John Giles was a British architect. He was born in Lincoln, probably in 1830, and his family came from Branston near Lincoln. He was articled to the Lincoln architect Pearson Bellamy. He had moved to London by 1859 and with Pearson Bellamy entered a number competitions for major public buildings. Of these only one, for Grimsby Town, was successful. In London he was responsible for a number of major projects including the Langham Hotel. He also started in 1869 on the design of hospitals with the Infirmary to Hampstead Union Workhouse. After a short period of partnership with Lewis Angel, when Stratford Town Hall was built and with Edward Biven, by 1873 he was in partnership with Albert Edward Gough. They were joined in the practice by J E Trollope and they became involved in the design of Arts and Crafts housing in London's west end. Giles had business interests in the City of London and was noted in 1867 as being a Director of the Imperial Guardian Life Insurance Company.

Bellamy and Hardy was an architectural practice in Lincoln, England, that specialised particularly in the design of public buildings and non-conformist chapels. Pearson Bellamy had established his own architectural practice by 1845 and he entered into a partnership with James Spence Hardy in June 1853. Both partners had previously worked for the Lincoln architect William Adams Nicholson. Hardy was described as "Chief Clerk" to Nicholson. Hardy joined Pearson Bellamy immediately after the sudden death of Nicholson. As all known architectural drawings by the practice are signed Pearson Bellamy, it is likely that Bellamy was the architect and Hardy was the administrator in the practice. The partnership lasted until 1887. Bellamy continued to practise until 1896.
