Your Design-Build General Contractor

At DRF Builders, we believe the keys to success lie in communication and collaboration from all stakeholders right from beginning to end. When everyone—designers, architects, engineers, project managers, general contractors—is invited to the table, we foster project buy-in, coordination and efficiency from the get-go. This design-build approach to general contractor services allows us to collaborate with our customers on a higher level without leaving anyone out for a better understanding of the project’s objectives. Plus, our customers only have to deal with one point of contact; no more chasing after contractors for updates. 

Our design-build process

Pre-Construction Planning

We always like to have a good idea of the size and scope of our projects before we hit the ground running; so first, we like establish budgets, plan timelines, and submit necessary permits and documentation

Architectural Design 

We help you find the most experienced and best qualified architects, engineers and other general contractor professionals to make your dreams a reality. 


We handle everything from site preparation, setting the foundation, carpentry, plumbing, roofing, painting, installing flooring, and more.

This is the part of the process where we transition your project from construction zone to business or home: site clean-up, inspections and documentations, and the final walkthrough for approval.
