I've been quoted £60K for this extension. does it sound reasonable?

[ForCyanViewer]

Long and short of it... we've had a builder attend this week and draw up a quotation. £60K exc VAT. It seems reasonable but I wanted to get some wider opinions and my plan is to get another quote or 2. Would appreciate the wider groups perspective

Details and my costy project link below

We’re adding a single-storey rear extension (3 m × 3.4 m) across the back of our kitchen-diner to make one bigger, brighter open-plan space, with bifold doors opening onto the garden. Alongside the build we’d like underfloor heating, large-format porcelain floor tiles, new skirting and full decoration.

You’d be better checking costs specific to your local area…and get at least 2-3 quotes.

Im in Edinburgh but paid £59k for a double storey side extension (2 bedrooms one being ensuite). That was 2 years ago.

thanks @Mum2Fergus the costy tool i used provides an estimate which was a little bit higher than what he quoted but it obviously doesn't have the benefit of a full walkaround. thanks for sharing your quote

70k for 10m2!! That is outrageous unless you are in zone 1 London
We are in zone 6 London and it wouldn't even cost half that

Yikes

I’d be surprised if you could anyone to do any kind of extension for 30k plus VAT.

ive just been quoted 5.5k plus vat to change a 3.5m x 1.5m hall from suspended floor to solid concrete. That is to concrete finish only. I’m in Oxfordshire.

This ^

A neighbour recently had two quotes for a single storey extension similar size to the OP's that came in at 80k and 100k (both plus VAT). We're in West Sussex.

We paid 45k for a slightly larger single storey extension about 12 years ago and the cost of labour/materials have rocketed since then.

Sounds very reasonable

Please send me their details because even paying for their hotel would be worth it.

We were quoted similar but it didn't include any flooring or internal plastering.
