A copper-clad concave tower block designed by London architect RTKL is planned for Liverpool. It forms the centrepiece of an application for a £100m scheme from developers Ballymore Properties and Merepark. If successful, the tower, which will contain 400 flats, will be built on a vacant site behind Central Station. Completion is planned for 2006, two years before Liverpool becomes European Capital of Culture. Mott MacDonald is civil and structural engineer, Formans the services engineer and EC Harris the quantity surveyor.
