THE HONEST GUIDE
Planning permission for extensions in Nottingham
Most extensions need less permission than people fear. Here is how the rules actually work, which council you deal with, and what it costs.
Permitted development: the free pass most people have
Permitted development (PD) rights let you extend without a planning application, provided you stay inside the limits. For most Nottingham houses that means: single storey rear extensions up to 3 metres deep on semis and terraces or 4 metres on detached homes (extendable to 6 and 8 metres via prior approval), maximum height 4 metres, materials in keeping with the house, and no more than half the garden covered including outbuildings.
Loft conversions get their own allowance: 40 cubic metres on terraces, 50 on semis and detached, which covers most dormers. Garage conversions rarely need permission at all since the structure barely changes.
PD does not apply to flats or maisonettes, and some estates and conservation areas have had rights restricted. A Lawful Development Certificate (£129) is worth getting even when no permission is needed; it is the paperwork that satisfies solicitors when you sell.
When you do need permission
- Double storey extensions in most cases, and anything forward of the front wall
- Side extensions on corner plots or facing the highway
- Anything in a conservation area beyond modest limits
- Schemes exceeding PD size limits
A householder application costs £258, targets an 8-week decision, and approval rates for sensible domestic schemes are high across all the Nottingham councils. The trick is designing to the local pattern: matching materials, respecting neighbour light, keeping street-facing changes modest.
Which council are you actually in?
Greater Nottingham is carved up more finely than people expect: Nottingham City covers the city proper including Sherwood, Wollaton and Clifton; Rushcliffe covers West Bridgford and south of the river; Gedling covers Arnold, Carlton and Mapperley; Broxtowe covers Beeston, Stapleford and Eastwood; Ashfield covers Hucknall. Same national rules, different local plans and conservation areas. We deal with all five weekly.
Building regulations: always required
Whatever the planning route, building regulations apply to every extension: structure, insulation, drainage, electrics, fire safety. Approval comes via the council or a private approved inspector, costs £500 to £900 for a typical extension, and ends with the completion certificate your future buyer’s solicitor will ask for. Our plans and design service covers the drawings both stages need.
Frequently asked questions
How long does planning permission take in Nottingham?
Eight weeks is the statutory target for householder applications and the local councils mostly hit it. Add 3 to 4 weeks beforehand for drawings, and factor holidays; a January submission builds in spring.
What happens if I build without permission?
The council can require retrospective permission or, in the worst case, alteration or removal, and an unauthorised extension will surface in any future sale. Given how generous permitted development is, there is rarely a reason to gamble.
Do I need planning permission for a loft conversion?
Usually not; most dormers fit within PD volume limits. Front-facing dormers and conservation areas are the exceptions.
