An unprecedented public and private partnership coupled with an extensive document search and archaeological excavation provided the foundation for a comprehensive renovation of Morven that began in 1999.

The program restored historic features of the grounds, including an 18th-century horse chestnut walk and a colonial revival garden. The buildings were returned to original colors, 20th century alterations were removed, and historic features, such as the renowned parquet floors, were re-installed.

An extensive nine-zone environmental system allows the museum to individually regulate temperature and humidity in each room, and new security, lighting, fire suppression, and handicap-accessibility systems place Morven at the forefront of industry standards for museums.
