When HSBC Private Bank took over the former Conservative Club they wanted to change it into a modern financial services building without losing its intimate historic character. This commission consisted of the complex restoration of the grade II listed building on St James's Street and the addition of an independent state-of-the-art office building. The central challenge involved integrating these two very different structures.
A full height atrium was introduced between the two buildings to provide an interface between the historic and the contemporary. From here there are views from each building into the other. The sumptuous historic interior can be glimpsed from glass lifts that rise up through the atrium. The exact point of intersection is defined by the rear wall, which on one side has classical round arches and on the other modern square arches.
The glazed dome roof of the listed building was restored and, above it, a new glass roof was added creating a double height gathering space; a focal point from which all aspects of the scheme can be viewed.
