Extensions in and around Deal
We cover Deal and the postcode districts CT14. The same team covers Dover (8 miles), Ramsgate (8 miles), Broadstairs (9 miles), Margate (11 miles), all within easy reach.
Just over the Essex border, Southend-on-Sea is about 37 miles away. In the South East, plenty of houses have already been extended once, which makes checking the remaining permitted development allowance an important early step.
Included in a typical project
- Householder planning application
- Party wall notice support (England and Wales)
- Roof with glazing along the side return
- Full internal finish or kitchen-ready shell
- Survey, design and 3D layout options
Planning and approvals in Deal
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).
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).
From first visit to completion
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.

Common questions in Deal
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Deal, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Who do I contract with for a wraparound extension in Deal?
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 I need building regulations approval in Deal?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
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.
Will I need to move a drain?
Often. Side returns frequently contain a manhole or a shared drain. Building near or over a public sewer needs the water company’s consent in England and Wales, which we arrange.
