Home extensions in Carlton
Rear, side, double storey and wrap around extensions, loft conversions and orangeries for homes in Carlton, Netherfield, Colwick and the wider NG4 area.
Planning here is decided by Gedling Borough Council. A lot of local homes have good-sized gardens but narrow side access, which affects both the design and how the build is run. We look at both at a free survey.

Who approves an extension in Carlton
Carlton, Netherfield, Colwick and Gedling village all come under Gedling Borough Council for planning. Mapperley is the one to watch: it is split between Gedling and Nottingham City Council, so homes a few streets apart can deal with different planning departments. We confirm the council for your address at the start.
Planning permission and Building Regulations are separate. Planning looks at size, appearance and the effect on neighbours. Building Regulations look at the construction itself: foundations, structure, insulation, drainage and fire safety, and they apply to almost every extension. You can use local authority building control or a registered building control approver, formerly known as an approved inspector. We handle the coordination either way.

Big gardens, tight side access
Much of Carlton is 1930s bay-fronted semis, with post-war terraces and newer estate homes in between. The semis often have long rear gardens but only a narrow gap at the side. That tends to make a single storey rear extension the first choice for a larger kitchen and dining space, while a double storey extension suits families who also need an extra bedroom or bathroom.
Narrow side access also shapes the build. Where a mini digger or skip can’t get round to the back, spoil and materials are moved by hand or through the house under protection, which adds labour time. We check this at the survey and price it in, so it isn’t a surprise later.
On semis and terraces, most rear extensions are built close to the shared boundary, which usually means serving notice under the Party Wall etc. Act 1996 before work starts. Ground conditions vary from plot to plot, so foundation depths are agreed with building control on site once the ground has been opened up.
Planning checklist for Carlton homes
Some extensions may fall under permitted development, but it depends on the property and any restrictions that apply. Points to check:
- Semi-detached and terraced homes: a single storey rear extension up to 3m deep may be permitted development, up to 4m high.
- Deeper single storey rear extensions, up to 6m on a semi or terrace, can go through prior approval, where Gedling asks neighbours for comments.
- Conservation areas and Article 4 directions: some streets have added restrictions, so check before designing.
- Previous planning conditions: some homes have had permitted development rights removed.
- Party wall notices: usually needed when you build on or near a neighbour’s boundary.
- Building Regulations: needed for almost every extension, with or without planning.
Prior approval is not full planning
Prior approval is a lighter process for larger single storey rear extensions. The council looks mainly at the effect on neighbours. It is quicker than a full application, but work can’t start until the council has agreed or the decision period has passed without a decision.

Carlton extension questions
Gedling Borough Council, along with Netherfield and Colwick. Parts of Mapperley are in Nottingham City Council’s area, so if you live on that side we check which council applies to your address.
Possibly, through prior approval. A single storey rear extension up to 6m deep on a semi or terrace can be notified to Gedling, which consults the neighbours. If the council objects, or the property doesn’t have permitted development rights, a planning application is needed instead.
Yes. It takes more planning: smaller machinery, materials and spoil moved by hand, and protection through the house where there’s no other way round. We assess this at the survey and include it in the quotation.
If you are building on or near a shared boundary, you’ll usually need to serve notice under the Party Wall etc. Act 1996. Neighbours are also consulted by the council on planning and prior approval applications. Talking to them early helps.
As an indicative guide, a single storey rear extension is typically £38,000 to £52,000, and a double storey from around £65,000. Your price depends on size, finish and site conditions, and comes as a written, itemised quotation after the survey.
Most single storey extensions take around 10 to 14 weeks on site, with double storey and wrap around projects taking longer. Design, planning and Building Regulations approval come first. You get a schedule with your quotation.
