This is what a builder would do in North America, they're the general contractor and will generally budget for you, manage the project and the trades. They'll ensure quality and be your point of contact. Typically where I'm at they charge 15% of the total time and materials of the build.

The builder / GC is in charge of the construction, so when incentives diverge they’re not on the side of the owner. They’re the second party.

That’s why you need a construction supervisor, a third party that’s on your side (if you don’t have the skills, knowledge, or time, to be the supe).

My expectation is that the general contractor's attitude towards quality would be completely random. Some are gonna be great and some are gonna cut every corner they think they can hide from you. And then the buy side of the market isn't sophisticated enough for it to be easy to identify which is which.

And like for renovations, lots will bid the easy project and do it as fast as they can vs ensuring that anything that comes up is addressed well.

It'll likely depend whether it's a fixed cost build or a cost plus. With cost plus this will not nearly be as much of an issue.
