Extensions in Horsforth
The semis and family houses in Horsforth usually have a rear garden with room to build and a kitchen that was never big enough. A single storey rear extension, in brick to match or rendered where the house is, takes the kitchen and the old dining room into one open room with doors onto the garden. We match the brick bond and mortar colour, pick up the eaves and the roofline, and draw the whole thing before we price it.

Permission, permitted development and the Leeds portal.
Many single storey rear extensions in Horsforth fall under permitted development: up to 4 metres on a detached house and 3 metres on a semi or terrace, with a height limit at the eaves. Larger extensions, side extensions on some houses, two storey work and anything in a conservation area need an application to Leeds City Council. If yours has already been approved, the decision and the drawings are published on Leeds Public Access, and that is all we need to price it.
Extensions: questions people in Horsforth ask
Do I need planning permission for an extension?
Many single storey rear extensions fall under permitted development, up to 4 metres on a detached house and 3 metres on a semi or terrace. Larger ones, side extensions on some houses and anything in a conservation area usually need an application. We will tell you which applies to yours before anything is drawn.
How much does an extension cost in West Yorkshire?
It depends on the size, the roof, the openings and what goes inside, so we do not publish a price list. Draw the extension you want on this site and you get a guide range straight away, then send us your plans and the fixed price comes from the drawing.
How long will we be without a kitchen?
We sequence the work so the old kitchen stays in use for as long as possible, usually until the new shell is watertight. Most families are without a kitchen for two to three weeks in the middle of the job.
