(AP) — The federal government will move 900 employees to downtown Kansas City.

The General Services Administration announced Monday that its employees will move from the Bannister Federal Complex in south Kansas City to an office building near Union Station.

The Kansas City Star reports (http://bit.ly/1bRZkoA ) the move to Two Pershing Square will include a 20-year lease valued at nearly $50 million, with the government receiving an $8.6 million discount.

GSA official Kory Hochler says the agency has the right after seven years to reduce the amount of space it occupies or completely leave the building.

The agency is expected to take occupancy in December 2014, and the relocation is expected to take three to five months.
