Rear Extension Projects

Residential rear extension projects

Rear extensions are one of the most effective ways to improve an existing home, creating larger kitchen, dining and living spaces while maintaining a clear relationship with the garden.

This archive brings together selected AC Design Solution projects involving rear extensions, including planning applications, permitted development schemes, structural coordination and technical design packages.

For homeowners considering a similar project, our single storey extension service explains the design and planning process in more detail.

Each project responds to the existing property, neighbouring context, daylight, overlooking, structure and planning constraints. The aim is not simply to add floor area, but to create a well-proportioned addition that feels connected to the original building.

Design and planning considerations

Rear extensions often involve decisions around depth, height, roof form, materials, glazing, drainage and the impact on neighbouring properties. Some projects can fall under permitted development, while others require full planning permission, particularly where the property is a flat, listed building, in a conservation area or has previous extensions.

Where a larger extension is being considered, our double storey extension service may be more relevant. For drawing-led projects, see our house extension drawings service.
