Double Storey Extensions Arnold
Add a bigger kitchen downstairs and an extra bedroom or bathroom upstairs in one build. Our double storey extensions give Arnold homes the space a growing family needs without the cost and upheaval of moving.
From the semis around Gedling Road to the larger detached houses near Arnot Hill Park, we design two storey extensions that suit your home, your budget and the way your family lives.

Two floors of new space in one build
Arnold sits on a slope in parts, and many homes here have decent plots but tight internal layouts. A double storey extension is the smart answer when you need more than a single downstairs room. You get an open kitchen diner or larger living space on the ground floor, and a new bedroom, en suite or family bathroom above it, all under one roof.
Because the groundwork, scaffolding and roofing are shared across both floors, a two storey extension usually costs less per square metre than doing two separate projects. For families in Arnold who love the schools, the parks and the tram links into the city, it is often far cheaper than trading up to a bigger house and paying stamp duty and moving fees.
We handle the whole job from first drawings to final decoration, working with Gedling Borough Council on planning and building control so you do not have to chase paperwork.

Why homeowners in Arnold choose a double storey
- More bedrooms without moving – add a fourth or fifth bedroom to a family semi and avoid the cost of a bigger house.
- Better value per metre – sharing foundations and roof across two floors keeps the cost lower than two separate builds.
- Kitchen and bedroom in one go – open up the ground floor and gain an upstairs room in a single project.
- Adds real resale value – a well built two storey extension is one of the strongest ways to raise value in the Arnold market.
- Keeps your garden – building up as well as out means you use less of your outdoor space than a large single storey.
- Room for modern living – space for a home office, utility and en suite that older Arnold houses often lack.

Do you need planning permission?
Many two storey extensions in Arnold can be built under permitted development, but the rules are tighter than for single storey work. Upper floors must sit within set limits from the rear wall and boundaries, and there are restrictions on side facing windows to protect neighbours’ privacy. We check your exact situation before we start.
Arnold planning points to know
- Two storey rear extensions are usually limited to around 3 metres deep under permitted development.
- Upper floor side windows often need obscure glazing and fixed lower panes.
- Homes near conservation frontages or on corner plots are more likely to need a full application.
- All two storey work needs building regulations approval regardless of planning.
We manage every submission to Gedling Borough Council and have a 100 percent planning success rate, so you can build with confidence.

What Arnold homeowners say
Real reviews from double storey projects in and around Arnold.
We went from three to five bedrooms with a two storey extension on our Arnold semi. The team handled the Gedling planning and finished on time. The upstairs en suite is the best decision we made.
Fantastic job on our double storey rear extension near Arnot Hill Park. New kitchen below and a big bedroom above. The brickwork matches the original house so well you cannot tell where the old ends.
