High Tech Architecture: The Inside-Out Movement That Redefined Modern Building

High Tech architecture, also known as Structural Expressionism, emerged in the UK in the 1970s, emphasizing visible structural and mechanical systems. Key pioneers include Norman Foster, Richard Rogers, Nicholas Grimshaw, Michael and Patty Hopkins, and Renzo Piano. The movement's origins trace back to Joseph Paxton's Crystal Palace (1851). Reyner Banham coined the term 'High Tech' in his 1966 book The New Brutalism. Notable examples include Centre Pompidou (1977), Lloyd's of London (1986), HSBC Headquarters (1986), Kansai International Airport (1994), Reichstag Dome (1996), Millennium Dome (1999), Eden Project (2000), and 30 St Mary Axe (2003). Women like Su Brumwell, Wendy Cheesman, and Patty Hopkins played foundational roles but received less recognition. The movement's principles—modularity, lightweight cladding, prefabrication—are now standard. Recent deaths of Rogers (2021), Hopkins (2023), and Grimshaw (2025) mark the passing of the foundational generation.
