Wraparound extension in Grimsby
For homes in Grimsby, a wraparound extension is often the simplest way to gain space without moving. An L-shaped extension that fills the side return and runs across the back. We take it from survey to completion certificate.
Grimsby sits in Lincolnshire, with postcode districts including DN31, DN32 and DN34. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Lincolnshire where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Grimsby?
Planning for a wraparound extension in Grimsby follows the English householder rules.
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 Grimsby like to extend?
Red-brick terraces and semis are typical of Grimsby. Coal-mining legacy areas in parts of the East Midlands can need a Coal Authority check before foundations are designed.

Wraparound extension questions in Grimsby
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.

Usually 14 to 20 weeks on site, longer than a plain rear extension because of the steelwork.

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.
