A Complete Guide to Design Build for New Home Construction
Building a one-of-a-kind home is one of the largest decisions most families face.

What Is the Design Build Model?

Unlike the traditional separated model, design build means you have one accountable party responsible for the entire scope, from lot assessment and floor plan creation through framing and interior completion.

A Brother & Brother Builders project team typically includes licensed architects, project planners, and construction specialists who meet regularly. This results in the fact that if a specification is too costly, it gets adjusted immediately rather than becoming a mid-build problem.
The design build approach is especially powerful for complex residential projects because all selections — from window placement to structural systems — is assessed through both a aesthetic perspective and a construction feasibility lens at simultaneously. The outcome is a home that matches the original concept and is delivered without waste.
Why Homeowners Choose Design Build

- Budget Certainty — Estimates are developed collaboratively by the same people doing the design and construction, which greatly limits the difference between quoted and final costs.

- Reduced Risk of Scope Creep — Integrated planning holds modifications to a small number because specifications are confirmed as constructible before they are finalized.
- Less Stress, More Clarity — Homeowners who choose design build consistently describe a more enjoyable building journey compared to coordinating separate design and construction contracts.
