Bedroom Extensions Built for Long Eaton Homes
Long Eaton has a real mix of housing – lace-era terraces around the town centre, 1930s semis along Derby Road and Curzon Street, and newer estates towards Sawley and Long Eaton Green. Most of these homes share one problem: not enough bedrooms for a growing family. Moving house in the NG10 market often costs far more than building the space you need.
A bedroom extension adds a proper double bedroom, and often an en-suite too, without the stress of moving. The most common route in Long Eaton is a double storey extension to the rear or side, giving you a bigger kitchen or living room downstairs and a new bedroom above. Where a home has an attached garage, building a first-floor extension over it is often the most cost-effective option of all.
We survey your home, check what the plot and party walls will allow, and design a bedroom extension that matches your existing brickwork and roofline so it looks like it was always there. Going from three bedrooms to four is one of the strongest value-adding moves you can make on a Long Eaton semi.
Best For
Growing families in 2 and 3 bed semis, homeowners adding an en-suite master bedroom, and anyone with an attached garage that could carry a first-floor bedroom above it.
Typical Value Added
Adding a fourth bedroom to a three-bed Long Eaton semi can add roughly 15-20% to its value – often more than the build cost itself.
Benefits of a Bedroom Extension in Long Eaton
- Cheaper than moving – stamp duty, agent and legal fees on a bigger NG10 home quickly outstrip the cost of building a bedroom you actually designed yourself.
- Strong added value – moving from three bedrooms to four puts your home in a different price bracket with local buyers.
- Space for a growing family – separate rooms for children, an en-suite master, or a comfortable guest room for visiting family.
- Downstairs gains too – a double storey extension gives you a bigger kitchen or living space beneath the new bedroom for little extra cost per square metre.
- Stay in the area you like – keep your schools, neighbours and easy access to Long Eaton station and the M1 while gaining the space you need.
- Modern comfort – new bedrooms are built to current insulation standards, so they are warm, quiet and cheap to heat.

Do You Need Planning Permission?
📋 The short answer
Most bedroom extensions in Long Eaton involve a second storey, which usually needs full planning permission from Erewash Borough Council. Single storey elements may fall under permitted development, but anything raising the roofline or building over a garage will normally need an application.
Key points the council looks at: the effect on neighbours’ light and privacy, matching materials, and keeping the extension in proportion to the original house. Semis on streets like College Street or Wilsthorpe Road often also need a Party Wall agreement with the neighbour. We handle the drawings, the application and the party wall process for you – and our planning success rate is 100%.

What Long Eaton Homeowners Say
“We were about to sell our three-bed in Long Eaton until the team suggested a double storey extension. We now have a fourth bedroom with en-suite and a much bigger kitchen. Should have done it years ago.”
“They built a bedroom over our garage and you honestly cannot tell it was not part of the original house. Brickwork matches perfectly. Planning with Erewash was handled entirely by them.”
“Tidy, polite and on schedule. With three kids in a two-bed near the town centre we were desperate for space. The new bedrooms have changed how we live. Great communication throughout.”
