Will the council need to approve it?
In England a wraparound extension is assessed as both a side and a rear extension, and the combination usually falls outside permitted development, so most need a householder planning application (£548 from 1 April 2026).
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Applications are decided by the local planning authority (your district, borough or unitary council).
What is included
- Survey, design and 3D layout options
- Party wall notice support (England and Wales)
- Structural design for the corner and openings
- Householder planning application
Covering Cromer
Site visits are available across Cromer (NR27). We also work in nearby North Walsham (8 miles), Norwich (21 miles), Dereham (23 miles), Wymondham (26 miles).
Lowestoft, in Suffolk, is roughly 36 miles from Cromer and also on our list. The East of England mixes market-town terraces, inter-war semis and modern estates. Clay soils are common in parts of the region, which can affect foundation design.

Questions people ask about wraparound extensions
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Cromer, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Cromer?
Yes. We cover Cromer and the surrounding parts of Norfolk. Site visits are free and there is no obligation.
Who do I contract with for a wraparound extension in Cromer?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Do wraparound extensions need planning permission?
Usually, yes. In England the side element counts as a side extension and the rear element as a rear extension, and the combination normally falls outside permitted development. A householder application costs £548 in England from 1 April 2026.
Is a wraparound better than a side return alone?
It adds far more space, but costs more and needs planning permission more often. Our comparison guide sets the two side by side.
