Extension costs

[Fetaa]

If you’ve had a house extension or know someone who’s had a house extension recently in past few years - how much was it, how big was it, how many stories and which part of the country?

Single story, about 40m2, budget about 60k spent about 100k.
whatever you think it’s going to cost add a lot more.
lots of dust, hassle and work, even though paying for it. Seriously consider moving as also puts a lot of strain on relationship.

se London got quoted 80 for a single storey permitted development but that was just before covid and it's now impossible to get anyone to even quote for a small job

Large extension and loft conversion. All in will be about £140k
