Despite the success of saving Johnson’s masterpiece, other less well-known Modernist buildings across the United States are now facing demolition. The main threat comes from skyrocketing land prices; these landmark buildings are prized more for their land than their architecture, say design curators and preservation experts nationwide. Barry Bergdoll, chief curator of architecture and design at MoMA, believes that for every Modernist structure saved, two are torn down and many are altered. Other experts believe the number of modernist buildings demolished could be considerably higher.
