Annexes in Redhill
An annexe is self-contained living accommodation on the same plot as a main house, complete with its own kitchen and bathroom facilities, built either as a new detached structure, a conversion of an existing outbuilding, or an extension with its own entrance.
In Redhill, that covers Earlswood, Salfords, South Park, Whitebushes, St John's, Three Arch Road. Redhill developed rapidly as a Victorian railway town and today has a mixed housing stock including Victorian terraces close to the centre, interwar suburbs, and later estate housing further out, with good rail links into London.

FAQs
Annexes in Redhill: FAQs
Do you provide annexes across all of Redhill?
Yes, we cover the RH1 postcode area in full, including Earlswood, Salfords, South Park, Whitebushes, St John's, Three Arch Road.
Do I need planning permission for an annexe?
Usually yes, because independent cooking, sleeping and washing facilities mean the structure is not treated as a simple outbuilding. Some annexes intended purely as ancillary accommodation for the main house can fall under permitted development, but this depends on size, position and local policy, which we check during feasibility.
Can an existing garage or outbuilding be converted into an annexe?
Yes, provided the structure is suitable and can be brought up to full Building Regulations standard for insulation, damp-proofing and services. We assess this as part of the feasibility stage alongside a new-build option.
Are Redhill's Victorian terraces suitable for loft conversions?
Many are, subject to roof pitch and head height, which we assess on survey. Rear dormers are a common solution to gain additional headroom on this house type.
