What Is a Single Storey Extension?
A single storey extension is an addition to the ground floor of your home — typically built to the rear or side — that creates new, purpose-built living space. It’s the most popular and cost-effective way to add square footage to a property, and in most cases can be built under Permitted Development rights without full planning permission.
Common uses include:
- Kitchen extensions — open up to a large, light-filled kitchen diner or family room
- Rear extensions — bring the outside in with bi-fold doors and glazed roofs
- Side extensions — use side access or garage space to add utility rooms, studies, or extended hallways
- Wrap-around extensions — combine rear and side for maximum space gain
- Garden rooms and orangeries — a premium alternative to a conservatory, built to the same standard as the main house

Planning Permission for Single Storey Extensions in Warwickshire
Most single storey extensions in Warwickshire can be built under Permitted Development rights — meaning no planning application is required. The key limits are:
- The extension must not extend beyond the rear of the original house by more than 4 metres (detached) or 3 metres (semi-detached or terraced)
- Under the Prior Approval (Neighbour Consultation) scheme, rear extensions up to 8 metres (detached) or 6 metres (other) can be approved after a 42-day consultation period
- The extension must not exceed the height of the existing eaves or ridge
- Side extensions are limited to half the width of the original house
Properties in conservation areas, listed buildings, and some designated zones may have additional restrictions. We’ll advise you on this during your free consultation.

Why single storey extensions are popular in Warwickshire homes
Warwickshire has one of the strongest mixes of property types in the Midlands — Victorian terraces in Nuneaton and Leamington, post-war semis across Coventry, modern detached estates in Rugby, period stone cottages in the Stratford villages. Almost all of these benefit hugely from a single storey extension because:
- Most fall under permitted development — meaning no planning headache for a properly-scoped project.
- Cost-efficient per m² — at £1,800–£2,800/m² in 2026, single storey is the most cost-effective way to add real living space.
- Disruption is contained — you can usually live in the house through the build, unlike a double storey or full renovation.
- They unlock the back of the house — most Warwickshire homes have a generous garden but a small kitchen and dated rear access.

Do you handle planning and building regs?
Yes — every project includes design, planning where needed, structural engineering, building regulations submission and sign-off as part of one fixed price.
Can I extend if my house is in a conservation area?
Yes, but you will need full planning permission and the design will need to respect the area character. We have delivered conservation-area extensions in Warwickshire before.
