Pitched and lean-to roof rear extensions in Essex
Lean-to, gable and hipped roofs that give a vaulted ceiling. Rear extensions in Essex: we cover 32 towns including Southend-on-Sea, Basildon and Colchester, with design, approvals and the build under one contract.
Pitched roofs suit the cottages and slate-roofed houses in parts of Essex. Essex mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.
How much does a pitched-roof rear extension cost in Essex?
For Essex we work from the East of England rate: £2,120–£3,440 per square metre of new floor, including VAT, standard specification. East of England prices run slightly above our West Midlands baseline; clay soils near trees are the main foundation variable.
| Size | Guide price inc VAT |
|---|---|
| 3 m wide × 4 m deep (12 m²) | £25,500–£41,500 |
| 4 m wide × 5 m deep (20 m²) | £42,500–£69,000 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission in Essex?
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres within 2 metres of a boundary.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.

FAQ
Questions people ask
Will a lean-to fit under my windows?
We check the sill heights at the survey; low windows usually mean a flat roof instead.
Are roof windows allowed?
Yes; they are the usual way to bring light into a pitched-roof extension.
Is a pitched roof more expensive?
Slightly, typically a few per cent more than a flat roof of the same area.
Do you cover all of Essex?
We cover 32 towns and districts in Essex, including Southend-on-Sea, Basildon and Colchester.
Who builds the extension?
Vetted building teams working under contract to us; your contract is with S&K Property Investments and Improvement Ltd.
