Horsham has decided this application; the outcome above is the register's own wording and the decision notice on the council portal carries the detail. 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.
