This Venetian Gothic tower topped with an iron water tank was transformed last year into a private home. Lambeth Workhouse Water Tower was built in 1877 to serve the Lambeth Workhouse and Infirmary, a onetime home to Charlie Chaplain that became Lambeth Hospital. Little is left of the main buildings, but the water tower stood untouched for years until the owners bought it, discovering 2,000 dead pigeons inside, according to My Modern Met.
After eight months of construction and rehabilitation, it's now a four-bedroom home. The water tank living room area topping the tower has black windows blending with the black iron from below. From the inside, those windows offer 360 degree views to modern London.
