What to know before you start
Planning in Doncaster
Many single-storey rear extensions fall under permitted development. Anything bigger, or in a conservation area, needs planning permission from Doncaster Council. We prepare the drawings and handle the application.
Matching your house
Brick semis and terraces, former pit-village rows, and newer estates. 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 Doncaster
We also work across Bawtry, Thorne, Mexborough, Armthorpe and the rest of the area. Same team, same standards, wherever the job is.
Extensions in Doncaster: common questions
Do I need planning permission for an extension in Doncaster?
Often not. Many single-storey rear extensions fall under permitted development. If yours does need permission, the application goes to Doncaster Council, and we prepare and submit it for you.
How much does an extension in Doncaster 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.
