Many thanks Gus, lots to digest there.
I'd say we have a fair experience level - completed 2 detached new builds in 2023, traditional block & natural stone build, (hubby is a stonemason) we used b&b floor and lots of very expensive Kingspan!!
I project managed but we had a MC for the shell as not done one before- we were on site everyday throughout though as it was a learning journey for us(done a fair few refurbs and moving onto new build for our property business) We had lots of involvement right through planning (and appeal!) and with the regs drawings but we're led by the architect (more old school) so a raft didn't come into it as he suggested cost prohibitive - was a project to sell so we were more profit driven, though the houses were A rated & beautiful!
This one is for us to live in long term, we will both be on-site throughout 24/7, so heavily involved, want to 'diy' as much as possible. We have time to spend and happy to ensure everything is properly detailed.
Yes, the woodcrete is for us to diy (been back n forth with the options and feel it meets our needs longterm)
I am quite a detailed person, I like to understand all the elements and make a well informed choice, if a plan says x then I will ensure it is x not x+1 so, I'd like to think we're up to the challenge but, you don't know what you don't know! And, never sure who's opinion to trust hence the post to gather info & opinion.
