They are the plots of land that form the 'final pieces of the jigsaw' in the regeneration of Ancoats – but no one knows who owns them.
Most of the land which is primed for development in the area has already been bought up. However, the owners of three small plots on the Phoenix Ironworks site remain unidentified, eight years after developer Manchester Life first started buying up land behind Beehive Mill, where 256 homes are set to be built.
The company - which is owned by Manchester council and Manchester City FC owner Sheikh Mansour - says that 'all avenues have been exhausted' in efforts to trace the freeholders of the land, which it already has 811-year leases for.
