Neither structure is automatically cheaper, simpler, safer, or more complete. The practical difference is who contracts for, coordinates, pays for, documents, and corrects each scope.
Short answer: Compare a turnkey or bundled proposal with direct hiring by using the same line-by-line responsibility and closeout matrix. For the home, freight, delivery, site work, foundation, setup, utilities, trades, exteriors, permits, inspections, corrections, warranty, cleanup, and final records, name who contracts, performs, coordinates, supplies, schedules, pays under the written agreement, corrects, warrants, and proves completion. A package label does not establish included scope, single-point responsibility, total project cost, savings, timing, or outcome.
