John Dixon Butler (December 1860 – 27 October 1920) was a British architect and surveyor who had a long, professional association with London's Metropolitan Police. During his 25-year career with the police, he completed the designs and alterations to around 200 police buildings, including ten courts; as of 2022, about 58 of his buildings survive. Historic England describes him as "one of the most accomplished Metropolitan Police architects" and have included around 25 of his buildings on the National Historic List of England and Wales.
Dixon Butler was born in London and studied architecture under Richard Norman Shaw, with whom he would later work on the designs for Canon Row Police Station (1898), and the Scotland Yard (south building) (1906) on London's Embankment. Dixon Butler took over the role of architect and surveyor to the Metropolitan Police from his father in 1895. Dixon Butler's designs were usually in a domestic style, sensitive to the context of newly-developed suburban areas in which stations were often located, but with strong municipal qualities such as iron railings, inscribed lintels identifying the building as a police station, and other stone dressings.

Elected a fellow of the Royal Institute of British Architects (RIBA) in 1906, Dixon Butler worked up until his death in 1920.

Early life
Dixon Butler was born in December 1860 at 11 Redcliffe Gardens, Chelsea, London. He was the only son and the second of two children to John Butler (1828–1900), an architect and surveyor, and his wife, Hannah Deavin. Dixon Butler studied at University College London and then the Architectural Association, before being articled to his father, from whom he learnt about the design and planning of police buildings.

Dixon Butler's father was appointed as the Surveyor to the Metropolitan Police in 1881; upon his retirement in 1895, Dixon Butler succeeded him in the role. Both father and son worked under Richard Norman Shaw on the designs for Scotland Yard; Butler on the North building, Dixon Butler on the South. The position was later reversed at Canon Row on London's Embankment, on which Dixon Butler was the lead architect and Norman Shaw acted as consultant.
Surveyor to the Metropolitan Police
The Metropolitan Police Force Surveyorship was established in 1842; the force's first purpose-built station was built at Bow Street, erected two years after Sir Robert Peel's Metropolitan Police Act of 1829. There was a boom in police stations during the 1880s following the political unrest of that decade and high-profile events such as the Whitechapel Murders. Cherry, O'Brien and Pevsner, in their London: East volume of the Buildings of England series, record Dixon Butler's "unique" riverside police stations for the Thames River Police, founded in 1798 to combat piracy, including his station at Wapping which now houses the Thames River Police Museum.
Under Dixon Butler, after 1895, police station interiors in London became more domesticated and an effort was made to make them more approachable to the public, including their relocation into more public areas. After a violent demonstration outside the station in Bow Street, the Metropolitan Police decided to have separate entrances at their stations for constables, away from the public, and to have officers live at the stations under the supervision of senior colleagues. Extra provisions were also made for the care of prisoners, including the introduction of ablution areas and exercise yards. Externally, Dixon Butler was careful to design them in a similar style to the surrounding, newly developed suburban areas in which they served.
Dixon Butler's designs included features which give his buildings strong municipal accents, such as iron railings and lintels inscribed "Police" or "Police Station", set in stone dressings, and his frequent use of elaborate consoles to doors and windows. These elements give his designs their architectural quality creating a "characteristic type which can be recognised all over London". Historic England describes him as "one of the most accomplished Metropolitan Police architects".
