Back-to-back houses are a form of terraced house in which two houses share a rear wall (or in which the rear wall of a house directly abuts a factory or other building). Usually of low quality (sometimes with only two rooms, one on each floor) and high density, they were built for working class people and because three of the four walls of the house were shared with other buildings and therefore contained no doors or windows, back-to-back houses were notoriously ill-lit and poorly ventilated and sanitation was of a low standard.

Houses of this type had become common in Victorian English inner city areas, such as those of Birmingham, Bradford, Leeds, Liverpool, Manchester and Salford, and Nottingham. In Leeds, this style of terrace continued to be built right up until 1937 when it was decided that houses should be of a higher quality.

The advent of council housing after the First World War resulted in councils organising programmes of slum clearances which were all part of post-war redevelopment programmes. These procedures saw the beginning of mass demolition of back-to-back houses in the 1920s. The process started again in the 1950s and continued through the 1960s, and by the 1970s the vast majority of back-to-back houses in England had been cleared.^{[citation needed]}
