CONVERSION plans for classrooms at a former school have been scotched because the building is within the Green Belt. Redwaters Construction wanted to convert two classrooms at the Kings Park Christian Centre -- formerly Leigh CE High School until it closed a decade ago -- creating four houses, and 12 flats. But Wigan's development control committee over-ruled a planning department recommendation to approve the scheme. The proposals had raised a number of objections from people living nearby.
