Streatham Street is a street in the London district of Bloomsbury, running between New Oxford Street and Great Russell Street. In the 19th century, the street was on the border of the "rookery" of St Giles, a slum, and became the location for new accommodation, which reformers planned would replace the slums.

Parnell House was built in the 1850s by Henry Roberts. Originally constructed by the Society of Improving the Condition of the Labouring Classes, the building was designed to reform the living conditions of slum residents.^{[verification needed]} Whereas whole families had lived together in one room, now they could enjoy a more spacious living space.^{[citation needed]} The Streatham Street apartments were the first multi level domestic building in the world. Subsequent buildings were erected by George Peabody, and Streatham Street was taken over by the Peabody Trust and modernised in later years.^{[citation needed]}
