The new, 25,000-square-foot Thurmont Regional Library in Frederick County, Maryland, takes its design inspiration from the rural community's agricultural heritage and the area's historic Catoctin Furnace. Local materials, such as stone and wood, are used throughout. Where possible, the team selected sustainable alternatives such as hardy board, metal roofing, and other materials which do not require maintenance. Heavy timber roof trusses add warmth and drama to the interior.
