Amazon has scooped up the Bellevue, Wash., Expedia headquarters building that the travel giant will soon vacate as it prepares to move into its new waterfront headquarters in Seattle.

Equity Commonwealth, the owner of the building, disclosed in a filing with the U.S. Securities and Exchange Commission that Amazon has signed a 16-year lease for more than 400,000 square feet in the tower. The deal takes effect in 2020 and includes all the office space in the building.

Amazon issued the following statement, confirming the lease Tuesday: “We currently have 2,000 employees in Bellevue and are leasing new space to add capacity for an additional 2,500 Amazonians by 2020.”

The Puget Sound Business Journal first spotted the filing.

Amazon has been eyeing the Expedia tower for a while now, and the move comes approximately a year after the tech giant moved into its first Bellevue office building. Today, Amazon has approximately 130 open positions in Bellevue.

The two Bellevue buildings give Amazon a footprint in the city of more than 750,000 square feet. Amazon has been linked to other available spaces in Bellevue that could push its presence above 1 million square feet there.

According to GeekWire research, the latest lease pushes Amazon close to a footprint of 14 million square feet of office space in the Seattle area, encompassing owned and leased property as well as future commitments. That does not include the company’s distribution centers and Whole Foods stores in the area.

Amazon is one of a growing list of tech giants to have offices in Seattle and a city on the east side of Lake Washington. Other examples include Google, Facebook, Tableau Software and soon Expedia, which will keep some of its Bellevue space after moving the bulk of its HQ workforce to Bellevue.
