English architect. He made a major contribution to the development of Hampstead Garden Suburb, London, from 1908, where he designed many houses, including gabled work in Denman Drive. He also designed the handsome curved terraces of shops and apartments in Golders Green Road that demonstrate the early C20 change of style from vernacular revival to Neo-Georgian. In collaboration with Frederick Etchells (the translator of Le Corbusier's works into English), Welch, with Nugent Francis Cachemaille-Day (1896–1976) and Felix J. Lander (1898–1960), designed the pioneering International Modern Crawford's Office Building, High Holborn, London (1930), with long bands of windows subdivided by steel mullions, much influenced by the Weissenhofsiedlung.
