Local detail

Surrey is the highest-volume KDR county outside London. Mole Valley (Dorking, Leatherhead), Waverley (Farnham, Haslemere, Cranleigh), Elmbridge (Esher, Cobham, Walton, Weybridge), and Tandridge (Oxted, Lingfield, Caterham) handle most of the activity.

Metropolitan Green Belt covers the central belt of the county; Surrey Hills AONB covers much of the west and south-east. Both require careful design and material specification but neither precludes replacement dwellings; the materially-larger NPPF Para 84(d) test is the controlling check.

Surrey authorities are mostly experienced with self-build CIL Form 7 procedure; submit it before any works including demolition. Premium tier (£/sqm) is the dominant build choice on Surrey plots given the established end-value comparables.
