The Douglass, the 740,000-sf anchor building of the transformative Bridge District development in Washington, D.C.’s Ward 8, is currently the largest multifamily housing project to pursue Zero Carbon Certification from the International Living Future Institute (ILFI).

The 757-unit building, which started construction in the summer of 2022, will be the first of a series of multifamily and office buildings to be built in the mixed-use development over the next several years.

All power for the building will come from renewable sources, including a 200 kW rooftop solar array capable of producing 200 MWh/yr.

Over 5% of parking spaces will be equipped with EV charging. Another 15% of parking spaces will be “EV ready” for future charging.

The building’s all-electric mechanical system will provide enhanced heating and cooling efficiency via a buildingwide condenser loop, which will transfer energy between residential, retail, and other uses.

“The Douglass represents our region’s largest ground-up development designed to be carbon net zero from operations," said William Passmore, Managing Partner of Redbrick LMD, the developer. "We are pushing the envelope on sustainability with a design that exceeds ILFI and LEED Platinum standards. Sustainable development that promotes human health and well-being and mitigates the impact of climate change is foundational to everything we do."


The excavation for the foundation of The Douglass is in its final stages, and the concrete pour is under way. Most of the concrete will be produced by an on-site batch plant. An optimized mix could reduce carbon emissions by 30% compared with traditional mixes. On-site production will reduce or eliminate carbon emissions attributed to transporting concrete to the job site.

Approximately 78 units are designated affordable, defined as at or below 50–60% of median family income in the District of Columbia (currently $129,000 for a family of four), depending on the unit. 

The Douglass, designed by ZGF Architects, will offer sweeping views of the Washington, D.C., skyline and Anacostia River. Its proximity to Anacostia Park will provide residents access to greenspace. Ground-floor retail will provide access to shopping, services, and amenities.


The Bridge District encompasses approximately eight acres of entitled matter-of-right, mixed-use density in support of nearly 2.5 million square feet planned to be developed into a neighborhood of multifamily apartments, retail, and offices.

Located in the path of growth along the Washington Metro’s Green Line, the Bridge District intends to provide premier work-from-home capabilities, attractive amenities and services for residents and visitors, a health and wellness theme, and access to nature in an urban environment.

All buildings planned for construction at the Bridge District currently target net zero carbon from operations and the highest levels of sustainability that are practically achievable for near-term multifamily development in Washington, D.C.
