Jersey

Has anyone in Jersey been allowed to do this?

The island's planning register, searched the way someone with a plan searches it: by the kind of work, by where, and by your own words. 3,402 applications are in here.

The ones that were refused

More useful than the approvals: this is what the island would not accept.
