After the original courthouse burned down in the 1920s, James J. Baldwin designed a new courthouse for Murphy, to be clad in local marble, which was completed in 1927. Recent updates designed by Clark Patterson Lee consist of renovations of the historic building and 24,000 thousand square feet of three-story additions. Existing exterior upgrades included re-pointing the locally quarried marble, replacing terra cotta, adding accessible ramps, and complete window replacement. Interior systems were completely upgraded, elevators added, along with expanding court/county operations. The plan was to respect and not overwhelm the historically significant courthouse.
