Founded by GC Barrett Karber, Grain Construction is a Bay Area + LA-based custom home builder specializing in luxury homes and spaces. Our projects include residential, hospitality, commercial, and ground-up home builds.

In Barrett’s decades of experience in construction and furniture design, he found that the industry often forfeits speed and profit over lifespan. By focusing on longevity, quality, and forward-thinking innovation, Barrett established Grain as an antidote to current construction standards. 

Grain takes pride in craftsmanship at the highest caliber and aims to achieve technical perfection. Our expertise in lean construction is fueled by our uncanny ability to creatively solve seemingly unsolvable problems.

our process

In working with a wide range of private clients, interior designers, and architects, we focus on innovative, architecturally-driven design and building that adheres to our signature simple, modern aesthetic.

We select highly-skilled trade partners that adhere to our vision of client-driven craftsmanship. Our partners approach all complexities with excellence and integrity to technical-based building and design.

As a people-first construction company, we are committed to bridging the relationships between clients, subcontractors, architects, and builders while ensuring the client’s needs and wants are elevated at all times. Through our easy-to-use app, our clients can access real-time updates to communicate seamlessly with the team.
