The Davis Companies (TDC) has leased 20,360 square feet with Datawatch Corp. at The Xchange on Crosby Drive in Bedford, where it will relocate its headquarters from Chelmsford this fall.

TDC, which acquired the eight-building, 475,000-square-foot campus in 2012, has also acquired four acres of land from the Massachusetts Department of Transportation for an additional 250 parking spaces. The new lot will increase the parking ratio to 3.2 per 1,000 square feet.

TDC is repositioning the former Bedford Business Park with new amenities including a fitness center with showers and locker rooms, café, patio and landscaping.

“We are thrilled to join this cohesive campus with activated space that provides amenities for the great employees that keep our business running and successful,” Michael Morrison, president and CEO of Datawatch, said in a statement.

CBRE’s suburban leasing team, led by Andrew J. Majewski, Jason Levendusky and Kerry Olson Hawkins, represented Datawatch in the transaction. Mark Cote from T3 Advisors represented Datawatch Corp. The transaction brings the occupancy rate up to 92 percent.
