Sometimes you don't need to move — you just need more room. A single storey extension Leeds homeowners choose is the smartest way to gain a bigger kitchen, a dining space, a home office or a family room without the cost and upheaval of relocating. With 20 years' experience, CLM Projects builds rear and side single-storey extensions that flow naturally from your existing home and stand the test of time. One experienced team takes you from drawings and planning support through groundworks, brickwork, roofing, glazing and finish, to a watertight handover — built properly throughout. We coordinate Building Regulations, keep the site clean and respectful, and work to a clear programme. Fully insured and proudly Leeds-based, we're built on trust and built to last. If you're weighing up how much space and value you could add, book a free, no-obligation quote and we'll talk it through.

FAQs

Single Storey — Your Questions

Do I need planning permission for a single storey extension in Leeds?

Many single-storey rear extensions fall within permitted development rights, subject to size, height and boundary limits and always to conditions. We recommend confirming your case with Leeds City Council, and we'll prepare the drawings and manage any application needed.

How much space can a single storey extension add?

It depends on your plot and permitted development limits, but a well-planned rear or side extension can add a substantial room such as a large kitchen-diner or family space. We'll assess what's realistic on your property during your free quote.

How long does a single storey extension take?

Typically around 8 to 12 weeks on site depending on size, groundworks and finish. You'll receive a clear programme with your quote so the timeline is set out upfront.

What about the party wall — do I need an agreement with my neighbour?

If your extension involves work on or near a shared boundary or wall, the Party Wall Act may apply and require notice to your neighbour. We'll flag this early and advise you on the steps so nothing holds up the build.

Will you manage Building Regulations?

Yes. We coordinate Building Regulations and the required inspections throughout, and provide planning support and drawings, so it's all handled by one experienced team.
