Rear Extensions Built for Arnold Homes
A rear extension is one of the most popular ways to add space to a home in Arnold, and for good reason. Many properties here have generous back gardens but tight, dated rooms at the ground floor. Extending into that garden space lets you open up the back of the house, bring in more natural light, and create the kind of open-plan kitchen and dining area that modern family life needs.
We build single-storey rear extensions across the whole of Arnold, from terraced homes near Arnot Hill Park to detached properties on the edge of Redhill. Each project starts with a proper look at your existing layout, your garden, and how you actually want to use the space. From there we handle the design, the drawings, building regulations, and the full build.
Because we are local, we understand the ground conditions, the typical brick and roof styles around Arnold, and how to match new work to your existing home so it looks like it was always there.
Why a Rear Extension?
It uses garden space you already own, rarely affects your street view, and often falls under permitted development. That usually means less planning hassle and a quicker start on site.
Local Coverage
We cover all of Arnold and the wider NG5 area, including Daybrook, Redhill and Woodthorpe. Free surveys, no pressure.
Benefits for Arnold Homes
- More usable ground-floor space – turn a cramped galley kitchen into an open-plan kitchen-diner that suits family living in Arnold’s older homes.
- Better natural light – large bi-fold or sliding doors and roof lanterns flood the back of the house with light, even on north-facing NG5 gardens.
- Added property value – a quality rear extension is one of the strongest returns on investment for homes across the Arnold market.
- Keeps your garden usable – we design the footprint to add space indoors while leaving you a practical garden behind.
- Often permitted development – many Arnold rear extensions can proceed without a full planning application, saving time and cost.
- A seamless match – matching brick, render and rooflines so your extension blends with the existing property.

Planning in Arnold
Arnold falls under Gedling Borough Council for planning. Many single-storey rear extensions here are allowed under permitted development, provided they meet the size and height limits: for a detached home you can usually extend up to 4 metres from the original rear wall, and up to 3 metres for a semi or terrace, subject to the larger home extension rules and neighbour consultation.
Height is capped at 4 metres, with eaves no higher than 3 metres if within 2 metres of a boundary. If your Arnold property is in a conservation area, is listed, or has had previous extensions, the rules can differ. We check your specific address and handle any application with Gedling Borough Council for you.
Party Wall Note
If your extension is close to a shared boundary with a neighbour, a Party Wall agreement may be needed. We flag this early and guide you through it.

What Arnold Homeowners Say
We had a rear extension done on our semi in Arnold and could not be happier. The team matched the brickwork perfectly and kept the garden tidy throughout. Our kitchen-diner is now the heart of the house.
From the first survey to sign-off they were straight with us on cost and timing. They sorted all the building regs and the bi-fold doors have transformed our back room. Highly recommend for anyone in Arnold.
Really pleased with our new open-plan space. They handled the permitted development checks with Gedling council and there was no fuss at all. A proper local firm who know Arnold homes.
