How much info to provide? i don't want exact costings but knowing if I could get the basic structure in and signed off for 30-50-100k?
It's about 3.8x3.6m, foundations are expected to be suitable already.
Ideally steels and timber not brick construction.
would expand the box room and need to tie into the main pitched tiled roof,
2 windows,
No urgency to do the CH or electrics if it keeps the costs down initially as it will open out the existing box room where services can remain.Any indicative costing you could provide would be really appreciated.

Here you go: https://costmodelling.com/building-costs
So many variables - material choices, site access, roof shape, height, how it joins the existing, services etc etc, but it definitely won’t be £100k (£7000/sqm) and it’s quite unlikely to be £30k (£2000/sqm) these days unless there are lots of things on your side (experience, knowledge, contacts mainly). £50k ought to be more than enough unless it’s super complicated.

IME you’ll be under a lot less stress if you have more than enough ( double !) in the bank to cover the “what the internet says it might” cost of the project and then specify and tender the project competitively to get value and give you wiggle room etc. Have a professional design it and do a line by line schedule of works to be costed.
Don’t forget VAT 20% obvs and fees 10-15% of construction on top of those indicative pSm rates btw.

But more info required really?
Whilst I’m not extending I’ve got pretty detailed costings for a variety of works if they’re useful to anyone.
Slightly nervous about openly posting use to recent friction in some of the other threads!
