Double Storey Extensions Long Eaton
Adding two floors of space is the most cost-effective way to grow a Long Eaton home without losing a large slice of your garden. Whether you own a bay-fronted semi off Tamworth Road or a 1930s detached near West Park, a double storey extension gives you a bigger kitchen below and an extra bedroom or bathroom above.
We handle everything from the first site survey through to Building Control sign-off, so you get one local team who knows Erewash Borough Council and how Long Eaton properties are built.
- ★ Two floors of new space in one build
- ★ Erewash planning handled for you

More room upstairs and down, built for Long Eaton homes
Long Eaton has a lot of Victorian and Edwardian terraces, interwar semis and postwar detached houses, and each type suits a double storey extension in a slightly different way. A rear double storey on a terrace off Derby Road can open up a galley kitchen and add a fourth bedroom above. A side and rear return on a semi near Trent College can create an open-plan family space downstairs with an en-suite master above.
Because a double storey extension reuses one set of foundations and one roof line for two floors, it usually gives you the lowest cost per square metre of any extension type. For growing Long Eaton families who love the area and the local schools, it beats the cost and upheaval of moving to a bigger house in Sawley or Draycott.
We match new brick and render to your existing elevation, keep the pitch of the new roof sympathetic to the street, and design the internal layout so it flows naturally with the original house rather than feeling bolted on.
Why Long Eaton owners choose two storeys
Land values around NG10 make extending far cheaper than trading up. A well-built double storey extension typically adds more value than it costs.
Local knowledge
We work with Erewash Borough Council week in, week out, so we know what tends to get approved on Long Eaton streets.
Why a double storey extension works well in Long Eaton
- Best value per square metre – one build gives you two floors, so your cost per room drops compared with a single storey or loft alone.
- Keep more garden – you gain living space upstairs without eating into the modest rear plots common on Long Eaton terraces and semis.
- Extra bedroom and bathroom – ideal for families near Brooklands or Wilsthorpe schools who need a fourth bedroom or a second bathroom.
- Adds strong resale value – a three-bed becoming a four-bed with two bathrooms is one of the most sought-after homes in the NG10 market.
- Stay in the area you love – keep your school catchment, your Long Eaton neighbours and your links to the train station and M1.
- Modern energy performance – new walls, roof and glazing are built to current standards, lowering running costs across the whole home.

Planning rules for Long Eaton double storey extensions
Double storey extensions are larger than single storey ones, so they usually need full planning permission from Erewash Borough Council rather than falling under permitted development. Rear two-storey extensions have tighter limits, and a rear extension must not extend beyond the original back wall by more than three metres on most Long Eaton houses.
What to keep in mind
- Boundary distance – upper floors within seven metres of the rear boundary can be restricted, common on smaller NG10 plots.
- Neighbour windows – we design to avoid overlooking, which is a frequent Erewash concern on close-set terraces.
- Party Wall Act – most Long Eaton semis and terraces need a party wall agreement, which we help arrange.
- Matching materials – the council prefers brick and roofing that match the existing street scene.
We handle the whole application for you and have a 100% planning success rate on the projects we take on across Long Eaton and the wider Erewash area.

What Long Eaton homeowners say
Real feedback from double storey extension projects across NG10.
We added a two-storey extension to our semi near Trent College and gained a huge kitchen and a fourth bedroom. The team knew exactly what Erewash would approve and the finish matches our old brickwork perfectly.
Great value compared with moving. Our Derby Road terrace now has an en-suite master upstairs and open-plan living below. Planning went through first time and the price was exactly what they quoted.
Tidy, reliable and local. They handled the party wall agreement with our neighbour and kept us updated every week. We would recommend them to anyone in Long Eaton thinking about a double storey.
