Wraparound extension in Grays
An L-shaped extension that fills the side return and runs across the back. We design, get the approvals for and build wraparound extensions in Grays and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Grays (RM16, RM17 and RM20) as part of our Essex work. Wraparound projects around Grays often involve two neighbours, so we start the party wall conversations early.

Do you need planning permission for a wraparound extension in Grays?
Whether your wraparound extension in Grays needs a planning application depends on its size, your house and any local restrictions.
In England the side part of a side return or wraparound must meet the side-extension rules (one storey, under 4 metres high, no more than half the width of the original house), and those rights do not apply on designated land. Because a wraparound combines a side and a rear extension, many need householder planning permission.
Because rear extensions often sit on or near the boundary, the Party Wall etc. Act 1996 usually applies in England. Notices go out one or two months before work depending on the type of work, and a surveyor's award is only needed if a neighbour does not consent.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Grays like to extend?
Post-war semis and newer estates are typical of Grays, and many have room for a full-width extension. Shrinkable clay is common in the East of England, so foundations near trees and hedges are designed to NHBC-style depth guidance.

Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
