High-tech architecture, also known as Late Modernism or Structural Expressionism, is an architectural style that emerged in the 1970s, incorporating elements of high-tech industry and technology into building design. High-tech architecture appeared as a revamped modernism, an extension of those previous ideas helped by even more advances in technological advancements.

                    The Leslie L. Dan Pharmacy Building at the University of Toronto is one example of high-tech architecture.

                                  The HSBC Hong Kong headquarters is one example of high-tech architecture.

                                       Torre Agbar in Barcelona is another example of high-tech architecture.

- Exposed structural elements (trusses, tie rods, struts, etc.) often creating a sort of "exoskeleton".
- tensile support by cables (often with a tented roof)
- extensive use of glass on exterior
- exposed technical features, such as air vents (especially in works by Richard Rogers)
- space frames and other structural networks
- glass elevators
- elevator shafts exposed revealing the mechanical features
- conspicuous presence of recent technological innovations
- large atriums (some are very long like gigantic hallways)
- usually lack of reference to historical styles (a continuation of modernism), but many postmodern buildings have incorporated elements of structural expressionism
- skyways between buildings and skybridges (skyways that are very high)
- many have a metallic finish which is most commonly silver or grey; non-metallic white is also very common; black is more common than in most architectural styles
