The Lambeth Workhouse was a workhouse in Lambeth, London. The original workhouse opened in 1726 in Princes Road (later, Black Prince Road). From 1871-1873 a new building was constructed in Renfrew Road, Lambeth.. The building was eventually turned into a hospital, and is now occupied by the Cinema Museum.
The new workhouse was built for 820 inmates, divided by sex into two groups. It cost £64,000 to build, replacing the older workhouse in Princes Street.
The water tower of the Renfrew Road workhouse is Grade II listed. In 2011, it was converted into an unusual residence with a lift and observation gallery converted from the large water tank on the eighth floor. The new interior was designed by Sue Timney and the development was featured on the television show Grand Designs.
