Historic Preservation
Historic preservation is the root of HSU's core business, and we take great pride in meticulously preserving historic structures for the benefit and enjoyment of future generations. We combine our expertise in protecting the integrity of historic structures with a focus on efficiency and cost-effectiveness.
We receive frequent recognition for our historic preservation efforts with awards from industry associations and agencies such as the Maryland Park & Planning Commission, Associated General Contractors of Washington, DC, CAREN Enterprise, and the Peerless Rockville Historical Society.
Our diverse portfolio includes the renovation of nationally recognized sites on the National Register of Historic Places, as well as, other historic properties.
