Bedroom Extension Carlton
Add a proper new bedroom to your Carlton home without the cost and upheaval of moving. We design and build bedroom extensions across Carlton, Gedling and Netherfield, usually as a first-floor addition over an existing single-storey structure or as part of a double storey extension.
From the first survey to the final coat of paint, one local team handles the design, planning application, structural work and finish.

More Bedrooms Without Moving House
Carlton has a strong mix of Victorian terraces, 1930s semis and post-war family homes, and many of them share the same problem: two or three bedrooms that a growing family has simply outgrown. A bedroom extension solves that. Instead of paying stamp duty, agent fees and moving costs to buy a bigger house, you add the space where you already live.
The most common route in Carlton is building above. Semis on roads around Carlton Hill and Cavendish Road often have a single-storey kitchen or garage that will happily take a first-floor bedroom on top, sometimes with an en-suite. Where the plot allows, a full double storey rear extension gives you a bigger kitchen downstairs and a new bedroom upstairs in one project. On terraces closer to Netherfield, a dormer loft conversion is often the smarter way to gain a bedroom, and we can advise on that at the survey.
We know the local ground conditions, the typical brick and roof-tile matches for Carlton streets, and how Gedling Borough Council’s planning team approaches first-floor additions. That local knowledge keeps your project moving and keeps the finished extension looking like it has always been part of the house.
Best For
Growing families in Carlton semis and terraces, homeowners adding an en-suite master bedroom, and anyone who loves their street but needs one more room.
Value Added
An extra double bedroom typically adds around 10-15% to the value of a Carlton home, often more when it comes with an en-suite.
Benefits of a Bedroom Extension in Carlton
- Cheaper than moving – extending usually costs far less than trading up to a four-bed in the same area once fees and stamp duty are counted.
- Stay in the area you know – keep your school catchment, neighbours and easy access to Carlton Square and the tram and train links into the city.
- Real added value – an extra bedroom is one of the most reliable ways to lift the sale price of an NG4 home.
- Designed around your family – master suite with en-suite, a child’s room, or a guest bedroom that doubles as a home office.
- Warm and quiet – new rooms are built to current insulation standards, so they are often the most comfortable rooms in the house.
- One local team – design, structural calculations, planning, build and decoration handled end to end.

Planning Permission in Carlton
📋 What to expect
Most bedroom extensions in Carlton need a planning application, because first-floor and two-storey additions fall outside many permitted development limits. Gedling Borough Council will look at the height, how close the new room sits to your boundary, and the effect on your neighbours’ light and privacy. Two-storey rear extensions normally need to stay at least 7 metres from the rear boundary. We prepare the drawings, submit the application and handle Building Regulations approval as standard, and we will tell you honestly at the survey if your plans need adjusting to get approved.

What Carlton Homeowners Say
“We were about to put our Carlton semi on the market when they suggested building a bedroom over the garage instead. It cost far less than moving and we now have a lovely master with an en-suite. The brick match is spot on.”
“The double storey extension gave us a fourth bedroom for our daughter and a bigger kitchen. Planning with Gedling was handled entirely by them and went through first time. Tidy workers, on budget.”
“Honest advice from day one. They told us a loft room would suit our terrace better than extending, priced both, and let us choose. We went with the first-floor bedroom and could not be happier with the finish.”
