Lui Seng Chun is a four-storey tong lau (literally meaning Chinese-style building, the local term for Hong Kong shophouse typology) located on a triangular site in Mong Kok, Kowloon. It was built in 1931 and owned by Lui Leung (1863-1944), one of the founders of The Kowloon Motor Bus Company (1933) Limited. The Lui family ran a Chinese medicine shop on the ground floor and lived on the upper floors. The medicine shop was closed a few years after Lui Leung passed away in 1944. In 2003, the Lui family donated the building to the Hong Kong Government for preservation. The donation was unprecedented in Hong Kong.
Lui Seng Chun was designed by W. H. Bourne. The building is of neo-classical style mixed with Art Deco elements by sweeping horizontal lines and robust classical elements. Its main front elevation is in a curved design.
Under Batch I of the Revitalising Historic Buildings Through Partnership Scheme, Lui Seng Chun has been revitalised as a Chinese medicine and healthcare centre operated by the Hong Kong Baptist University since 2012. Apart from resuming the original function of Lui Seng Chun as a medical-related facility, the original architectural form and elements such as granite columns, terrazzo exterior wall, flooring tiles, and staircase are well preserved. Lui Seng Chun is a testimony to the history of a well-respected family, including the economic activities of their Chinese medicine shop around the Second World War.
Lui Seng Chun was declared a monument in 2022.
