A multimillion dollar expansion and renovation project is underway in Helena, Montana for the Montana Historical Society. Led by 80-year-old architecture firm Cushing Terrell, the Montana Heritage Center renovation project includes a 66,0000-square-foot expansion and the renovation of almost 67,000 square feet of existing space. The project will focus on the local land, with expansions appearing to emerge from the earth to reference the Lewis Overthrust, a geophysical event that helped define the state’s landscape with a collision of tectonic plates that drove one plate over another. The expansion project, to be completed in 2024, is 10 years in the making and will cost $52.7 million, nearly doubling the size of the existing 1952 Veterans and Pioneers Memorial Building.
