A Guide to the Cost of Renovating
“So how much does a house extension cost...?” This is a question I get asked over and over! And it’s not an easy one to answer as it depends on a lot of different factors.
...yes, yes but how much...? I hear you say!
I will try my best to answer the question and give you a straightforward breakdown of what’s involved. The following figures are based on our work in London where costs are considerably higher than the rest of the country, and are exclusive of VAT and professional fees.
The typical cost per square metre for a single storey rear extension in London is £1,800 – £2,500. So a hypothetical rear extension measuring six by five metres would cost approximately £54,000 – £75,000.
Side return extensions (infilling the rear yard common to Victorian houses) are typically more complicated as they involve removing structural walls, and can cost anywhere between £4,000 – £6,000 per square metre. For a side return extension measuring five by two metres, it could be between £40,000 – £60,000.
Please bear in mind that these figures are for a basic build only! If you are thinking bespoke joinery, underfloor heating, large expanses of glazing, or exposed internal brickwork then the overall cost will naturally increase. Why not discuss your ideas through with us?
