Common Mistakes When Applying for Planning Permission in Wessex

The planning system in Wessex is not trying to stop you building a porch. It is, however, keenly interested in where that porch goes, what it is made of, and whether anyone will be able to see it from the lane.

Most refusals, and even more of those long silences from a planning office, come down to a small number of avoidable mistakes. Conservation areas, listed buildings and the green belt account for a good share of them. None of these designations means "no". They mean "show your working". Here is where homeowners most often come unstuck, and how to get it right first time.

Assuming permitted development rights always apply

Permitted development rights let you carry out certain extensions, outbuildings, fences and roof alterations without a full application. They are genuinely useful and genuinely not universal.

In a conservation area, some of those rights are withdrawn. Cladding the outside of a house, certain side extensions, some rear roof extensions and fences over a metre high next to a highway all need permission where they otherwise might not. A council can remove more rights through an Article 4 direction, which is common in older towns and villages across Wiltshire, Dorset, Somerset and Hampshire. Listed buildings have no permitted development rights at all: every alteration needs consent.

Check your council's online constraints map before you sketch anything. If the position is unclear, apply for a lawful development certificate. It is a written, binding confirmation that what you are doing does not need permission, and it is worth having if you ever sell.

Confusing the green belt with "the countryside"

Green belt is a specific planning designation, not a synonym for rural. Plenty of land outside a town is simply countryside, with different rules. Much of what people assume is green belt around Wessex's towns is not, and some land they assume is unconstrained very much is.

Where green belt does apply, new buildings are normally treated as inappropriate development and need very special circumstances to be justified. Extensions and replacements can sometimes be acceptable, but only where they do not have a greater impact on the openness of the green belt than what is already there. Scale, height, bulk and visibility all count. Gaps between settlements matter too.

Remember that green belt is rarely the only constraint. National Landscapes, flood zones, tree preservation orders, listed parkland and settlement boundaries all sit on top of one another, and a case officer will consider every layer that touches your site.

Treating listed building consent as a formality

Listed building consent is a separate application from planning permission. You can need one, both, or occasionally just one. It covers interiors as well as exteriors, and it can extend to structures within the curtilage of a listed building, which is how a garden wall or an old barn catches people out.

Carrying out works to a listed building without consent is a criminal offence, and enforcement is not subject to the usual time limits. There is no clever way round this. If your property is listed, get advice from an architect or surveyor with conservation accreditation before you take down so much as a partition. That conversation is far cheaper than an enforcement case.

Submitting drawings that don't answer the questions

Applications are refused, or delayed for weeks, because the paperwork does not tell the case officer what they need to know. A quick checklist of what usually has to be there:

  • Scaled existing and proposed floor plans and elevations, not estate agent floorplans
  • A site plan and block plan with the red line drawn accurately around the correct land
  • Materials specified properly. "White render" is not a specification; name the product or match a sample
  • A heritage statement for listed buildings and most work in conservation areas
  • A design and access statement where one is required
  • Arboricultural information if trees are nearby, and six weeks' written notice for works to trees in a conservation area
  • Flood risk or drainage detail where the site needs it
  • Ecological surveys if there is any chance of protected species, with bats in roofs the classic example

Send too little and the application may be declared invalid, which starts the clock again. Send a vague heritage statement and you invite a request for more information that can add a month.

Surprising the neighbours and the parish council

Parish and town councils are statutory consultees and their comments are read carefully. Neighbours are not consultees in the same formal sense, but their objections shape how a case officer views overlooking, loss of light, parking and noise.

Talk to both before you submit. Show them the drawings, walk the boundary, and listen. Most of the objections that sink small applications are about a window, a boundary or a driveway that could have been shifted two metres at the drawing stage. A redesign in week one costs nothing; a refused application and an appeal costs a great deal.

Stopping once permission is granted

An approval is not the finish line. Almost every decision notice comes with conditions, and some must be discharged before you start work. Begin building before discharging a pre-commencement condition and you risk invalidating the permission altogether.

Read the notice properly. Check the time limit for starting, which is usually three years but can differ, and look for any Community Infrastructure Levy or legal agreement obligations. Building regulations approval is a completely separate process, and starting without it creates its own problems later.

A short sequence that saves weeks

  1. Check every constraint on the site using the council's mapping tool and the conservation area appraisal.
  2. Work out what is already permitted, and get a lawful development certificate if the answer is uncertain.
  3. Ask for pre-application advice, and ask for it in writing.
  4. Commission drawings and statements that answer the questions above.
  5. Speak to neighbours and the parish council before submitting.
  6. Once approved, discharge conditions and get building regulations sign-off on schedule.

If your property is listed, sits in the green belt, or falls within a conservation area, an hour with a planning consultant or conservation architect is usually the best money you will spend on the project. This is general guidance rather than legal advice, and where there is any risk of enforcement, take proper professional advice before you start.
