Pitched and lean-to roof rear extensions in Suffolk
Lean-to, gable and hipped roofs that give a vaulted ceiling. We design and build rear extensions across Suffolk, from Ipswich and Lowestoft to Bury St Edmunds, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Pitched roofs suit the cottages and slate-roofed houses in parts of Suffolk. Post-war semis and newer estates are typical of Suffolk, and many have room for a full-width extension. Shrinkable clay is common in the East of England, so foundations near trees and hedges are designed to NHBC-style depth guidance.
How much does a pitched-roof rear extension cost in Suffolk?
Guide prices for a pitched-roof rear extension in Suffolk start from our East of England rate of £2,120–£3,440 per square metre, including VAT. East of England prices run slightly above our West Midlands baseline; clay soils near trees are the main foundation variable.

| 4 m wide × 5 m deep (20 m²) | £42,500–£69,000 |
Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission in Suffolk?
In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part is 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 Suffolk?
We cover 12 towns and districts in Suffolk, including Ipswich, Lowestoft and Bury St Edmunds.
