Collcutt & Hamp [also known as T.E. Collcutt & Stanley Hinge Hamp] was an architectural partnership formed in London, England in 1906 by Thomas Edward Collcutt (1848-1924) and Stanley Hinge Hamp (1877-1968). Philip Armstrong Tilden (1887-1956), who had been articled to Collcutt, joined the practice which was renamed Collcutt, Hamp & Tilden. By 1917 Tilden had withdrawn from the partnership to set up his own office, and the practice reverted to its original name.
Following the death of Collcutt in 1924, Hamp continued to run the practice with the title unchanged even after John Francis Watkins joined as a partner. The partnership with Watkins was dissolved in 1946, however Hamp again continued to run the business for some years retaining the original name.
Architectural projects by Collcutt & Hamp included the rebuilding of the offices of the Peninsular & Orient Steamship Co. in Leadenhall Street, London; offices for Messrs Liebig Ltd. in Queen Street, London; alterations and additions to the Savoy Hotel in Strand, London (1910); alterations and additions to Claridge's Hotel in Brook Street, London; premises for Hamley Bros. Ltd, in Regent Street, London; premises for Messrs Fuller Ltd., in Regent Street, London; a science building for Mill Hill School in London; the Gate of Honour at Mill Hill School, London; the London School of Tropical Medicine at Endsleigh Gardens, London; King George's Sanatorium for sailors at Bramshot, Hampshire; alterations and additions to Roffey Park in Horsham, Sussex; Davenies Farm at Beaconfield, Buckinghamshire; and Leith Hall and Public Library at Leith, Edinburgh, Scotland (1926).
