A DEVELOPER has once again been told it cannot build housing on the canalside site of a derelict garden centre. Hartley Developments has planned to build homes on the former Hirst Wood Nursery in Saltaire, just off the banks of the Leeds Liverpool Canal, for several years. But Bradford Council has refused two applications for the site, with planning officers arguing that the plot, in the Green Belt, on the edge of a World Heritage Site and next to the canal Conservation Area, was not suitable for such a development. Last year the Hartley Group appealed against the most recent refusal, arguing the site had previously been developed, and the homes would not harm the area.
