Builders in East Grinstead

The town has a long history, and its High Street includes timber framed buildings that are far older than most homes in Sussex. Around the centre are Victorian and Edwardian houses, inter-war and post-war semis and more recent developments, many of which are now due for updating. The historic centre includes a conservation area and listed buildings, so check with Mid Sussex District Council before planning work to an older property.

Renovating an older house often uncovers work that was not in the original plan, from tired wiring to damp or failing plaster. It makes sense to commission a survey before you agree a price and to hold back a contingency for surprises. Our house renovation cost guide covers the full range of renovation work.

Outside conservation areas and other protected land, many houses can be extended under permitted development. The Planning Portal allows a single storey rear extension of up to four metres on a detached house or three metres on other houses, and a loft conversion adding up to 40 cubic metres on a terraced house or 50 cubic metres on others. These rights do not apply to flats or maisonettes, and they are restricted for listed buildings.

Parts of the countryside around the town lie within the High Weald area of outstanding natural beauty, which is Article 2(3) designated land with tighter limits. Where planning permission is needed, GOV.UK sets the householder fee for a single dwellinghouse at £548 from 1 April 2026. Read our extension planning permission guide for more on the process.
