Wells Real Estate Funds, owner of the 275,400-sf structure at 80 M St., decided to hand over both leasing and management responsibilities to Jones, after having relied on Spaulding & Slye Colliers and Cottonwood Management, respectively. And 1800 K St. owner Paramount Group Inc., which will continue to handle its own management duties, is now relying on JLL to oversee leasing at its 205,000-sf building, leaving behind former leasing agent Transwestern.

Navy Yard Metro Center, as 80 M St. is known, sits in the Capitol Hill area of the city and is home to the likes of BAE Systems, BearingPoint, CACI and Northrop Grumman. Developed in 2001, the seven-story property sits across from a Metro station and features an on-site fitness center. Space in the brick, metal and glass building is being marketed for $44 to $46 per sf.
