Fort Point furthered its tech-heavy neighborhood reputation Monday, as Amazon confirmed it will lease 150K SF at 253 Summer St. for a new Boston office.

The building is adjacent to where General Electric is building its new global headquarters and should house Amazon employees by spring 2018, the Boston Business Journal reports. The e-commerce company hosted a ceremony Monday at its Kendall Square office to also announce it planned on hiring 900 more employees in the area. It already has over 1,000 employees between its Cambridge office and space at a Back Bay WeWork.

It was reported in May that Amazon was close to signing a deal for space in the Fort Point office building, which was originally home to the insurance division of Partners Health Care. It was previously shown to executives with General Electric and Reebok when they were looking for headquarters space in the neighborhood. Software company Red Hat recently opened a 40K SF office nearby on A Street.

Amazon said it plans to keep its other local offices while it expands into Fort Point.
