House extension builders in Halifax

We work in Halifax a lot. Three of the bathrooms and one of the extensions in our projects are Halifax homes.
What to know before you start
Planning in Halifax
Many single-storey rear extensions fall under permitted development. Anything bigger, or in a conservation area, needs planning permission from Calderdale Council. We prepare the drawings and handle the application.
Matching your house
Victorian stone terraces on steep streets, plus stone semis and detached homes on the edges of town. 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 Halifax
We also work across Sowerby Bridge, Elland, Brighouse, Hebden Bridge and the rest of the area. Same team, same standards, wherever the job is.

Extensions in Halifax: common questions
Do I need planning permission for an extension in Halifax?
Often not. Many single-storey rear extensions fall under permitted development. If yours does need permission, the application goes to Calderdale Council, and we prepare and submit it for you.
How much does an extension in Halifax 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.
