Yes, and with less paperwork than most buyers brace for. There is no conservation area anywhere in Marston Moretaine. The listed buildings fit on one hand and a bit. The neighbours are applying for planning permission at a steady clip. The thing with the strongest opinions about your extension is the clay underneath it.
Historic England lists nine buildings in the area: two at Grade I, one at Grade II* and six at Grade II. Listing covers the whole building, inside and out, so changing one of them needs listed building consent on top of any planning permission, and that includes alterations that would be routine on any other house. Nine is a small enough number that most buyers will never own one, and the ones who do will know about it from the first viewing.
There is one scheduled monument in the area, the strictest tier of protection there is. It matters mainly to anyone with land right next to it, and for an ordinary house on an ordinary street it is a footnote.
The people already living here are not shy about building. The area logged 1,168 planning applications between April 2024 and June 2026, 541 of them in the last twelve months. A village that files that many forms has clearly decided the house it bought was a first draft.
The ground needs more thought than the heritage. The British Geological Survey puts every postcode in the area at class 3 for shrink-swell, the clay that swells when wet and shrinks when dry. For an extension that means deeper foundations than a builder might quote by default, plus a structural engineer's view on how close any trees are. None of that stops an extension, though it does change the cost, and the clay will not wait for a planning officer to tell it what to do.
One listed building in the area is on Historic England's Heritage at Risk register, meaning it is in poor condition and in need of repair. Work on it is likely to attract grant support and close scrutiny in roughly equal measure, and it is a matter for its owner. For the buyer of a house down the road, it changes nothing.
In practice, with no conservation area, most houses here keep their full permitted development rights, so a modest rear extension, a loft conversion or an outbuilding can often go ahead without a full application, subject to the national size limits. Anything bigger goes to Central Bedfordshire Council as an ordinary planning application. Ask the seller for the original planning permission and any later approvals, because newer estates sometimes come with conditions that remove permitted development rights, and those only show up in the paperwork.
The freedom to change a house is one of Marston Moretaine's real strengths: the planning rules mostly leave you alone, and the only firm limit comes from the clay under the foundations.
