The Heritage Foundation, House Annex Project

Washington, DC

The Heritage Foundation is a Washington, DC-based think tank focused on creating and promoting conservative public policies. In early 2008, after nearly doubling the size of their Massachusetts Avenue headquarters facility, Heritage found themselves in need of a new type of space that was more user-friendly and accessible to their target audience – the congressmen and women on Capitol Hill. They purchased 227 Pennsylvania Avenue SE, a historic structure in the Capitol Hill neighborhood that had become available after a recent fire, and set out to transform it into a state-of-the-art conference space to serve the needs of members of Congress and their staffs.

We joined the Heritage team as project managers to assist in the design and construction of the highly complex historic renovation and rehabilitation project. In order to achieve project goals to double the square footage of the building and visually align with adjacent structures, the building required excavation of a full basement beneath the existing two-story structure, addition of a new third story, and restoration of the existing facade. Getting it right meant assembling an especially knowledgeable and creative team, and we spearheaded the selection of all design and specialty consultants. Because of the historic nature of the project, one of the most significant challenges was expediting the lengthy permitting and historic review and approvals process. To minimize schedule delays, we proposed and led a phased permitting process so work on site could continue uninterrupted. The award-winning project was completed on time and approximately 9% under the initial project budget – granting Heritage the access and facilities they need to further their policy position.
