L Shaped Extension Arnold
An L shaped extension wraps around the rear and side of your home, giving Arnold homeowners far more space than a standard rear extension. It is the smart way to create a large open-plan kitchen, dining and living area in one build.
We design and build L shaped extensions across Arnold, from the semis around Front Street to the larger plots near Arnold Lane and Gedling Country Park. Free survey, honest fixed pricing, and full planning support.

Why Arnold Homes Suit an L Shaped Build
An L shaped extension, sometimes called a wrap around, combines a rear extension and a side extension into one L shaped footprint. In Arnold, many semi-detached and detached homes have a side return or driveway strip that sits unused. Wrapping the build around that corner turns dead space into real living space.
The result is usually a wide, open-plan kitchen and family room with far more glazing and light than a straight rear extension can offer. Because both parts are built at the same time, you also save money compared with doing two separate projects years apart.
We know Arnold’s housing stock well, from 1930s semis off Mansfield Road to newer homes near Killisick and Redhill. That local knowledge matters when it comes to party walls, drains and Gedling Borough Council’s planning expectations. Every project starts with a free survey so you get advice based on your actual plot, not guesswork.
This page covers what an L shaped extension involves in Arnold, what it is likely to cost in 2026, and how planning works. If you want the broader picture, see our main wrap around extensions page or the Arnold extensions hub.
Best For
Arnold semis and detached homes with a side return or wide plot, families wanting a large open-plan kitchen-diner, and anyone who wants maximum ground-floor space in one build.
Typical Timeline
Design and planning: 8-12 weeks. Build: 12-18 weeks depending on size and finish. We give you a written programme before work starts.
What an L Shaped Extension Gives You
- Maximum floor area – by using both the rear and side of the house, you gain far more space than a single straight extension.
- True open-plan living – the L shape creates a wide, sociable kitchen, dining and family zone in one connected room.
- Better light – two external walls mean more options for bifold doors, roof lights and corner glazing.
- One build, one disruption – combining rear and side works into a single project is cheaper and less stressful than two separate builds.
- Strong added value – a well-built L shaped extension typically adds significant resale value to Arnold family homes.
- Flexible layouts – room for a utility, snug or home office alongside the main open-plan space.

Do You Need Planning Permission?
📋 Because an L shaped extension wraps around two elevations, it usually falls outside permitted development rights and needs a full planning application to Gedling Borough Council. Key points for Arnold homes:
- Side elements normally must be single storey and no wider than half the width of the original house to have any chance under permitted development, which most L shapes exceed.
- Corner plots and homes near Arnold’s conservation-sensitive streets may face tighter design conditions.
- Party wall agreements are often needed on semi-detached homes.
- Building Regulations approval is required in all cases.
We prepare and manage the whole application for you, and our planning success rate across Gedling borough is 100%.

What Arnold Homeowners Say
“Our L shaped extension has completely changed how we use the house. The side return was wasted space before – now it is part of a huge kitchen-diner. The team handled Gedling planning without any fuss.”
“Fixed price quote and they stuck to it, even when the drains needed moving. Finished our wrap around in Arnold on schedule and the bifolds look superb. Would recommend to anyone locally.”
“From the first survey to handover everything was clearly explained. The L shape gave us a kitchen, dining space and a small office in one build. Neighbours in Arnold keep asking who did it.”
L Shaped Extension Arnold – Your Questions

Most projects in Arnold fall between 60,000 and 150,000 pounds in 2026, depending on size, glazing and finish. A medium 30-40m² build with bifolds and a mid-range kitchen typically lands between 80,000 and 110,000 pounds. Your free survey leads to a fixed written quote.

Many do. If your home has a side return, alley or driveway strip beside the kitchen, that space can usually be built over. Semis will normally need a party wall agreement with the neighbour, which we arrange as standard.
Yes, most Arnold clients live in their home throughout. We keep the existing kitchen usable for as long as possible, seal off the work area, and agree a temporary kitchen setup before the final knock-through.
