@AnonymousBosch yeah, that's what I'm looking for at the moment: turnkey builders in the Northeast that get paid by milestone completion (foundation, watertight structure erected, finished - or something to that effect). Bizarrely, it seems that the UK market is made up of ultra-large housebuilders and smaller/specialised local contractors that need to be managed on-site. Struggling to find a small/medium main contractor that offers a-z construction services.
