Exterior restoration took place in 1983-86 with funding from the Maryland Historical Trust. Work included restoration or construction of windows and doors, and construction of the east porch to temporarily replace a long-missing enclosed stairwell or vestibule connecting the Brick House with the Frame House.
Restoration projects continued from 1986 though 2001 when interior restoration was partially complete, in which 20th century fixtures and alterations have been removed and older features exposed. The scope of project included authentic restoration and adaptation for meeting and reception facilities, historical displays, offices, rest rooms, and light food service.
In recent years, a major stabilization project was undertaken, and most significantly, the upper two floors have undergone transformation into offices. The construction was executed as adaptive re-use project, and all significant historical components have been carefully encapsulated so the modern efforts are fully reversible.
The site provides excellent insights into the span of Maryland and American history and efforts to restore and tell the Carroll house story are continuing.
