“Beauty is the harmony of purpose and form”.
– Alvar Aalto

This notion succinctly expresses our design philosophy, whether considering traditional or modern architecture. Inspired by this notion of architectural beauty in architecture we add our experience by:

  • Helping our clients see all the potential of their site and living space, whether it’s new construction or an extensive remodel.
  • Providing expertise and support throughout every project, informed by decades of experience.
  • Infusing each client’s vision into beautiful solutions designed to foster living well.

These practices build a lasting relationship, one based on personal connection and trust, through careful listening and thoughtful questions. What are your needs and desires? How do you want to live, both today and years from now? What is your budget?

With KSA, inquiry, curiosity, and discussion illuminate a unique path toward insightful design that accommodates delightful living and enduring value. Your living environment can reward you with delight every day.

Kevin has guided his clients to find the best paths for more than 30 years, creating a diverse collection of beautiful, enjoyable homes and vacation homes across Seattle, the Puget Sound region and beyond.

"Kevin, we cannot put into words how pleased we are with you and your team. Your design lifted our dated kitchen and dining room out of the 1990’s and provided us with a beautiful, functional, and modern living space. You listened to our needs and worked seamlessly with our contractor to tweak and adjust the design each step of the way. And the process was all surprisingly painless! We hope to work together again and highly recommend your firm.” Note: This client is currently engaged in their second project with Kevin."
"Kevin Spence worked very closely with us to design our new kitchen, bathroom, and lower level of our home. The design challenge, to a lay person, was a bit tricky. It involved moving a staircase to open up space in living areas of our home. Kevin was very responsive to our needs throughout the entirety of the project. It was a pleasure to work with him. The result of Kevin's work is nothing short of spectacular. We now have totally functional, beautiful, and living-friendly space, thanks to his designs."

Kevin's Story

When Kevin was 11 years old, his parents hired an architect. Kevin enthusiastically watched his family’s home emerge from hopes and ideas into reality. He experienced the inspiring interplay of land, design, and lifestyle in the custom house that fulfilled his family’s changing needs for decades. All appreciated how beauty arose from the way the house nestled in the terraced avocado grove to the fine materials and details throughout the interiors.
