Will the council need to approve it?
In England an annexe that stays part of the household and connects to the house is assessed as an extension, but its size usually takes it beyond permitted development, so a householder application describing the ancillary use is the normal route.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).
Extensions in and around Loughborough
Postcode districts we cover around Loughborough include LE11, LE12. The same team covers Coalville (8 miles), Leicester (9 miles), Oadby (12 miles), Melton Mowbray (13 miles), all within easy reach.
Long Eaton, in Derbyshire, is roughly 10 miles from Loughborough and also on our list. The East Midlands has plenty of inter-war and post-war semis and detached houses with room to extend, alongside Victorian terraces in the towns.

When an annexe extension makes sense
- Relatives who need support close by
- Homes with a large side or rear garden
- Multi-generational families
Accessibility is cheaper to design in than to retrofit. Level access, a 900 mm door width, a level-access shower and space to turn a wheelchair can all be planned into the footprint for little extra cost.

Annexe extension questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Loughborough, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Who do I contract with for an annexe extension in Loughborough?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Do you cover all of Loughborough?
Yes. We cover Loughborough and the surrounding parts of Leicestershire. Site visits are free and there is no obligation.
How much does an annexe extension cost?
Our guide range is about £1,900 to £3,610 per m² including VAT. A one-bedroom annexe of about 35 m² is typically £79,500 to £100,000 at standard spec in Loughborough.
Can the annexe have its own front door?
Yes, many do, but it should still connect to the main house to stay clearly part of it.
