Wraparound extension in Castleford
We plan and build wraparound extensions for homeowners in Castleford. An L-shaped extension that fills the side return and runs across the back. Start with a free site visit, then a written price once the design is agreed.
We cover Castleford (WF6, WF8 and WF10) as part of our West Yorkshire work. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in West Yorkshire where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Castleford?
The planning route for a wraparound extension in Castleford is set by England's householder rules and your council.
Side return infills and the side leg of a wraparound are treated as side extensions in England: single-storey, no more than 4 metres high and no wider than half the original house. They are not permitted development in conservation areas, National Parks or National Landscapes, and a joined wraparound often needs a planning application because the side and rear rules apply together.
The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Castleford like to extend?
Castleford has through terraces and some back-to-backs as well as later semis; back-to-backs have little or no rear space, so we look at side or loft options there.

FAQ
Wraparound extension questions in Castleford
Is the site visit in Castleford free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
How long does a wraparound take?
Usually 14 to 20 weeks on site, longer than a plain rear extension because of the steelwork.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Do I need a party wall agreement?
In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.
Do you handle building control in Castleford?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
