General Electric has pushed back the opening of its new 12-story building in Fort Point to mid-2021 from 2019.

Instead, the company, which is relocating its corporate headquarters to the hip Boston neighborhood from Fairfield, Connecticut, will focus on revamping two decades-old buildings that used to house the Necco candy concern.

That essentially splits the ballyhooed HQ into two phases. The Necco work is already underway, and those buildings are expected to be ready for GE employees by mid-2019, per the Globe’s Jon Chesto.

Work on all three buildings had at one point been expected to wrap before 2019.

When all is said and done, GE’s new Fort Point headquarters is supposed to run to nearly 400,000 square feet of interior space and include what the company has dubbed “maker space” for employees, tech startups, students (both university and high school), and locals; a community work lounge; space for conclaves and presentations, never mind ample laboratories; and an employee cafeteria.

There will also be a pretty snazzy pedestrian bridge. But no helipad.
