Mayslake Hall Exterior Rehabilitation

Planning Project

Mayslake Hall 

Designed by renowned Chicago architect Benjamin H. Marshal, the Tudor Revival style Mayslake Hall in Oak Brook is on the National Register of Historic Places and is one of the last remaining examples of the country estates that dotted DuPage County between 1880 and 1924. In 1926, the estate was sold to the Franciscan Province of the Sacred Heart, who operated the estate as a retreat house, adding a retreat wing and chapel to the west side of the mansion. The District acquired the estate from the Franciscans in 1993.

The mansion is nearly 100 years old, and many of the original materials used in its construction are in need of repair or replacement. In 2020, the District hired an architectural consultant to perform a comprehensive assessment of the building envelope to identify structural issues and material deficiencies, which contributed to water damage and other threats to the historic mansion.

Based on the results of that assessment, a proposed treatment strategy was developed to address major issues with the building’s exterior, including improvements to the roofing systems, wood and stucco façades, brick and limestone masonry, foundation, surrounding site drainage, and accessibility.


The District hired architectural and engineering consultants to prepare construction plans according to the treatment strategy in 2021.

Construction of the improvements is anticipated to begin in spring 2022 with estimated completion in early 2023.
