The cost of a single storey extension is anywhere between £1,500 to £2,000 per square meter if you live outside of london and in the south east and from £1,200 to £1,500 per m2 anywhere else in the UK.
Kitchen £5,000 to £20,000
Bathroom (according to the level of fittings) £5,000 to £11,000
Shower room £4,500 and £11,000
Flooring £25 to £100 per square metre

Two Storey Extension Cost
A generally-accepted rule to calculate the cost of a two storey extension, is to add 50% extra when both storeys have the same size.
£40,000 + 50%= £60,000
Add 10% for professional fees = £66,000
Add VAT = £79,200
Again, it is very likely that the prices in London and the South East are higher.
