This application is at appeal, which passes the decision from Welwyn Hatfield to the planning inspectorate, and the outcome will replace the council's decision. More in our guide to what happens after a planning decision.

Prior approval applies where permitted development rights already grant the principle of the work, leaving the council only the specific matters the rules name, commonly within 56 days. More in our guide to planning application types.
