At Big River Builders, we believe cost-plus contracting delivers the most transparent, flexible, and ultimately successful building experience—especially for high-quality custom homes and remodels.
Under a cost-plus agreement, you pay the actual cost of construction plus a clearly defined builder’s fee. This structure allows you to see exactly where your money is going, rather than relying on assumptions or padded contingencies built into a lump-sum price. Every cost is documented and visible through Buildertrend, giving you real-time access to the live project budget, invoices, and progress updates.
Cost-plus also provides critical flexibility. Design details naturally evolve as a project moves from concept to construction, and unforeseen conditions can arise—particularly in custom homes and remodels. With a lump-sum contract, these changes often result in change orders that can feel disruptive or adversarial. In a cost-plus model, adjustments are integrated smoothly, priced transparently, and aligned with your goals, without compromising quality or trust.
Most importantly, cost-plus aligns incentives. Rather than protecting a fixed number, our focus stays where it belongs: delivering the highest level of craftsmanship, maintaining schedule control, and helping you make informed decisions at every step. You retain control over scope and finishes, and we serve as your advocate—guiding choices, managing costs, and keeping the process collaborative from start to finish.
For clients who value transparency, flexibility, and a true partnership throughout construction, cost-plus is the most honest and effective way to build.
