For most houses in Churchdown, yes, and with less fuss than almost anywhere with a church this old nearby. Only a handful of buildings are listed. There is no conservation area. The neighbours are building all the time. Unless you buy one of the rare listed buildings, the usual planning rules are about all that stands between you and the extension.
Historic England lists 16 buildings in Churchdown: one at Grade I, one at Grade II* and 14 at Grade II. Listing covers the whole building, inside and out, so changing one needs listed building consent, and alterations that suit a modern semi rarely suit a listed building. The local planning authority's check covers Churchdown with no conservation area and no scheduled monument. Sixteen buildings in a village this size means most buyers will never own one. The few who do will know about it long before they pick a kitchen.
Tewkesbury Borough Council's planning records show 491 applications in Churchdown between April 2024 and June 2026, and 211 in the most recent twelve months. That is a village altering its homes as a matter of routine. Owners here rarely sell, so they build, and the planning list is where that shows.
In practice, a house that is neither listed nor in a conservation area falls under the ordinary rules for householders. Plenty of modest rear extensions and loft conversions can go ahead under permitted development, within limits on size, height and position. Anything bigger, or anything facing the street, goes to the council for planning permission in the normal way. The one thing to find out is whether permitted development rights were taken away when the estate was built. Councils sometimes do that by condition on newer developments. Tewkesbury Borough Council can tell you from the property's planning history, and it is a short email that can save a long argument.
Freedom to extend is one of Churchdown's real strengths. The heritage list is short, there is no conservation area, and outside those sixteen buildings you need only ordinary permission.
