Art directed by Ralph Berger and Albert S. D'Agostino, The Boy With Green Hair (Joseph Losey, 1948) substitutes the architecture of houses for characters. When the Boy, suffering the loss of his parents during the war, is sent to various family members for custody, instead of showing the characters, Losey ingenuously opts to show only shots of the houses they live in: baroque, modernist, urban, suburban.
This is, arguably, one of the most clever examples of integrating architecture into narrative in classical Hollywood.
