Blue House (藍屋) refers to a 4-storey balcony-type tenement block located at 72-74A Stone Nullah Lane, Wan Chai. It is named for the brilliant blue colour painted on its external walls. It is one of the few remaining examples of Tong Lau of the balcony type in Hong Kong. All the upper floors of Blue House, apart from 72 Stone Nullah Lane, are of timber structures. The two wooden stairs, with all the original elements intact, are well maintained.
