Welcome to Robert Knowles Construction

Robert Knowles Construction has been crafting beautiful, high quality new homes and home remodels since 1983. A father/son owned company in the Portland metro area, we specialize in sustainable building. Our Sustainable Building Methodology™ focuses on three core areas to achieve the green, energy efficient home of tomorrow. This methodology includes building performance, healthy interiors with custom cabinetry and earth friendly finishes, and solar. Whether it is that dream kitchen or bathroom remodel, an addition to your home, or your custom new home, we are uniquely qualified to build what you want while benefiting the planet.

Historically, energy rates double every 10 years. Our mission is to save you energy. Learn more about our methodology.

Our craftsmanship and attention to detail is unparalleled. One area of expertise is historical renovations, as well as modern new construction. We recently won a Builder Excellence 2008 Silver Merit Award for a whole house remodel under $250,000. Check out our work.
