In 2006, our team undertook the historic plaster restoration of the Old DC Courthouse at 451 Indiana Avenue NW, a landmark originally constructed between 1820 and 1849. This building, the fourth oldest public structure in Washington, D.C., had served various roles over the years, including as City Hall and later as a courthouse, and had been vacant since 1999.
As part of a comprehensive $99 million renovation led by Hensel Phelps Construction Company, our focus was on restoring the courthouse's original plasterwork. This included repairing and replicating intricate plaster moldings, cornices, and ceiling medallions that had deteriorated over time. We employed traditional materials and techniques to ensure historical accuracy, aligning with the standards set by the National Register of Historic Places and the Save America's Treasures program.
The restoration also involved addressing structural challenges, such as stabilizing compromised plaster surfaces and integrating modern systems without compromising the building's historical integrity. Our meticulous work contributed to the successful transformation of the Old DC Courthouse into the new home of the District of Columbia Court of Appeals, which reopened in November 2008.
This project stands as a testament to our commitment to preserving the architectural heritage of Washington, D.C., ensuring that historic structures like the Old DC Courthouse continue to serve the community while honoring their storied past.
