Founded in 1991, KSI Architecture & Planning has evolved more than most. A California native, owner William Strouse has been watching KSI morph for over 30 years; from a 20+ office in Pioneer Square to a 4-person dream-team in the Industrial District, we understand the importance of versatility and adaptability.
For this reason, we want to be the most approachable know-it-alls you can find. We avoid specializing in one area in order to do it all- we’ve designed an especially nice closet for a very organized Seattleite and a 700,000 sq. ft. industrial building in Oklahoma. We’re passionate about the built environment, and our ultimate goal is to create a building (or a closet) that speaks appropriately to the natural environment it sits in and the people it will serve.
Now a proud family-run show, creating personal relationships with our clients has become one of our most important priorities. We find great value in truly understanding who we’re designing for. Your morning coffee, family dinners, or conference room meetings are the most important part of our job, and we promise to never forget that.
With a love for natural light and creating the most seamless of indoor-outdoor relationships, our dream is to get you excited about your dream. Give us a call, shoot us an email, or come by and check out our Seattle studio in Sodo!
