CTA Design Builders

CTA Design Builders has been a successful architect-led, design-build practice in the Pacific Northwest for over 20 years. Located in Seattle, we specialize in designing custom residential homes, additions, and remodels. Whether contemporary or traditional in design, urban or rural in setting, we work with our clients to create timeless homes that become the place they most want to be.

Our Philosophy

Your home is your most personal of places; a sanctuary where you can express what is most meaningful to you. This belief guides our work: we design homes and remodels that are functional, beautiful, and a joy to live in. Our homes enrich the lives of our clients.

Our Services

We offer a range of services including new homes, additions, and remodels. Our new homes and DADUs span a range of architectural styles and have in common our key design principals: connection between inside and outside, floor plans that foster comfort, functionality, and ease of living, and thoughtful attention to beautiful details within the owner's budgets. For additions, our goal is to create an addition that will integrate well with your existing home and site. We consider additions as an opportunity to either enhance the existing style of your home or to transform the house into something very different. When it comes to remodels, we believe that remodeling an existing home is often the most sustainable way to upgrade a home.

Design Process

We approach each project with a holistic mindset by working with you in a collaborative process to explore creative design solutions while staying attentive to your budget and overall goals. We identify potential constructability issues, assemble the appropriate team, and stay involved during the entire construction process, working with contractors who share our attention to detail. From start to finish, we are your designer, advocate, and project coach.
