and materials technology expertise. In April 2015, a $25 million interior and exterior restoration began. The restoration focused on structural improvements such as replacing the majority of the building's 16 separate flat roofs. The restoration also addressed decorative and environmental improvements to the building. Unity Temple closed to the public in June 2015. Restoration work was completed in June 2017 and the building reopened for tours as of July 1, 2017. The building is closed to tours on Sundays, when the Unitarian Universalist church that calls the building home has its day of worship, but offers tours on other days of the week. The Unity Temple Restoration Foundation offers a full calendar of artistic and educational programming. In 2018, the restoration of the temple received an award for excellence by the American Institute of Architects, Chicago chapter, and in 2019 was awarded the Urban Land Institute - Chicago Vision Award for historic restoration.
