You can extend most houses in Toddington, though there's more red tape than the village's post-war closes would suggest. The surrounding area has a long list of listed buildings. Ancient monuments are scattered across the fields around it. The clay under the hill moves with the weather. For anyone in a semi, the paperwork is ordinary, and for anyone in a listed cottage it becomes the main job.
Historic England lists 146 buildings across Toddington and the surrounding villages, 6 at Grade I, 2 at Grade II* and 138 at Grade II. Listing covers the whole building, inside and out, so changing windows, moving a wall or adding a rear extension to one of them needs listed building consent on top of any planning permission. The fabric often predates the planning system by centuries, and the council will expect it to outlast your plans for it as well.
There's one conservation area in the wider surrounding area, at Hexton. Inside a conservation area the council takes a closer interest in demolition, trees and anything that changes how a street looks, so some work that would normally go ahead without permission may need an application there. For the village of Toddington itself, conservation area rules are a smaller issue than listing.
The area also has 8 scheduled monuments, the strictest tier of heritage protection, which mostly matters to anyone whose land borders one.
Plenty of people extend here anyway. The planning records for the area hold 4,049 applications between April 2024 and June 2026, and 1,748 of them came in the last twelve months. Those figures tell you how often people apply. They don't tell you how often permission is granted. Nobody here is short of ideas for a kitchen extension.
The British Geological Survey puts the ground here at class 3 for shrink-swell, its moderate band, and about 86% of the area's postcodes reach that class or higher. In plain terms, clay that swells when wet and shrinks when dry, under a village that sits on the Gault Clay beneath its hill. For an extension, that usually means deeper foundations than a builder might quote off the cuff, and attention to trees near the new wall. Get a structural engineer to look at the ground before committing to the extension budget, because on this clay the foundations are part of the design, and a builder's quote alone won't account for them.
One listed building in the area is on Historic England's Heritage at Risk register. That means a building in poor condition, where repair work may qualify for grant support and will certainly be scrutinised. It's no risk to the owner of an ordinary house down the road. For anyone thinking of buying that particular building, it means a lot of meetings with officials.
In practice, an unlisted post-war house outside any conservation area can usually use permitted development rights for modest extensions, provided it stays within the national limits, while a listed building needs consent for almost everything. Check whether the house is on the national heritage list first, because that one fact decides which of those two routes applies.
Your freedom to extend in Toddington is limited for a village of this size. The listed buildings and the clay mean that what you can do, and what it will cost, depends a great deal on which house you buy.
