Roof work near Chichester Harbour National Landscape: what changes?

Chichester Harbour first received national protection on 4 February 1964, when it was labelled an Area of Outstanding Natural Beauty. In 2023 every such area in England was relabelled a National Landscape, so the same stretch of shore now carries the newer name. The Chichester Harbour Conservancy counts it as one of 34 National Landscapes in England, designated under the National Parks and Access to the Countryside Act of 1949.

A harbour view is not the same as being inside the line. Appledram, West Thorney, Prinsted and the part of the Fishbourne conservation area south of the A259 are recorded as lying within it. So is Emsworth, where the harbour's western arm ends. Emsworth is in Hampshire, which means its planning authority is Havant Borough Council, while the West Sussex shore answers to Chichester District Council.

Before assuming a rule covers your road, ask the right council whether your address sits within the boundary at all.

Under the planning Act, a job that leaves the outside look of a building essentially as it was is not counted as development, and a repair, or a re-roof in the same material, colour and profile, normally fits that description. The harbour designation does not bolt a separate permission on top.

Watch the words "like for like". Moving from natural slate to a concrete tile, or from clay to something that reads differently from the lane, changes how the house looks, and that is where a council may take an interest. A listed house, or a road under an Article 4 direction, shifts the answer again, so ask before you order materials.

Planning is one question and Building Regulations is another. Normally no application is needed where under 25 per cent of the building envelope and under 50 per cent of the roof is touched. Our page on roof work and Building Regulations sets out the whole picture, including the weight check for a covering that adds load.

This is where the designation bites. The planning rules class a National Landscape as article 2(3) land, under its legal name of an area of outstanding natural beauty, and a dormer extension is not permitted development on that land. A dormer on a harbour-side bungalow or cottage therefore needs a planning application, where the same dormer on an unrestricted street might not.

Roof windows are treated differently. The designation by itself does not remove the right to make other alterations to a roof, which is why a flush roof window can be an easier route than a dormer. Conditions still apply, such as obscure glazing on a side slope, and an Article 4 direction can remove the right, while a listed building also needs listed building consent.

Our guide to planning permission for a skylight walks through those conditions, and planning permission for roof work covers the wider rules.

Many older harbour-side buildings are listed. The Act forbids altering a listed building where the change reaches its special interest and no consent exists. A different covering, a rooflight or a lowered chimney can all call for listed building consent. Routine like-for-like maintenance is treated differently from alteration, and the council can tell you which side of that line your job falls on.

An Article 4 direction is how a council pulls specified permitted development rights out of a mapped area. Every direction lists exactly what it removes, so a neighbour's experience says little about your road. Ask the planning officers whether any direction covers your address and, if one does, which rights it takes away.

Parts of this coast also lie close to the South Downs, and a different authority decides there. Our page on roof planning in the South Downs explains who does what, so you do not ring the wrong office.

Planning questions go to the planning team at the council your home sits in: Chichester District Council for most of the West Sussex shore, and Havant Borough Council for Emsworth. Building control, where the work needs it, is handled by that council or by a registered building control approver of your choosing.

On a harbour-side job we start with a survey. Our surveyor photographs what is up there, then tells you in plain words if the roof needs mending, holding for now, or replacing, and why. We also tell you which consents the work is likely to meet. Where a Building Regulations notification applies, that paperwork is ours to deal with, and the written price is one total.

If you are weighing a view against a dormer or a new covering, bring that question to the survey. Once the pictures are on the table, the consent question is usually easy to settle, and you leave knowing which council desk to ring. Our roofing for Bognor Regis and the coast around it shows everything else we take on.
