Microsoft is planning to revamp its headquarter campus in Redmond, Seattle, to improve collaboration and attract young engineers.

Citing unnamed people familiar with the matter, Bloomberg reported that the company has appointed architecture firm Skidmore, Owings & Merrill to work on the potential project, which is expected to cost billions of dollars.

The company said in a statement, "We continually work on Microsoft campus plans to anticipate future needs."

Microsoft is moving people from private offices to the 500-acre Redmond campus, which has 10 million square feet of space in about 80 buildings.

The company owns the majority of the campus. It has already renovated some of its facilities to add open work space.

The latest revamp is expected to include construction of new buildings and redevelopment of existing
facilities.

It could add amenities like restaurants, retail spaces and public artwork, apartments, and houses for visiting employees and interns.

A development agreement with the city of Redmond allows Microsoft to expand an additional 1.4 million square feet.

The company owns or leases 14.7 million square feet in the Puget Sound area.
