Rockville, MD 20852

Built in the late 1960s, 5600 Fishers Lane, the "Parklawn Building" has housed government agencies and employees for more than 40 years. Situated less than one half mile from the Twinbrook Metro station, 5600 Fishers Lane is one of the largest and most iconic buildings in Montgomery County, MD. The JBG Companies completed a four-year, tenant-in place renovation, which delivered in 2015 four brand new cores, all new glass curtain wall, a new main lobby and a stunning 14-story atrium. The building also received a new roof, an energy efficient DOAS HVAC system, another level of garage parking and several other major upgrades. 5600 Fishers Lane is truly embracing sustainability in its proximity to mass transit, re-use of an existing building and goal of achieving a LEED Platinum certification and Energy Star rating.  With this new expansion, 5600 Fishers Lane can now provide office space to more than 4,000 federal employees and anchor a growing community of health and research-related agencies in the Twinbrook Metro area.

Features: Twinbrook Metro Park is a mixed-use project containing two office buildings and five laboratory facilities, located steps from the Twinbrook Metro Station on Metro’s red line in Rockville, Maryland and adjacent to the new Twinbrook Station mixed-use development.
