- Full internal finish or kitchen-ready shell
- Householder planning application
- Foundations, drainage and any manhole relocation
- Structural design for the corner and openings

The corner is where wraparounds succeed or fail. We usually use a single steel goalpost or a corner post hidden in a pier, and set the glazing so the new room reads as one space rather than two boxes.
Working in Darton
Across S75, we can visit, measure and advise. We also work in nearby Barnsley (3 miles), Rawmarsh (12 miles), Rotherham (13 miles), Adwick le Street (14 miles).
For homes towards West Yorkshire, Wakefield is around 7 miles away. Homes across Yorkshire and the Humber range from back-to-back and through terraces to large suburban semis, and extension options vary with them.
Planning rules that apply in Darton
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).
In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
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).

Questions people ask about wraparound extensions
Who do I contract with for a wraparound extension in Darton?
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.
Will my neighbours in Darton be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Do you cover all of Darton?
Yes. We cover Darton and the surrounding parts of South Yorkshire. Site visits are free and there is no obligation.
How much does a wraparound extension cost?
Our guide range is about £1,880 to £3,480 per m² including VAT. A 25 m² standard-spec wraparound typically lands around £54,000 to £68,500 in Darton before design and council fees.
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.
