Everything You Need to Know About Design Build for Custom Home Projects
Building a new home is one of the largest investments most families face.

Design build addresses that problem by uniting the whole build under one team.

What Is Design Build?

In contrast to the traditional separated model, design build means you have one point of contact responsible for all phases, from lot assessment and floor plan creation through framing and final details.

A Brother & Brother Builders project team typically includes licensed architects, project planners, and trade partners who collaborate constantly. This results in the fact that if a specification is too costly, it gets caught before breaking ground rather than showing up as an expensive surprise.

The payoff is a home that looks the way you envisioned it and is delivered without waste.
