C&J Construction & Roofing LTD designs and builds house extensions across Wakefield, Barnsley, Pontefract, Leeds, Bradford, Halifax and the wider West Yorkshire area. We take on the whole job, from footings and drainage through to the roof, the windows, the plastering and the final decoration, with one team accountable for the lot.

An extension is the largest single investment most households make in their home, and the thing that goes wrong most often is coordination. Five separate trades, five separate schedules, and nobody holding the programme together. We build the whole thing ourselves, which is why our customers keep mentioning in reviews that we turn up when we say we will.

What a full extension from C&J includes:

  • Site setting out, footings dug and poured to building control approval
  • Drainage runs, inspection chambers and connections
  • Brickwork and blockwork built to match the existing property
  • Structural steels installed and encased where openings are formed
  • Complete roof structure, covering, lead work, fascias and guttering
  • Windows, bifold doors and roof lights fitted
  • First and second fix carpentry, electrics and plumbing coordinated
  • Plastering, screed and floor finishes
  • Building control liaison and sign off at every stage

We work from your drawings, or we can point you to architects and structural engineers we work with regularly if you are still at the idea stage.

Common questions

Questions about house extensions

If your question is not answered here, call 07927 976489 and ask.

How long does a house extension take to build?

A single storey rear extension is typically twelve to sixteen weeks from breaking ground to handover. Two storey extensions usually run sixteen to twenty four weeks. Weather, structural steel lead times and building control inspections all affect it, and we give you a written programme with your quote.

Do I need planning permission for an extension?

Many single storey rear extensions fall under permitted development, but the limits on depth, height and boundary position are strict and they are different for terraced, semi detached and detached homes. Conservation areas and listed buildings are different again. We will tell you honestly at the quote stage which route yours needs.

Can you manage the whole project including other trades?

Yes. We take the job end to end, including groundworks, brickwork, roofing, carpentry and coordinating electrics and plumbing. You deal with one contractor and one programme rather than chasing five different trades yourself.

Customer feedback

What our customers say

5 out of 5 from 5 reviews left on Facebook by customers across West Yorkshire.

  • We recently had our roof replaced by Connor and his team, and I honestly could not recommend them highly enough. From the very beginning, Connor was friendly and professional. Communication was excellent throughout the whole job. Any questions were answered quickly, and we were always kept informed about what was happening. The work was completed much quicker than we expected without compromising on quality, and the finished roof looks fantastic. The team worked hard, were respectful of our property, and left everything clean and tidy when they finished. Thank you to Connor and everyone involved for doing such a great job.

  • The work done was excellent. Turned up on time, worked all day, left the job tidy every day and the final finish was more than we expected. First class workers.

  • Connor and his team arrived on time every day and worked tirelessly to get the job done. They were well mannered, they did everything I asked and answered all of my questions. My roof looks great and I would highly recommend them to anyone thinking about using them. Thank you C&J.
