WASHINGTON – Transwestern Real Estate Services (TRS) announces DRB Group has signed a 56,409-square-foot lease to relocate its corporate headquarters to The Summit at Washingtonian, a Class A, LEED Certified, 193,199-square-foot office property at 9711 Washingtonian Boulevard in Gaithersburg, Maryland. Transwestern’s Keith Foery, Phil McCarthy, and Guy Copperthite represented the property owner, Principal Asset Management®, in lease negotiations. DRB Group was represented by Dan Falls of CBRE.
DRB Group, a national homebuilder operating in 14 states, plans to relocate from 2099 Gaither Road in Rockville, Maryland, in the third quarter of 2026. The company will house its corporate headquarters on the top two floors at The Summit and its title company and design studio on the first floor. In addition to meeting DRB Group’s space requirements and offering employees an improved workplace experience, the move will enhance brand recognition through prominent exterior signage on the top of the eight-story building facing I-270 and Fields Road.
“This new headquarters represents an exciting step forward for DRB as we continue to grow as a top 20 national homebuilder,” said Ronny Salameh, President and CEO of DRB Homes. “With more than 1,600 employees operating in 14 states across 19 divisions, this expanded corporate office will house over 200 of our team members, bringing together DC Metro regional staff, DRB Development, Keystone Title, and the award-winning DRB Design Studio showroom under one roof. The new office will serve as an innovative hub to support our employees and customers as we build communities nationwide in partnership with Sumitomo Forestry America.”
The Summit offers easy access via ICC, I-270, and Shady Grove Road, and is just minutes from over 1.75 MSF of retail amenities, restaurants, and hotels. The property features a spacious two-story atrium lobby, floor-to-ceiling windows, and a full-service fitness center with lockers, showers, and an exercise room. Future building improvements include renovations to the main lobby, a new conference center, and a grab-and-go deli.
“We are excited to welcome DRB Group to The Summit at Washingtonian. Their decision to lease space with us for their corporate headquarters is a strong vote of confidence in our property and the community. We look forward to supporting their continued growth and success,” said Troy Koerselman, managing director of asset management and development at Principal Asset Management.
