Yes, and for most houses it's the ordinary planning route. Only a handful of buildings are listed. No conservation area covers the village. The neighbours put in planning applications all the time. The strictest check on your extension is the clay underneath it.
Wootton has 15 listed buildings. None is Grade I, 1 is Grade II* and 14 are Grade II. Listing covers the whole building, inside and out, so almost any change that affects its character needs listed building consent on top of normal planning. That includes windows, walls, roofs and interior features. If your house is one of those 15, the council's conservation officer has a say in every change. In a village of around 2,370 homes, most buyers will never deal with that.
The planning register shows people are getting on with it. From April 2024 to June 2026, 733 planning applications were logged for the area, 310 of them in the last twelve months. That's the volume of a village where extending the bungalow is a normal thing to do on retirement. The numbers show how often people apply. They don't show how many succeed.
The British Geological Survey gives Wootton a shrink-swell class of 3, and every postcode in the area falls into it. Shrink-swell means clay soil that expands when wet and contracts in dry summers. A new extension's foundations may need to go deeper than a standard trench, and a structural engineer should assess the ground before the builder quotes. That isn't a reason to abandon the plan. It's a line in the budget, and it's better to find out now than after the first dry summer puts a crack between the old wall and the new.
With no conservation area and very few listed buildings, most houses here keep their normal permitted development rights. Many modest rear extensions, loft conversions and outbuildings can go ahead without a full planning application, within the national size and height limits. Check that your particular house hasn't had those rights removed by a condition on an earlier planning permission, and ask for a lawful development certificate if you want written certainty before the builders start. Anything bigger or more visible goes through a normal householder application.
Freedom to extend is one of Wootton's real strengths. Apart from 15 listed buildings, planning here is light. The main thing to plan for is the clay, not the council.
