High-tech architecture, also known as structural expressionism, is a style of modern architecture that emerged in the 1970s. It is characterized by the use of industrial materials, such as steel and glass, and an emphasis on technology and innovation in design.


The origins of high-tech architecture can be traced back to the early 20th century and the works of architects such as Le Corbusier, who envisioned buildings as “machines for living”. However, it was not until the 1970s that the term “high-tech” was coined by the architectural historian Reyner Banham, who used it to describe the work of architects such as Richard Rogers, Norman Foster, and Renzo Piano.

These architects were influenced by the emerging technological and industrial advancements of the time and sought to incorporate these into their designs. They emphasized the use of exposed structural elements, such as beams and ducts, and integrated building services, such as air conditioning and plumbing, into the design.

The most iconic high-tech buildings of this era include the Pompidou Centre in Paris by Rogers and Piano, the Willis Faber and Dumas Headquarters in Ipswich by Foster, and the HSBC Building in Hong Kong by Foster and Partners.


High-tech architecture continued to evolve in the 1980s and 1990s with architects such as Santiago Calatrava and Frank Gehry pushing the boundaries of what was possible with new technologies and materials. Today, high-tech architecture continues to influence contemporary design, particularly in the areas of sustainable architecture and smart building technologies.

1) Characteristics of High-Tech Architecture

The emphasis on technology and innovation in high-tech architecture is one of its defining characteristics. Architects who follow this style often use the latest technologies and construction methods to create innovative and visually striking buildings. This includes the use of computer-aided design (CAD) software, digital fabrication techniques, and 3D printing.

Another key feature of high-tech architecture is the use of industrial materials such as steel and glass. These materials are often used for their strength and durability, as well as their modern and sleek appearance. Steel, for example, can be used to create large spans and cantilevers, while glass allows for transparency and natural light to flood into buildings.

High-tech architecture also emphasizes the exposure of structural elements in buildings. Instead of hiding structural components behind walls and ceilings, architects often choose to expose them as a design feature. This can include beams, columns, and ducts, which are left visible to create an industrial, “unfinished” aesthetic.

Finally, high-tech architecture often integrates building services into the design of a building. This means that components such as heating, ventilation, and air conditioning systems are incorporated into the building’s structure rather than being added as an afterthought. This allows for a more efficient use of space and resources, as well as a more streamlined and cohesive design.
