Opened in 1911 as the headquarters to the Royal Liver Group, the Royal Liver Building holds historical and cultural importance to the city of Liverpool, including Bertie and Bella, the mythical Liver Birds adorning its towers. The Liver Building was a pioneer of its time, being one of the first buildings in the world to be built using reinforced concrete. Today this iconic structure has been carefully managed by maintaining the building’s Grade I status as well as offering the facilities to service modern commercial users, cost effective, energy efficient lighting being of significant importance to the environmental operations of the building.
