-
Masonry Rehabilitation: Expert repairs along the Library Corridor, New House, Lounge, and key exterior walls.
-
Chimney Restoration: Structural repairs to the historic 80-foot boiler chimney.
Mike Colmey, Director of Buildings and Grounds, will post regular updates on our progress, so check back frequently to see the transformation in real time.
