Hi, I have bought a site that comes under the borough of Croydon. I have been granted planning for 2 two bed flats. As this doesn't come under a self build project I will have to pay CIL. On the site there are garages/storage. Can you offset the floor area of the existing against the new project. I have looked on the Croydon website and not much help. have emailed them and no joy with any info. anyone come across this. Thanks
