The Clifton Mansion was originally built in 1802 as a Georgian style stone mansion, by the Baltimore merchant Henry Thompson. Johns Hopkins later bought the mansion for a summer residence and added the mansion's signature tower and Italianate features in 1852.

C&H Restoration and Renovation has been involved in the restoration of both the main stairs and the tower stairs. In 2019, the restoration work moved to the dining room, where C&H has participated in the coordination of all aspects of the restoration of this room, from the structural work needed, to the in kind millwork replication and installation, to the restoration of the original mural work on all of the walls and ceilings of this stunning room.
