House extension builders in Sheffield
We build single and two-storey, side-return and wraparound extensions in Sheffield, with one team from the drawings to the last coat of paint.
One of our two-storey stone extensions is in Sheffield, so we know our way around South Yorkshire. We're happy to head down the M1 for the right project.
What to know before you start
Planning in Sheffield
Many single-storey rear extensions fall under permitted development. Anything bigger, or in a conservation area, needs planning permission from Sheffield City Council. We prepare the drawings and handle the application.
Matching your house
Red-brick terraces, stone houses on the western side of the city, and plenty of steep plots. We match the stone, brick or render so the extension looks like it was always there.
Building regulations
Every extension needs building regulations approval, even without planning. We book the inspections at each stage and hand you the completion certificate.
Around Sheffield
We also work across Rotherham, Stocksbridge, Hillsborough, Dronfield and the rest of the area. Same team, same standards, wherever the job is.

Extensions in Sheffield: common questions
Do I need planning permission for an extension in Sheffield?
Often not. Many single-storey rear extensions fall under permitted development. If yours does need permission, the application goes to Sheffield City Council, and we prepare and submit it for you.
How much does an extension in Sheffield cost?
We can't give a fair price without seeing the job. Size, number of storeys, ground conditions, glazing and the kitchen or bathroom fit-out all change the price. We visit for free, measure up and send an itemised quote, so you can see exactly where the money goes.
