Single Storey Rear Extensions Built for Arnold Homes
Arnold has a great mix of housing – 1930s semis, post-war family homes and newer estates towards Redhill and Woodthorpe. Most of these properties have decent rear gardens, which makes a single storey rear extension a natural fit. You keep your garden’s best space while adding a bright, open room where your family actually spends its time.
The most common project we build in Arnold is a 3m to 6m rear extension that opens up the old kitchen and dining room into one large kitchen-diner, often with bifold or sliding doors onto the garden and a roof lantern for extra daylight. Because many Arnold semis have similar layouts, we can usually show you examples of what has worked well on homes just like yours.
Every project starts with a free site survey. We measure up, talk through what you want, check whether your plans fall under permitted development, and give you a clear fixed price. If planning permission is needed, we prepare and submit the application to Gedling Borough Council on your behalf.
Best suited to: growing families who need a bigger kitchen or living space, homeowners who want to add value without moving, and anyone with an underused rear garden or dated lean-to that could work much harder.
Quick Facts
Typical size: 3m-6m deep. Build time: 10-14 weeks. Many Arnold rear extensions qualify as permitted development, so no full planning application is needed.

- More usable living space – turn a cramped kitchen into a large open plan kitchen-diner where the whole family can gather.
- Added value – a well-built rear extension typically adds 10-15% to the value of an Arnold home, often more than the build cost.
- Cheaper than moving – avoid stamp duty, agent fees and the stress of leaving a street and schools you already like.
- Better garden connection – bifold or sliding doors bring the garden into daily life instead of hiding it behind a small back door.
- More natural light – roof lanterns and skylights flood the middle of the house with daylight, not just the new room.
- Often no planning needed – many single storey rear extensions in Arnold fall under permitted development rights.

Planning Rules for Rear Extensions in Arnold
📋 What Arnold homeowners should know
Under permitted development, a single storey rear extension can usually extend up to 4m from the rear wall of a detached house, or 3m for a semi or terrace, with a maximum height of 4m. Larger schemes up to 8m (detached) or 6m (other houses) may be possible through the prior approval process. Anything beyond that, or on flats and some newer estates where rights have been removed, needs full planning permission from Gedling Borough Council. We check all of this for you at the survey stage and handle any applications – our planning success rate is 100%.
