On completion in 1964, it was very briefly Hong Kong's tallest commercial building, with 31 stories.
It is named after Wing On, a department stores and insurance conglomerate with a history dating back more than 100 years. Two other buildings along Des Voeux Road Central are also named after Wing On: Wing On Centre in Sheung Wan and Wing On Life Building in Central.
Each floor occupies around 11,000 square feet (1,000 m²).
The building currently houses the Hong Kong Branch of Public Bank Berhad, the Hong Kong Law Society, BOC Group Life Insurance and the local Consulate of Ghana as well as offices of Hang Seng Bank, whose old and new headquarters are next to Wing On House.
