Structural Expressionism, also known as High Tech Modernism, was a reaction to Miesian ideals of buildings. Structural Expressionist buildings incorporate the ideals of interchangeable prefabricated parts, flexibility in design and economy of construction. The main concept behind the design is using the structural components to dictate the aesthetic of the building. Oftentimes, structural elements are exposed and employ innovative approaches to structural stability. Engineering creates new possibilities in building design.

Primary Stylistic Features
  • Exposed or visible structural elements inside and out.
  • Emphasis on the industrial materials.
  • Functional building components are exposed.
Secondary Stylistic Features
  • Interior spaces are adaptable.
  • Detached frames.
  • Exposed trusswork.
  • Extensive use of glass.
  • Highly complex shapes.
  • Metallic.

Evaluation Considerations

Structural Expressionist buildings will be considered for their individual eligibility.  To be considered eligible, Structural Expressionist buildings should retain all the primary stylistic features and some secondary features to exemplify materials, design, workmanship, and association.  This recent past resource should retain a high level of integrity and be an important expression of the style in the context of the state or local area.
