Wood Design & Building Magazine, vol 25, issue 102
This issue of Wood Design & Building explores how intentional design can carry culture, support community, and foster connection. The projects featured here demonstrate how a clear vision can transform a building into an environment grounded in purpose, identity, and care, reflecting both people and place.
Several projects in this issue centre Indigenous perspectives and priorities. The Membertou First Nation office building, the Weliankweyasimk Women’s Shelter, and the Chief Leonard George residential building each reflect cultural knowledge, respond to community needs, and create spaces of safety, continuity, and belonging.
Wood is a consistent presence throughout. Long associated with shelter and refuge, it is also a material of gathering, warmth, and shared experience. It is no coincidence that projects grounded in human wellbeing so often turn to wood. This connection is present in many cultures. Our WoodWare feature on FinnFox, for example, highlights the part wooden saunas play supporting health and building community in Nordic (and Canadian) sauna culture.
At the same time, building with wood is not simply a return to the past. While it reconnects us with cultural knowledge and longstanding practices, it also reflects a growing recognition of wood as a high-performance, renewable material for contemporary construction. This is evident in the Chief Leonard George Building, Canada’s first tall mass timber residential building constructed to the Passive House standard. It demonstrates how thoughtful wood design can both preserve cultural continuity and point toward the future of high-performance, low-carbon construction.

Scaling Affordable Rental Housing with Tall Mass Timber
Course Overview
As cities face growing pressures around affordability, climate resilience and livability, innovative projects like Catalyst’s 18-storey CLT rental development in North Vancouver offer necessary solutions. Targeted toward architects, engineers, developers and municipal leaders this session explores mass timber construction as an affordable housing solution. Attendees will gain insight into the use of CLT in construction and the associated challenges, including structural grid constraints, moisture protection, and prefabricated balcony systems. The session will also highlight how the project achieved near cost parity with comparable concrete buildings, integrated mixed-use programming, and leveraged BIM to support coordination and the permitting process. Participants will leave with practical takeaways for applying these approaches to similar projects in other cities.
Learning Objectives
Understand how tall mass timber hybrid systems can support affordable and mixed-use housing
Identify key architectural, structural, and construction challenges unique to CLT buildings
Learn practical strategies for permitting, procurement, coordination, and construction

Unlocking Affordable Timber Innovations in Structure, Prefabrication, and Code
Course Overview
Bond Tower is a 7-storey mixed-use prototype that asks a critical question: how can mass timber be made cost-effective in the Prairies, where supply chains are limited, demand is low, and timber construction is often reserved for flagship projects. Funded by the Green Construction through Wood Program from Natural Resources Canada, the project develops both prototypes and a built demonstration to advance affordable timber solutions in a region underserved by the current market.
The design leverages nail-laminated timber (NLT) as its primary system, applied in diagrid trusses, floor assemblies, and shear walls. NLT presents a cost-effective alternative to other manufactured products and provides great versatility due to its custom nature. Lateral and gravity-induced forces are carried by a diagrid timber truss fabricated from readily available dimensional lumber and using simple mechanical fasteners. Floor assemblies comprised of NLT are constructed without a concrete topping or proprietary sound attenuation systems, reducing both cost and embodied carbon. Prefabricated wall panels, stairs, and modular service pods further minimize waste and construction time.
Another challenge lies in building code classification. Currently, all structures above six storeys are deemed high-rise, requiring costly and difficult to achieve [in timber] two-hour fire-resistance ratings and fire-safety systems. The Bond Tower design team, working with code consultants, is developing an alternative solution that leverages the inherent 1.25-hour FRR of NLT floor assemblies. This approach suggests a pathway toward a new mid-rise category, making timber projects of seven or eight storeys more financially viable. Alongside a single-stair configuration, which can increase efficiency by reducing non-rentable floor area, these strategies point to a replicable model for affordable timber construction across Canada.
Learning Objectives
Learn how NLT and prefabrication strategies can reduce cost, waste, and construction time, making timber more feasible in the Prairies.
Explore structural detailing approaches that simplify connections and reduce cost, while addressing fire, durability, and acoustic performance in timber design.
Examine how alternative solutions can improve the financial feasibility of 6–8 storey timber projects and support broader code updates across Canada.

Guide to Mid-Rise Wood Construction in the Ontario Building Code
Second Edition
Applicable to the 2024 OBC (O. Reg. 163/24) – In Effect January 1, 2025
Overview
The Guide to Mid-Rise Wood Construction in the Ontario Building Code (Second Edition) provides a technical overview of the provisions permitting 5- and 6-storey combustible (wood) construction under the 2024 Ontario Building Code.
Developed by WoodWorks Ontario / the Canadian Wood Council, this updated edition reflects O. Reg. 163/24 and recent amendments affecting mid-rise residential (Group C) and office (Group D) buildings.
The Guide identifies key requirements, conditions, and limitations associated with mid-rise wood construction and is intended to support architects, engineers, builders, regulators, and code professionals working in Ontario.
What’s Included
This technical reference outlines:
Height and building area limits for 5- and 6-storey wood buildings
Fire-resistance requirements for floors, roofs, mezzanines, and loadbearing assemblies
Sprinkler system requirements (NFPA 13 vs. 13R)
Combustible cladding limitations and compliance pathways
Fire blocking and concealed space requirements
Fire department access and street-facing provisions
Emergency power enhancements
Structural and seismic design considerations
Mixed-use building permissions and occupancy separation requirements
The Guide focuses on new construction and is intended to be used in conjunction with the Ontario Building Code.
Developed to support practitioners working with encapsulated mass timber construction (EMTC), this tool helps determine whether a compartment design aligns with the 2025 edition of the National Building Code of Canada (NBC).
By entering key information about your compartment layout—including size, wall configuration, mass timber elements, and encapsulation details—the calculator evaluates whether the design meets code requirements for exposed mass timber elements.
The tool allows users to:
Evaluate permissible percentages of exposed mass timber elements (beams, columns, walls, and ceilings)
Confirm compliance within suites or fire compartments
Identify potential code issues through automated warnings
Visualize compartment configurations with a generated 3-D model
Review encapsulation requirements and supporting notes
This practical calculator helps architects, engineers, and code professionals explore compliant design options more efficiently when working with mass timber construction.
