Can I extend a house in Weybourne (Waverley)?

For anyone buying or renting in Weybourne (Waverley).

Yes, and with fewer heritage hoops than most of Farnham. There are no conservation areas. Only a small number of homes are listed. The clay underfoot is the bigger conversation. Here, the ground asks more questions than the council does.

Weybourne has 18 listed buildings: none at Grade I, one at Grade II* and 17 at Grade II. Listing covers the whole building, inside and out, so changing one needs listed building consent on top of any planning permission, and the fittings nobody photographs are protected along with the frontage. Eighteen out of a place this size means the odds are firmly against the house you're viewing being one of them. If it is, the particulars should say so, and the sale price should already have noticed.

There are also no conservation areas and no scheduled monuments within the area. That matters more than the listed count. A conservation area puts every street under tighter control over demolition, cladding, windows and roof changes, and Weybourne has none of that. The conservation paperwork lives in Farnham town, a short drive away and a different planning conversation.

The neighbours are not sitting still. Between April 2024 and June 2026, 2,487 planning applications were logged in and around the area, 1,044 of them in the last twelve months. That's the sound of loft ladders going in and side returns being eyed up. Nobody submits that many applications in a place where extending is a lost cause.

The catch is underground. The British Geological Survey places parts of Weybourne in shrink-swell class 3, the moderate band, covering about 32% of the area's postcodes. Clay soils in that class expand when wet and shrink when dry, which moves foundations over time. For an extension it means deeper footings, a structural engineer's view before the architect draws anything ambitious, and some thought about the tree nearest the new wall. It is a cost line, not a reason to walk away.

In practice, most Weybourne homes start from the standard position: many modest rear extensions, loft conversions and outbuildings can go ahead under permitted development rights without a full application, while anything larger, taller or closer to the boundary needs planning permission. Check whether the house has had those rights removed by an earlier permission or planning condition, and ask the council for a lawful development certificate before the builders arrive, not after the neighbour's complaint does. Listed homes play by a different rulebook entirely.

Freedom to extend is one of Weybourne's quieter strengths: little heritage control, no conservation areas, and plenty of neighbours proving it can be done. Budget for the clay and the engineer, and the rest is a normal planning conversation.
