Conwy granted permission on 28 July 2017, subject to any conditions on the decision notice. Work must normally begin within five years or the permission lapses. More in our guide to what happens after a planning decision.

An amendment application makes limited changes to a permission that already exists; anything beyond modest adjustment needs a fresh application. More in our guide to planning application types.
