1. 250 Massachusetts

The roughly 600,000-square-foot 250 Massachusetts Ave. is the second building to reach completion in Property Group Partners’ 2.2 million-square-foot revitalization project spread across three city blocks. All Capitol Crossing’s five buildings are designed to obtain LEED Platinum certification, with the 12-story 250 Massachusetts Ave. receiving the accreditation at the end of August. The property breaks into two towers on the fifth floor, with a tree-lined terrace separating the structures that also feature multistory lobbies and curtainwall glass.

Property Group Partners tapped Skidmore, Owings & Merrill as the master planner and Roche Dinkeloo as the architect. Located at the intersection of Capitol Hill and East End, the development will include district-wide energy cogeneration, a centralized water collection and reuse system that will treat more than 90 percent of stormwater runoff. Additionally, the project will feature eco-chimneys that employ biofilters to clean car fumes from the nearby Interstate 396 and an underground parking structure, returning clean air to the environment.

Located at 150 M St. NE, the more than 500,000-square-foot building is part of the 2.7 million-square-foot Constitution Square development that spans a full city block next to the NoMa-Gallaudet U Metro station. Along with the adjacent 349,000-square-foot Three Constitution Square, the pair was sold to a partnership between MetLife Real Estate Investment and Norges Bank Real Estate Management for $421.8 million in 2016. The 12-story Four Constitution Square reached completion in 2019.

The U.S. Department of Justice occupies both buildings, as well as Two Constitution Square. DOJ employees can travel between Three and Four Constitution Square buildings thanks to a connecting walkway. The Constitution Square buildings include street-level retail space, underground parking, automatic lighting controls and HVAC systems. Four Constitution Square became LEED Platinum certified in March 2020; the asset is the only one on the list to be awarded the certification in the first half of 2020.
