Aggregate is located at 900 Second Street NE, just behind Union Station at the crossroads of the Capitol Hill, NOMA and H Street neighborhoods.

Our offices are housed in the historic Railway Express Building, designed in 1904 by Daniel Burnham, the architect for Washington's Union Station and New York's famous Flatiron building.

Today, we enjoy working in a building with such rich history and in a neighborhood with a view towards the future. We strive for our work to reflect this appreciation for both tradition and innovation.
