Single Storey Rear Extension Carlton
A single storey rear extension is the most popular way for Carlton homeowners to gain a bigger kitchen, a dining space or an open plan family room. We design and build rear extensions across Carlton, Carlton Hill, Gedling and Netherfield, handling everything from drawings to decoration.
Many Carlton homes are 1930s semis and post-war properties with decent rear gardens, which makes them ideal for this type of project. We know the local housing stock and the Gedling Borough Council planning process inside out.

Rear Extensions Built for Carlton Homes
Carlton has a strong mix of 1930s bay-fronted semis, Victorian terraces near Carlton Hill and later post-war houses towards Gedling. Most of these homes share the same problem: a small, closed-off kitchen at the back that no longer suits family life. A single storey rear extension solves this by pushing the back wall out into the garden, creating one bright, open space for cooking, eating and relaxing.
We manage the whole project from our first visit to final handover. That includes measured surveys, architectural drawings, structural calculations, planning or permitted development checks with Gedling Borough Council, building regulations sign-off and the build itself. You deal with one team and one point of contact throughout.
Typical Carlton projects include kitchen-diner extensions of 3m to 4m depth, garden rooms with bifold doors, and extensions with roof lanterns or large rooflights to bring light deep into the plan. Because many Carlton semis have generous gardens, there is usually plenty of scope without losing your outdoor space.
Who Is It Best For?
This project suits families who want an open plan kitchen-diner, homeowners who want to add value before selling, and anyone whose home layout feels cramped at the back. If your Carlton house has at least 3m of usable garden depth behind it, a single storey rear extension is almost always worth exploring.
📋 Quick Facts
Typical build time: 10-14 weeks. Most Carlton rear extensions up to 4m deep fall under permitted development. Full project management included as standard.

Benefits of a Single Storey Rear Extension in Carlton
Practical reasons Carlton homeowners choose to extend rather than move.
- More space where it matters – open up a cramped kitchen into a full-width kitchen-diner with garden views.
- Adds real value – a well-built rear extension typically adds 10-15% to the value of a Carlton semi.
- Cheaper than moving – avoid stamp duty, agent fees and moving costs while staying near local schools and Carlton Square.
- Often no planning needed – many rear extensions fall under permitted development, saving time and fees.
- Better light and flow – bifold doors, rooflights and lanterns transform dark north-facing rooms.
- Improved energy performance – new insulated walls, floor and roof built to current building regulations.

Do You Need Planning Permission in Carlton?
Permitted Development Basics
Most single storey rear extensions in Carlton do not need full planning permission. Under permitted development you can usually extend up to 4m from the rear wall of a detached house, or 3m from a semi or terrace, with a maximum height of 4m. Larger schemes up to 6m (semi) or 8m (detached) may be possible through the prior approval route.
Carlton falls under Gedling Borough Council. Flats, maisonettes and homes with previous extensions have different rules, and some streets have restrictions. We check your property’s exact position during the free survey and handle any application needed, and we recommend a Lawful Development Certificate even where permission is not required.

What Carlton Homeowners Say
“We had a 4m rear extension added to our semi in Carlton and the whole process was smoother than we expected. They sorted the drawings and building control, kept the site tidy, and finished a week early. The kitchen-diner has completely changed how we use the house.”
“Really professional from the first survey. They explained the permitted development rules for our street off Cavendish Road and got the certificate sorted so there were no surprises. The bifolds and lantern make the room feel twice the size.”
“Great communication throughout and the quote we signed was the price we paid. The team were polite with our neighbours, which matters on a terraced street in Carlton. We would recommend them to anyone thinking of extending.”
