House extension builders in York
We build single and two-storey, side-return and wraparound extensions in York, with one team from the drawings to the last coat of paint.
York's older homes need a careful hand. We build extensions and refit kitchens and bathrooms in and around the city, and we check the conservation rules before we draw anything.
What to know before you start
Planning in York
Many single-storey rear extensions fall under permitted development. Anything bigger, or in a conservation area, needs planning permission from City of York Council. We prepare the drawings and handle the application.
Matching your house
Victorian terraces and older properties, with many homes inside conservation areas. 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 York
We also work across Haxby, Acomb, Tadcaster, Selby and the rest of the area. Same team, same standards, wherever the job is.
Extensions in York: common questions
Do I need planning permission for an extension in York?
Often not. Many single-storey rear extensions fall under permitted development. If yours does need permission, the application goes to City of York Council, and we prepare and submit it for you.
How much does an extension in York 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.
