Moved into our new build home 7 years ago with a license across the driveway that in the future they may use it to access the field next to us for further development. They cannot build on said field at present due to presence of a industrial works that has a ‘blast zone’. We would love to extend driveway it even add a garage to it but obviously can’t risk this if they were to decide to run a road through there! Anyone any experience on a situation like this? Thanks
