Hi all. We have been aiming to build an ICF house and have been going nearly 4 years now and have come to a complete standstill. What with very slow architects, very slow planning, Covid, discovering the house has been designed too big for the plot and massively over budget, we find ourselves with a hole in the ground and being in dispute with the professionals. We have read on the forum of others in similar circumstances where the architect has not kept to budget and are left with a house that cannot be built. In short, we are in need of a revamped design that is smaller, very simple, no fancy frills, that is within budget and can be built quickly. More of a long box shape (we will have a basement with 2 floors on top). Any advice on the simplest design to keep costs down would be great. We have lost trust in many of the professionals we have been involved with and just want to leave it all behind and get something done. We are living in temporary accommodation on site and heading for the Winter and are bracing ourselves for that! Looking at other posts quite a few have recommended doing a design yourself and then getting someone to draw up the design for planning - not an architect, but someone else. We have come up with a design ourselves scaling everything down and making it simpler, but we need to know if it will work and to get plans drawn up. Can anyone recommend a way forward, maybe even someone who can do these drawings? We are based about 10 miles south of Birmingham. It would be good to find someone used to working with ICF. We are contacting ICF builders as our original builders are now booked up. Someone on this forum mentioned using a design and build service as this may be a more joined up way of doing things. Any thoughts on that? Anything to keep costs down and get through planning as speedily as possible. We're feeling a little desperate as many avenues we go down end up being dead ends or we don't feel we can trust people. We've thought about kit houses, but experiences using these have been very mixed on the forum. What we don't want is to go from the frying pan into the fire. I don't think our mental and physical health can stand it!! Sometimes you think why did we ever start this, but we are where we are and I'm sure it'll work out in the end! Any recommendations would be gratefully received. Thanks!!
