I'm a self build expert and here's my advice for managing your own self build
Briefly

"Before diving into managing your own self-build, it's important to assess whether you're cut out for the role of project manager. Many self-builders take on this task not because they think they'll be particularly good at it, but because they feel like they have no other option - usually due to budget constraints or an inability to find a reliable project manager."
"If you're the kind of person who thrives under pressure and can multitask without getting flustered, then this role might suit you. But if you're easily overwhelmed or aren't particularly comfortable managing others, it might be worth reconsidering."
