High-tech architecture, also known as structural expressionism, is a type of late modernist architecture that emerged in the 1970s, incorporating elements of high tech industry and technology into building design. High-tech architecture grew from the modernist style, utilizing new advances in technology and building materials. It emphasizes transparency in design and construction, seeking to communicate the underlying structure and function of a building throughout its interior and exterior. High-tech architecture makes extensive use of aluminium, steel, glass, and to a lesser extent concrete (the technology for which had developed earlier), as these materials were becoming more advanced and available in a wider variety of forms at the time the style was developing – generally, advancements in a trend towards lightness of weight.
High-tech architecture focuses on creating adaptable buildings through choice of materials, internal structural elements, and programmatic design. It seeks to avoid links to the past, and as such eschews building materials commonly used in older styles of architecture. Common elements include hanging or overhanging floors, a lack of internal load-bearing walls, and reconfigurable spaces. Some buildings incorporate prominent, bright colors in an attempt to evoke the sense of a drawing or diagram. High-tech utilizes a focus on factory aesthetics and a large central space serviced by many smaller maintenance areas to evoke a feeling of openness, honesty, and transparency.
