What this refusal means

Welwyn Hatfield refused this application for the reasons on the decision notice; only the applicant can appeal, and refused schemes often return in revised form. More in our guide to what happens after a planning decision.

About prior approval applications

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.
