A contractor charges 40–60% of material cost for labor (general contractor — more, add 15–20% management). Self-build saves labor but: your time has value (you could be earning), mistakes and rework typically cost 10–20% of materials, timelines run 1.5–2× longer. The most common hybrid: shell by contractor, finishing DIY.
