The Hopkins House at 49a Downshire Hill is the common name given to the high-tech home and workspace in Hampstead, London (1976), designed by architects Michael and Patty Hopkins. It has been described as a "genuine icon of the High Tech movement". The house won a RIBA Award for Architecture in 1977 and a Civic Trust Award in 1979.

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, 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.
