Double Storey Rear Extension Long Eaton
A double storey rear extension adds space on both floors at once – a bigger kitchen and living area below, plus an extra bedroom or bathroom above. For the price of one build, you get twice the floor area.
We design and build two storey rear extensions across Long Eaton, from Victorian terraces near the town centre to semis around Sawley Road and Wilsthorpe. Free site surveys, fixed quotes and full planning support.

Two Floors of Extra Space at the Back of Your Long Eaton Home
Long Eaton has a great mix of housing – lace-era terraces near the canal, 1930s semis off Derby Road and newer estates towards Sawley. Many of these homes have generous rear gardens but tight kitchens and only three bedrooms. A double storey rear extension fixes both problems in one project.
On the ground floor, most of our Long Eaton clients open up the back of the house into a large kitchen-diner with garden views. Upstairs, the same footprint gives you a fourth bedroom, a main bedroom with en-suite, or a proper family bathroom. Because the roof, foundations and scaffolding are shared across both floors, the cost per square metre is noticeably lower than building two separate single storey projects.
Long Eaton sits within Erewash Borough Council’s planning area, and we know how their planning team assesses two storey rear additions – especially around neighbour privacy and the 45-degree rule. We prepare drawings that get approved first time, then build to a fixed price with our own trusted trades.
Every project starts with a free site survey. We will look at your garden depth, drains, party walls and roof line, then give you an honest view of what will work and what it will cost – before you spend a penny.
Best For
Growing families in Long Eaton who need an extra bedroom and a bigger kitchen, and want the best value per square metre from a single build.
Typical Timescale
Around 12 to 16 weeks on site for most Long Eaton double storey rear extensions, plus 8 to 10 weeks for design and planning beforehand.
Benefits of a Double Storey Rear Extension in Long Eaton
Two floors of space, one build, one set of foundations – here is why it makes sense.
- Best value per square metre – foundations, roof and scaffolding are shared across two floors, so each metre costs less than a single storey build.
- Extra bedroom and bathroom – move from a three-bed to a four-bed layout, which is exactly what the Long Eaton family market wants.
- Bigger kitchen-diner – open up the ground floor into a sociable kitchen, dining and living space that looks onto the garden.
- Strong added value – a well-built two storey rear extension typically adds more to a Long Eaton home’s value than it costs to build.
- Stay put, avoid moving costs – skip stamp duty, agent fees and the stress of moving out of a street and school catchment you like.
- Designed to match your home – brickwork, roof tiles and window styles chosen to blend with your existing house, whether it is a terrace or a semi.

Planning Permission in Long Eaton
What you need to know
Double storey rear extensions almost always need full planning permission – they fall outside standard permitted development in most cases. In Long Eaton, applications go to Erewash Borough Council, and the key tests are neighbour privacy, overshadowing and the 45-degree rule from next-door windows. Extensions must normally stay at least 7 metres from the rear boundary and use materials that match the existing house. Terraced and semi-detached homes will usually need a Party Wall agreement with neighbours too. We handle the drawings, the application and the Party Wall process for you, and we hold a 100% planning success rate on the schemes we submit.

What Long Eaton Homeowners Say
“We went from a cramped three-bed to a four-bed with a huge kitchen-diner. The team handled the Erewash planning side completely and the build finished a week early. Our Long Eaton semi feels like a different house.”
“Fixed price, tidy site and constant updates. The double storey rear extension gave us a main bedroom with en-suite upstairs and a family room below. Neighbours on our Long Eaton street keep asking who built it.”
“They sorted the Party Wall agreement with next door, the steels, everything. We stayed living in the house through the build and it was far less disruptive than we feared. Best money we have spent on our home.”

Most Long Eaton projects fall between £58,000 and £145,000 depending on size and finish. A typical 4m x 5m two storey rear extension sits around £80,000 to £105,000 before the kitchen and bathroom fit-out. We give a fixed written quote after a free survey.
Yes – most of our Long Eaton clients stay at home throughout. We build the new structure first and only knock through into the existing house near the end, keeping the property secure and weathertight the whole time.
If your Long Eaton home is terraced or semi-detached, almost certainly. Foundations near a shared boundary trigger the Party Wall Act. We serve the notices for you and can recommend a local surveyor if a formal award is needed.
Plan for around 8 to 10 weeks of design and planning, then 12 to 16 weeks on site for most Long Eaton projects. Larger builds or high-end fit-outs can take a little longer, and we confirm a build programme before we start.
