Google’s appetite for office space across the Seattle region has intensified in recent years, and it is on the verge of a major milestone.

The search giant is approaching a threshold of 2 million square feet of office space spread across several cities in the area. That’s as much space as in the 76-story Columbia Center, the city’s tallest skyscraper, plus another mid-rise office building. Using standard leasing ratios of 150 to 200 square feet per employee, Google’s footprint could eventually house as many as 10,000 workers. By comparison, the company had about 3,400 employees in the region as of March.

Google is one of more than 100 companies from around the globe that have set up engineering centers in the Seattle region. In many ways, Google started the trend. The search giant first opened its doors in the Seattle area 14 years ago, and since then, Google has built up one of the largest engineering outposts in the area.

In the Seattle area, Google’s scale as an out-of-town tech giant is rivaled only by Facebook, which topped 3,000 employees in the region as of November and has also been adding space rapidly.

These engineering outposts are competing with local companies for a deep roster of tech workers, thought to be more loyal than their counterparts in the San Francisco area. Seattle’s tech talent pool is now the best in North America, according to CBRE’s annual Scoring Tech Talent report, and Google is looking to take advantage.

Here’s a breakdown of Google’s growing Seattle-area footprint:

  • In Seattle, the Google Cloud campus in Amazon’s backyard of South Lake Union in Seattle — which totals 930,000 square feet of office space across three buildings — is inching closer to opening. Even after it moves into the new campus, Google plans to hold on to several buildings it amassed in the nearby Fremont neighborhood over the years.
  • A recent report from Broderick Group estimated that Google will soon hit 1 million square feet of office space in Kirkland, Wash. The tech giant has long been rumored to either lease or buy a big chunk of space in the Kirkland Urban project that features about 400,000 square feet of office space as part of the first phase, with more to come. This week, the Puget Sound Business Journal reported that Google is building out a new floor of office space in a nearby building.
  • Earlier this year, Google reportedly leased 80,000 square feet in Bellevuewhere Amazon is growing rapidly — at a building called One Twelfth @ Twelfth, with plans to lease another 30,000 square feet.

We’ve reached out to Google for further comment and we will update this post if we hear back.

And here’s how Google’s presence compares to some of the other major tech giants in Seattle, both homegrown and from out-of-town.

The growth of Google, Amazon, Facebook and other huge companies in the Seattle area has put significant pressure on the local real estate market. The vacancy rate, the amount of available office space, is down to 8.8 percent in Seattle and 9.6 percent across the region is a whole, according to a recent report from real estate firm JLL.

In Seattle alone there are 13 companies looking for at least 50,000 square feet of space, per JLL. Downtown Seattle is down to only three chunks of space larger than 100,000 square feet, with a few more on the way thanks to an active construction pipeline.
