No the two companies I contacted about it were happy to remove the earth as part of the package.
From speaking to people that have done similar work I think the container solution is out now, if I ever get to do it.
It'll more likely be a timber and concrete frame.
Would love to hear more on this, it does like a more typical build under ground might be easier/cheaper compared to the cost of buying and manipulating a few storage containers to your needs. You would have to deal with making it suitably weather proof but I cant help but think that a breeze block outer wall would be so much cheaper and you can be more flexible in the size of the room rather than using the fixed dimensions of the containers
If I owned the right place Id love to do this, build under the garden first with entrance steps close to the house then perhaps later build a conservatory that enclosed the entrance making it part of the house
Have you went to building companies (i.e. bricks and mortar) as they will be more willing to push you to do something they are comfortable with rather than what is cheapest however out of their comfort zone.
KaHn
There are a lot of additional considerations and planning (and therefore cost) associated with having the entrance within your home (or building within 2-3 metres of it, depending on who you believe).
Obviously if a done to the highest standards of construction would cost £30k
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.
£160k+ is that from an unreliable builder who's rude? or a plumber who doesn't turn up? or is this a fully loaded man cave with every option from the list?
Fantasy price for the work required.
