The Guidebook of Design for deconstruction in Light Wood Frame presents a methodology for altering typical light wood frame assemblies so that they can be easily disassembled and the materials of the building can be reused. The province of BC and, more broadly, Canada, has relatively little infrastructure for recycling wood waste. In Vancouver alone, the construction, renovation, and demolition (CRD) sector produces about 1.7 million tonnes of waste per year.1 Of this, an estimated 30-60% is wood waste which is largely discarded in landfills. What little wood that is recycled is generally incinerated for waste-to-energy conversion or shredded for biomass. Deconstructing wood buildings and reusing the salvaged wood for new construction would extend the lifespan of the wood, add value and longevity to a valuable material, reduce GHG emissions and reduce the amount of new resources required for new construction projects. Despite the benefit of re-using wood, there are some barriers to deconstructing typical light wood frame buildings, including the use of irreversible fasteners, adhesives, spray foams, and liquid applied sealants. The presence of toxic materials such as asbestos and lead are also of concern when deconstructing a building. While use of toxic materials is now prohibited in new constructions the use of nails (particularly when applied with nail guns) and adhesives makes deconstruction very difficult if not impossible in some cases.2 This guidebook proposes a design for deconstruction system that addresses these remaining issues with simple modifications of typical light wood frame construction practices, allowing for both simple construction, solid performance, and easy deconstruction.
Buildings that stand the test of time aren’t just durable—they are cherished. When we invest in quality materials and good design, we can create buildings that people connect with. As you’ll discover in this issue, many heavy timber warehouses and factories constructed in the early 1900s remain a vital part of our cities today—not because they still serve their original purpose, but because people valued them enough to adapt, restore, and reuse them, giving them a new purpose.
Fast forward a hundred years and resilient structures include many new forms. Modular construction, for example, has seen significant growth in recent years as this form of construction has transformed from a building method once considered inferior, into a method relied upon to deliver high-performance durable buildings.
Alongside our features on historic timber buildings and modular construction, this issue also highlights notable projects and emerging trends shaping today’s built environment. From innovative mass timber structures to forward-thinking design solutions, we explore how thoughtful craftsmanship and smart engineering continue to define the spaces we build—and the ones we keep.

Some engineered wood panel products, such as plywood and laminated veneer lumber (LVL) are able to be treated after manufacture with preservative solutions, whereas thin strand based products (OSB, OSL) and small particulate and fibre-based panels (particleboard, MDF) are not. The preservatives must be added to the wood elements before they are bonded together, either as a spray on, mist or powder.
Products such as OSB are manufactured from small, thin strands of wood. Powdered preservatives can be mixed in with the strands and resins during the blending process just prior to mat forming and pressing. Zinc borate is commonly used in this application. By adding preservatives to the manufacturing process it’s possible to obtain uniform treatment throughout the thickness of the product.
In North America, plywood is normally protected against decay and termites by pressure treatment processes. However, in other parts of the world insecticides are often formulated with adhesives to protect plywood against termites.
