Terrace Hill
Mansion —
Restoration &
Rehabilitation
Terrace Hill has served as the Iowa Governor's residence for nearly 50 years. Challenges included restoring lost historic details while preparing the building to serve future generations of Iowans and their Governors. Besides housing the Governors and their families, the mansion serves as official reception space for dignitaries, and is open to the public as a museum.
Built in 1869, Terrace Hill has served as the Iowa Governor's residence, museum, and host to official state functions since 1976. RDG introduced a sprinkler system into the historic fabric, updated the finishes in the Governor's apartment, and completed extensive work on the mechanical, electrical and data systems. Historic photographs and other sources were consulted on the exterior restoration phase, which included replacement of the distinctive polychromatic slate roof and copper gutters, fabrication of missing wood elements, and masonry repair and repointing. Work on the original Carriage House included masonry repair and exterior woodwork repairs.
