CORE has worked with Gould Property Company and Oxford Properties Group to design 600 Massachusetts Avenue NW.

600 Mass is located between Massachusetts Avenue, and Eye and 6th Streets NW in Washington, DC. The 11-story building offers over 400,000 SF of multi-tenant and retail space. Its design combines highly-efficient floor planning, clean aesthetics, and forward-thinking amenities. And the green spaces blur the line between indoors and outdoors. “We envisioned this building as a glass crystal embedded in a brick block – mediating between high-rise Massachusetts Avenue and historic Eye Street.” said Guy Martin. 600 Mass has a very complex geometry due to the site's condition. It starts as a 11-story glass office tower facing Massachusetts Avenue. Then the building shape cascades down towards I Street in a series of landscaped terraces. Finally, it ends in a brick façade reinforcing the adjacent historic structures. In addition, the landscape terraces not only provide outdoor space for the adjacent office spaces, but also contribute to the building’s LEED Platinum rating. Moreover, 600 Mass offers many high-end amenities, including a spa-quality fitness center, bicycle locker room, multi-use conference facilities, and a rooftop living room. “There are no other office buildings in Washington DC with the amount and quality of green space that 600 Mass has,” said Ron Ngiam. “When Spring growth begins, the outdoor areas at 600 Mass, and especially the rooftop terrace, are spectacular.” The design was subject to review by the Historic Preservation Review Board, the District of Columbia’s Office of Planning, and the Chinatown Review Board. The City Council also had approved an alley closing. 600 Mass opened in December 2016. Tenants now include Venable, Haworth, Brunswick, Oxford Properties Group, and Farmers and Distillers.
