Hart & Waterhouse was an architectural partnership formed by Alfred Henry Hart (1866-1953) and Percy Leslie Waterhouse (1864-1932) in London, England in 1902.
Following the death of Waterhouse in 1932 Hart became the sole partner in the practice which he continued to run until 1938, retaining the original title of the business.
Projects by the practice included offices for the Canada Emigration Department at 9 Charing Cross, London in 1902; Parkside at Albert Gate, London in 1908; additions to Cuddesden College, Oxford in 1909; and an office building for Willing Advertising at 356 Gray's Inn Road, London in 1909.
