Wood Design & Building Magazine, vol 25, issue 101
Every issue of Wood Design & Building tells a different story about how wood is shaping contemporary construction. Some editions revolve around a clear theme such as our recent issue on strategic additions and adaptive reuse; others, like this one, reflect the diversity of challenges, innovations, and contexts that define wood construction today. What unites the features in this issue is not a single building type or region, but a shared commitment to thoughtful planning, ingenuity, and execution.
We begin in the mountains of British Columbia, where the Robson Cabin project pushes the limits of planning and coordination. Accessible only by helicopter, the remote alpine site demanded meticulous preparation, high levels of prefabrication, and an unwavering attention to detail. Alongside the technical complexity, the construction crew also contended with less predictable site conditions—including a persistent population of porcupines, whose curiosity added a memorable twist to an already remarkable build.
From there, we turn to one of the most sought-after—and often elusive—topics in the industry: cost. Reliable, project-specific costing data for mass timber buildings remains rare, and cost uncertainty can be a barrier to wider adoption of mass timber construction. This issue features an overview of a new mass timber business case study published by WoodWorks BC, which presents detailed cost, schedule, and design data from three projects. By comparing mass timber systems to conventional construction approaches across three building types, the study offers valuable insight into real-world construction costs, decision-making, and the strategies that can bring mass timber into cost parity.
Our final feature takes us to Trenton, Nova Scotia, for a virtual construction tour of the Pictou County Sports Heritage Hall of Fame, a community-focused project being realized through close collaboration between designers, builders, and trades. The one-storey building brings together panelized engineered wood walls, traditional light wood frame construction, and a central mass timber foyer, showcasing a deliberate “right material in the right place” approach. Built using offsite fabrication and carefully sequenced installation, the project demonstrates how coordination and precision can be leveraged to deliver a refined wood building that balances efficiency, constructability, and architectural expression.
Together, these stories offer a snapshot of a sector defined by creativity, technical rigor, and resilience—whether navigating rugged mountain terrain, unpacking the realities of construction costs, or reimagining how cultural buildings are delivered. We hope they inform, inspire, and perhaps even entertain.

Wood Design & Building Magazine, vol 24, issue 100
Reaching one hundred issues is a milestone worthy of both celebration and reflection. Wood Design & Building, once upon a time called Wood le Bois, began as a modest trade magazine dedicated to showcasing excellence in wood architecture. Over the years we added special features and technical content that helped us grow a loyal readership and community of wood design advocates.
Recently, our cherished print magazine evolved into a digital, multi-media publication. While this transformation involved a small sense of loss for the printed ways of our past, we remain excited by the expanded potential the new format affords, with a reach far wider than we ever imagined at the outset of this journey. So, while the format may have changed, and content options expanded, our purpose has remained remarkably steady. Issue after issue, we have tried to capture not just great buildings, but the innovations, insights, and architectural aspirations that continue to expand wood’s role in contemporary design and construction.
As we look back, there is a sense of gratitude for all that has unfolded across these pages. Past editions captured early explorations in modern timber construction, the resurgence of adaptive reuse, and the steady shift toward high-performance, low-carbon buildings. Today, advances in mass timber systems, hybrid approaches, and industrialized processes are reshaping how buildings come together. Throughout this evolution, wood has been at the center of conversations about sustainability, long-term value, and design expression. The body of work published over the years reflects not only changing technologies but the steady influence of a material with deep cultural and environmental roots.
It is fitting that our 100th issue is also our special awards edition, honouring the winners of the 2025 Wood Design & Building Awards. These celebrated projects are the latest chapter in the architectural story we have been privileged to document for decades. What distinguishes them is not only their accomplishment today, but what they suggest about tomorrow: a more sustainable built environment defined by technical excellence, architectural warmth, and memorable experiences that transcend program or scale.
To everyone who has contributed, read, shared, and championed this publication—thank you. Reaching 100 issues is deeply meaningful, not because of the number alone, but because it represents a sustained conversation within a community that cares about design, innovation, and the future of building. We remain committed to documenting that evolution, and we look forward to continuing the conversation with you, discovering new stories, and celebrating the work yet to come.
