Our Story

Read More

Confluence Design-Build, Inc. has been serving the Portland Community since May 2003. From foundations to fine woodworking, they have consistently produced high-quality, reliable, long-lasting work. Whether it's a brand new home, a remodel of a well-loved home, or an important business-related building, the builders at Confluence are happy to use their years of varied experience to complete your project on schedule and within your budget, all while providing the excellent craftsmanship necessary to make your vision a reality.

In addition to his skills as a craftsman, Matt Mansfield (owner and lead builder) provides complete project management. Not only will he be on site every day providing hands-on, in-house service customized to meet your needs, he has a network of reliable, trustworthy subcontractors. For our clients, this translates to streamlined communications and tight control over quality, schedule, and budget. 

We enjoy the creative process of design as much as the construction phase. In our renovations, we take particular pride in matching existing details and finishes to provide a seamless transition from old to new. We work with a wide variety of styles and materials, we know how to build things that last, and we stand behind our work.
