HAHAHAHAHAHAHA err you'd have thought so, but so far I've had estimates up to £160k+, possibly more if going under the house
I'm having quotes for the same thing at the moment.
Going under the house will cost an absolute fortune in comparison to building away from the house, absolute fortune, underpinning, maybe by a huge amount, architects, planning, structural engineers. I'd move before bothering to go under a house, its not worth the hassle.
I didn't actually mean the best everything just, actual building quality as opposed to a somewhat make shift container, size is obviously a crucial factor in cost as well.
But I wasn't stating 30k as a "thats how much it will cost" I was just saying if option A costs 3 times as much as option B and you can only afford option B then option A isn't feasable.
We've got a huge long garden here, forget exactly how long around 100ft..... options indeed, though its fairly narrow with the length, how far would you have to be from the boundary of property for no planning permission situation? If its like 2-3 metres I can have an awesom 80ft long 1m wide corridoor
AS for the quotes you've had, yeah, we got the front windows done, the random quotes you get and random people you wouldn't trust with a bargepole, the number of companies that say they'll come have a look and never turn up or return calls, the amount that clearly want you to suggest a price so they can make up some numbers that suit your budget... its pretty disgusting. Took a ridiculous amount of time to find some people to do quality work.
We need a kitchen done, bathroom done, some joists replacing in bathroom and so ceiling done(its above kitchen) and heating(boiler in the kitchen/dining room at the moment) so trying to get it all done in one go. Again trying to find someone you remotely trust to not massively screw you on cost or do crap work is seemingly almost impossible.
