Kansas City Museum is working on a multi-year project with architect International Architects Atelier to transform the late lumber baron Robert A. Long’s estate into one of the leading city museums in the county.  

The first phase, Corinthian Hall, Long’s Beaux-Arts style mansion, reopened in 2021, after a $22 million, seven-year renovation. Most recently a science museum, it now houses historical and cultural exhibits about how the Longs lived, and the city’s history, from pre-European contact to the present.  

IMEG will provide mechanical, electrical, plumbing and fire protection engineering services for the $8.3 million second phase of projects. 

They include: 

• The Conservatory – formerly used as a planetarium – will be restored into what the museum calls a “light-filled sacred space called JewelHouse.” 
• Renovating the property’s Carriage House into a gallery and office space. 
• A below-grade cooling tower will be turned into an interactive sculptural exhibit called Skyspace, which features a timed light program that interacts with natural light coming in through an oculus in the ceiling.
