ABOVE: The Mann Island development scheme on Liverpool's historic waterfront

The Mann Island apartment scheme in Liverpool was also singled out by the Carbuncle Cup team for its "wrist-slashingly awful" design. The wedge-shaped, granite-clad development was led by Broadway Malyan for £120 million and created 363 luxury apartments on Liverpool's historic waterfront. BD said the contentious project "completes the desecration of that city’s once great waterfront."

Two other buildings - the "grimly utilitarian" Firepool Lock in Taunton and Shard End Library in Birmingham - complete the 2012 Carbuncle Cup shortlist. The buildings will be assessed for "their relative awfulness" over the next month, with a winner announced on August 24.
