business Insider captured some candid photos of the site. You can check it out by following these links to their page on Twitter’s future headquarters.

You might also recall that Twitter just underwent a huge restructuring coupled with a sizable increase in new hires. At the root of the changes seems to be an initiative to increase global reach and international advertising efforts. In fact, Twitter is still actively recruiting for multiple positions in London, Tokyo, and Dublin.

Since Twitter amped up its advertising strategy earlier this year, and added Promoted Tweets to its news stream, things have really taken off and they reached their 140 million active users milestone early last month.

While Facebook may be struggling in light of their recent public offering fiasco, Twitter is taking off like a rocket ship. But, it doesn’t sound like Twitter will be going public anytime soon. In fact, some even speculated Google might have a significant interest in acquiring them. We’ll see what happens.
