Pre-construction can be a real phase
Layout decisions, selections, plans, permits, trade coordination, and material ordering may happen before visible construction begins.
Rough work comes before finishes
Framing and the electrical, plumbing, and mechanical rough-ins typically need to happen before insulation, drywall, flooring, trim, cabinets, and final fixtures.
Bathrooms and custom features add sequencing
A bathroom, egress opening, wet bar, built-ins, or significant utility relocation can introduce additional inspections, lead times, and dependencies.
