McLennan Design, Perkins&Will’s Bainbridge Island studio, is an architecture, planning, and consulting firm, founded by Jason F. McLennan, creator of the Living Building Challenge. We imagine regenerative buildings, places, and products that give back—spaces that nurture people, connect communities, and enhance life in places.
Acts of Regeneration
Rooted in regeneration—where people, place, and purpose come first. From adaptive reuse of existing buildings, residences, cultural institutions, innovative corporate headquarters, urban planning, to climate-positive campuses, and product design our work proves that beauty, performance, and ecological intelligence can coexist—and thrive.

Sports & Sustainability
This issue explores the intersection of sports and design, highlighting standout Perkins&Will athletic projects such as Northeastern University’s Multipurpose Athletic Facility. It also reflects on the Climate Pledge and the creation of the GOAL system, a framework for the continuous improvement of sports environments. Alongside these features are thoughtful contributions from our team, including Josh Fisher’s exploration of his passion for skating and Johanna Collins’ application of biomimicry in practice. On a lighter note, the issue concludes with a short personal piece, “My Life in Gastronomy,” offering a more reflective look at food and experience.

Our Regenerative Ethos
The way we see it, design is the opportunity to imagine—and build—a better tomorrow.
Every project is a chance to strengthen the places we call home. We begin by listening—to the land, the community, and the cultural and ecological stories that shape each site.
Regenerative design is our operating principle, linking performance, ecology, and human well-being. Through rigorous research, systems thinking, and collaborative engagement, we turn bold ideas into spaces that are beautiful, resilient, and measurably impactful.
