L Shaped Extension Carlton
An L shaped extension wraps around the rear and side of your home at the same time, giving you far more space than a single extension on its own. Across Carlton, Gedling and Porchester, we design and build L shaped extensions that turn cramped kitchens and unused side returns into big, bright open-plan living areas.
From the first survey to the final coat of paint, one local team manages the whole project – design, planning, structural work and finishing.
- Free site survey and design advice in Carlton
- Full planning and building regulations handled
- Fixed written quotes with no hidden extras
L Shaped Extensions for Carlton Homes
Carlton has a great mix of housing – Victorian terraces near Carlton Hill, 1930s semis around Cavendish Road and post-war homes towards Gedling. Many of these properties share the same problem: a narrow kitchen at the back and a dead strip of land down the side. An L shaped extension solves both at once. By building across the rear and along the side return, the new space forms an L that flows around the original house.
The result is usually a large open-plan kitchen, dining and family room, often with a utility, downstairs WC or home office worked into the layout. Because the extension uses land you already own but rarely use, it adds a lot of floor area without eating too far into the garden.
We are a local firm, so we know Gedling Borough Council’s planning approach, the typical soil conditions in the area and the party wall issues that come up on Carlton’s terraced and semi-detached streets. Every project starts with a free survey at your home, where we measure up, talk through your ideas and give you honest advice on what will work and what it will cost.
An L shaped extension is a type of wrap around extension, so if you want to compare options you can read more on our main wrap around extensions page, or see everything we build locally on our home extensions in Carlton hub.
Best For
Semis and terraces in Carlton with a side return or side path, and families who want one large open-plan kitchen-diner rather than several small rooms.
Typical Timescale
Most single storey L shaped extensions in Carlton take 12 to 16 weeks on site, plus 8 to 12 weeks beforehand for design and approvals.
Benefits of an L Shaped Extension in Carlton
- Maximum floor space – you extend across the rear and side in one build, often gaining 25 to 40 square metres of new living area.
- Better value per metre – one build combining two extensions costs less than doing a rear and side extension separately, with one set of foundations, scaffolding and trades.
- Uses wasted side space – the narrow side return found on many Carlton semis and terraces becomes useful kitchen or utility space instead of a bin store.
- Open-plan living – the L shape suits a big kitchen-diner with bifold or sliding doors onto the garden, plus a separate zone for a snug or office.
- Adds real value – well-built extensions in the NG4 area typically add more to a home’s value than they cost, and they beat the price of moving.
- Natural light – roof lights over the side return and glazing across the rear keep the middle of the house bright all day.

Planning Permission in Carlton
What you need to know
Because an L shaped extension wraps around two sides of the house, it usually falls outside permitted development rights, so most projects in Carlton need a full planning application to Gedling Borough Council. Decisions normally take about 8 weeks. Key points the council looks at include the impact on neighbours’ light and privacy, the size of the extension compared to the original house, and matching materials. Terraced and semi-detached homes will also need party wall agreements with adjoining neighbours. We prepare and manage the whole application for you, and we have a 100% planning success rate on schemes we have designed locally.

What Carlton Homeowners Say
“Our L shaped extension has completely changed our house on Carlton Hill. The old kitchen and side alley are now one huge kitchen-diner. Planning with Gedling council was handled for us and the build finished a week early.”
“We got three quotes for a wrap around on our 1930s semi in Carlton and these were the most honest by far. Fixed price, tidy site, and the roof lights over the old side return make the whole ground floor so bright.”
“From survey to sign-off it took just over five months. The team sorted the party wall notices with both neighbours and kept us updated every week. Our Carlton terrace now has the kitchen we always wanted.”
