What is a wraparound extension?
A wraparound extension combines a side return and a rear extension into one L-shaped addition. It gives the largest possible ground floor, often creating an open-plan kitchen, dining and living space across the whole width of the house.
How much does a wraparound extension cost in Ipswich?
In Ipswich, a wraparound extension typically costs £2,350–£3,400 per m² of floor area, including VAT at 20% (standard rate). For a typical 28 m² project that is roughly £66,000–£95,000. Building costs in the East of England run about 6% above the UK average, and the figures for Ipswich are adjusted to reflect that. Design, structural calculations and council fees are extra.

Do you need planning permission for a wraparound extension in Ipswich?
Approvals for a wraparound extension in Ipswich follow the rules for England. In England a wraparound extension combines side and rear elements, which normally takes it outside permitted development, so a householder planning application is made.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.

Questions about wraparound extensions in Ipswich
What about the old back addition?
The side wall of the back addition is usually removed and replaced with a steel beam, so the old kitchen joins the new space.
Who approves a wraparound extension in Ipswich?
Planning matters in Ipswich go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.
Is a wraparound worth it?
It gives the biggest ground-floor space without going upwards. Whether it adds value depends on your street and house, so we suggest checking local sale prices before committing.
