FAQs
Structural Alterations in Dorking: FAQs
Do you provide structural alterations across all of Dorking?
Yes, we cover the RH4 and RH5 postcode areas in full, including Westcott, Milton Heath, Pixham, Ranmore, North Holmwood, Betchworth.
Do I need planning permission to remove an internal wall?
Usually no — removing an internal load-bearing wall is normally a Building Regulations matter rather than a planning one, provided the property isn't listed and the work doesn't affect the external appearance. We confirm the position for your property at survey.
How do I know if a wall is load-bearing?
Load-bearing walls typically run perpendicular to floor or roof joists, sit above a wall or support on the floor below, or align with the roof structure — but this isn't reliable to judge by eye, so we assess it on-site and confirm with a structural engineer before any work starts.
Can barns near Dorking be converted to residential use?
It depends on the specific planning history and policy for the building, including whether Class Q permitted development rights apply. This is assessed individually for each building.
