Extension quote- is this reasonable?

49IM

I had a quote last year for a slightly smaller footprint single-storey extension and without your complications such as a steel, velux windows, special foundations - and my best was £20,000.

So it's not way off, I'd say.

There are a couple of items in there that are "the sorts of things that tend to be pricey" - which I suspect are fixing the "lowest cost possible".

Yours isn't a standard "dig a hole, pour concrete in, stick this new bit onto the old bit" type of extension .... and those big windows never come cheap.

I'm shortly to get some quotes for a 2.5m x 6m extension .... I do hope mine's cheap

Hi would you be able to give me the builders details who gave you this quote as I live in Liverpool and I'm looking for a similar sized extension.
Thanks.

2 grand a square meter especially with specialist work sounds reasonable.

Sounds reasonable to me too. If normal foundations and a mid-range finish, i would estimate £1,800 per square metre (excluding VAT), specialist foundations and other things like Velux windows will increase that.

We had a 3.6mx3m extension priced up on the back of the garage - it needed standard foundations but had a sloped roof. The basic building work came in at £15k+VAT without any of the internals, plastering, windows, door, plumbing, electrics or fancy foundations you need. In the end we converted the garage - twice the size for roughly the same cost.

Your price does not sound unreasonable although I would certainly get a couple more to compare.

Posting back late but ours sounds very similar to yours.

We've had a couple more quotes; one of which was almost half the price and the other at 2/3 of the first (so £13k and £18k exc. VAT).

It just shows what kind of variance you get.

£13k sounds suspiciously cheap - esp given the specialist nature of your footings. I'd be really wary of going with that. £1k PSQM is the absolute minimum you would expect to pay for a very straightforward and basic extension.
Good luck with your plans!
