What you want is a good building site supervisor, who is experienced in the construction industry in general, the scale of the building under construction in particular and the local region and any peculiarities involved, as well as being fastidious and quality-focused. That's AFTER you've obtained a good, site-appropriate, well-specified design from a good architect.

Having all aspects of a bespoke residential build go well takes a lot of effort, planning, attention, money and luck. I wish you well!
