FAQs
Garage Conversions in Dorking: FAQs
Do you provide garage conversions 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 convert my garage?
In most cases no, provided the external appearance and the building's footprint stay the same — this typically falls under permitted development. If you're altering the external walls, adding windows to a street-facing elevation, or the property has restricted permitted development rights, a planning application may be needed, which we confirm at survey.
Will my garage conversion need Building Regulations approval?
Yes. Bringing a garage into habitable use always requires Building Regulations approval, covering the floor, insulation, damp-proofing, ventilation, electrics and, where relevant, fire safety between the conversion and the rest of the house.
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.
