At Tumble Creek, the architecture feels inseparable from its Pacific Northwest landscape. Stone and timber ground the private cabins in their forest setting, while deep overhangs and framed views provide shelter and a quieter sense of retreat and privacy, all without losing that connection to the outdoors.

The golf course becomes a natural extension of the landscape, while the clubhouse and shared facilities bring the same refined, rustic character of the private cabins into spaces designed for members to gather and connect.

A home doesn’t need massive square footage to feel open and spacious. When vertical volume, natural light paths, and clear sightlines are prioritized, every square foot carries weight and purpose. It is the balance between height, width, and intentional framing that makes a space breathe.

Design is about how naturally one moves through a space, how the light changes throughout the day, and how a space works for the way one lives.

When making design decisions, we pay attention to all those things - the details that turn a floor plan into a place that feels like it belongs to you.

What’s the first thing you notice when you walk into a well-designed space?

A moment with Project Coordinator, Karl Kroner at our Carbondale office. Get to know Karl and his thoughts on the importance of collaboration in a design process.

“What I enjoy most about design is the process of bringing different perspectives together and seeing an idea take shape through collaboration. I’m always looking for ways to create work that feels thoughtful, authentic to its surroundings, and meaningful to the people who experience it” - Karl Kroner

Congratulations to our very own Riley Hritz on becoming a licensed architect!

This is a remarkable achievement and a true testament to Riley’s dedication and commitment to the profession. The path to licensure is no small feat, it requires completing six rigorous exams, each demanding countless hours of preparation and determination. Riley passed all six with flying colors!

At POSS, we strive to foster an environment where our team members are encouraged to learn, grow, challenge themselves, and pursue their professional goals.

Congratulations, Riley! We are incredibly proud of you and excited to see where this next chapter takes you.

This mountain traditional home was transformed into a contemporary mountain retreat, embracing its surroundings through expansive windows and integrated outdoor living spaces.

Upper-level viewing terraces, a sheltered outdoor fireplace, and pool area create deliberate connections between the home and its natural setting. Clean, geometric lines and a palette of organic yet sleek materials mark a striking departure from the home’s traditional past. The result demonstrates the vast stylistic possibilities of a mountain home thoughtfully designed to embrace its setting and the surrounding views.

We love exploring the balance between clean, modern lines and the warmth of natural materials. This bathroom captures that modern organic aesthetic beautifully, pairing an airy, light-filled space with rich wood tones and tactile finishes that create a sense of comfort, depth, and timeless sophistication.

Over the past several weeks, we’ve had the privilege of looking back on five decades of design, sharing memorable projects, behind-the-scenes moments, and the people who have shaped our journey. We hope these stories have offered a glimpse into the history, passion, and values that continue to define POSS today.

We are proud to share that POSS has officially joined the The American Institute of Architects 2030 Commitment.

The AIA 2030 Commitment provides a framework for firms to measure and improve building performance through a data-driven design process, helping reduce operational carbon while continuously advancing the way we design.

For the past 50 years, our work has been guided by the belief that great architecture begins with listening - to the land, our clients, and the communities we serve. Joining the AIA 2030 Commitment is a natural extension of that philosophy and reinforces our dedication to environmental stewardship and creating lasting value for every project.

To learn more about this national initiative that challenges architecture firms to reduce the environmental impact of the buildings they design through measurable performance and continuous improvement, go to: https://www.aia.org/design-excellence/climate-action/zero-carbon/2030-commitment
