How much did your extension cost?

Ours would be widening our house by about 6ft, 2 stories. Increasing size of a bathroom and living room and adding a small study. I'm greater London. I know it depends on a lot but... rough ideas of range of price? Xx

In London maybe £2k per sqm per floor these days as a starting point?
I dunno exactly.

I had a two up, two down extension that doubled the size of my house. South East 2016 £115,000.
