Blue House is a 4-storey balcony-type tenement block built in the 1920s at 72-74A Stone Nullah Lane, Wan Chai, in Hong Kong. Its name was derived from the brilliant blue colour painted on its external walls. According to historians, the structure's bright hue was due to the fact that only blue paint was available during the time of construction and not a deliberate aesthetic decision.
The building is one of the few remaining examples of "Tong Lau" balcony type structures in Hong Kong and is classified as Grade I historic building. It is part of a HK$100 million plan, unveiled by the Housing Society and the Urban Renewal Authority, to preserve nine Chinese-style buildings in Wan Chai that were constructed during the 1920s.
Most of the structure's original elements are still intact and well maintained. There are still residents occupying some parts of the building but an area is now housing the Hong Kong House of Stories (formerly Wan Chai Livelihood Museum), a community project which organises exhibitions on local culture and cottage industries. Hong Kong House of Stories also offers visitors a glimpse of Blue House’s typical living quarters. The museum is open from 11am to 6pm daily, except Wednesdays and public holidays, and admission is free.
To get to the Blue House, take MTR to Wan Chai Station, get out at Exit A3. Walk along Tai Yuen Street to Queen's Road East, then turn left to Stone Nullah Lane.
