How much will an extension cost me?

[CormoranStrike]

I’m looking to add one room on the back, possibly with a toilet, single story.

How much might this cost - I live in Scotland, if regional variations come in to play.

In London and the South East, the average cost per m2 is around £1,500-£2,000+. For two-storey extensions, add 50% to the cost of a single-storey extension. If you want to add a bathroom or kitchen, add £5,000-£10,000.

We had a kitchen extension which was £15000 for the building and electrics.
