Integrity is the foundation of our practice, guiding a client-centered process and a commitment to timeless design. Our designs honor its purpose, its people, and its place - now and for generations ahead.

At POSS, design is more than form-it’s a philosophy. For fifty years, we’ve embraced the challenge of creating architecture and interiors that honor their surroundings while pushing the boundaries of what’s possible. Every space we shape is grounded in purpose, enriched by craft, and guided by a belief that beauty and function should endure in equal measure.
