We started nearly 7 years ago - I've been recording every cost including what we are spending on the soft & hard landscaping, boundary fences, etc I'm hoping we will be between 1,000 & 1,200. Stuff has got very expensive in the last two years - we would be no where near that if we were building now. I've got 6 spare 8x4 x 140mm celotex sheets that were left over from 5 years ago - fantastic return, wish I had more left over! I will report back what we finish at once I put the VAT claim in..... hopefully this summer.
