If you download it to size 100% and look where the new public lavatories are to be (at the back of Debenhams across Kings Road from Ottewill Art) you will see the following distances in cms from the Corn Exchange:
Current temporary loos in School Yard/Nelson Road 18
Angel Hill loos 13
Old St Andrews St loos 9
Future loos 7
In other words, the new public lavatories will be nearer than the old ones, just over half the distance of the Angel Hill ones and 40% of the distance of the existing temporary ones.
