  Erection of new garden outbuilding

  Decided 1 Aug 2024 Householder

Watford granted permission on 1 April 2025, subject to any conditions on the decision notice. Work must normally begin within three 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.
