FAQs
Retaining Walls in Dorking: FAQs
Do you provide retaining walls 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 for a retaining wall?
Most garden retaining walls fall under permitted development, but taller walls, those near a public highway, or in a conservation area, may need planning permission or Building Regulations consideration — we confirm the position for your specific site during survey.
Does a retaining wall need its own foundation and drainage?
Yes. A retaining wall needs a foundation sized for the height and loading involved, plus drainage behind the wall (such as land drain and weep holes) to relieve water pressure — without this, walls are prone to bulging or failing over time.
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.
