Hi, Having an extension built 3m by 10m. Builder priced it up for 1m footings but it looks like I may have to have 2m footings, the BCO is coming back tomorrow to confirm. The builder has warned me its going to add significantly to the costs i.e extra labour, skips etc. and then the obvious cost of the extra concrete. I just wanted to know what the typical cost of readymix concrete is in the SE. The builder is a good guy and is as worried as me at the moment because the block and beams are already on site so if I can't afford to go ahead he's left with the a block and beam floor. I'm pretty certain thats not going to happen because I don't let people down I'm just trying to get an approx additional cost so I'm not too shocked tomorrow. I can get around the extra skips and waste removal because I have an area where the waste can be put in my garden and then level it off (its all sand anyway). He already has the digger on site so hopefully it just the cost of the extra concrete and an extra days work.
