Rear Extensions Built for Carlton Homes
Carlton is full of solid Victorian and Edwardian terraces, 1930s bay-fronted semis and post-war family homes, many with long rear gardens that are perfect for extending into. A rear extension is the most popular choice locally because it lets you keep the front of your home looking the same while transforming how the back of the house works.
Most Carlton homeowners come to us wanting a bigger kitchen-diner, a family room that opens onto the garden, or a utility and downstairs WC to take the pressure off busy mornings. We handle single-storey rear extensions of all shapes, from a modest 3 metre projection to full-width builds with bi-fold doors and roof lanterns.
Because we work across Carlton, Gedling and the wider NG4 area every week, we know the local ground conditions, the drainage runs and how the building control team here likes things done. That local knowledge keeps your project moving.

Planning and Permitted Development
Carlton falls under Gedling Borough Council for planning. Many single-storey rear extensions here can be built under permitted development rights, which means no full planning application is needed as long as you stay within the limits.
Key Points for Carlton
- Detached homes can usually extend up to 4m to the rear under permitted development, semis and terraces up to 3m.
- Larger single-storey extensions up to 6m (semi/terrace) or 8m (detached) may qualify under the Larger Home Extension prior approval scheme.
- Height is limited to 4m, or 3m within 2m of a boundary.
- Homes in a conservation area or with an Article 4 direction have tighter rules, so always check first.

What Carlton Homeowners Say
Real reviews from rear extension projects across Carlton and NG4.
We had a full-width rear extension on our semi off Carlton Hill and it has completely changed the house. The team were tidy, on time and clear about costs from day one.
Our Victorian terrace near the village centre now has a proper kitchen-diner opening onto the garden. They sorted all the planning and building control without any fuss.
Great local firm. The roof lantern and bi-folds they fitted flood the new room with light. Would recommend to any Carlton family thinking of extending.
