In this Forbes article, Jennifer Castenson argues that design for disassembly (DfD) could address both construction waste and housing supply shortages by changing how buildings are conceived and built. Traditional demolition sends enormous volumes of material to landfills, reflecting a linear take-make-dispose model that casts out valuable components. By contrast, DfD anticipates a building’s eventual end of life and engineers structures so that major parts can be taken apart and reused or recycled. Adopting this approach could retain value in building materials and reduce the environmental and economic costs of construction.
Castenson points to efforts by companies such as Panasonic to embed disassembly-friendly principles into products and building systems. These initiatives reflect growing interest in circular practices that extend beyond recycling to designing out waste from the start. Buildings planned for future disassembly would use connections and components that are easy to detach, sort, and repurpose, transforming what is now waste into reusable inventory for future projects.
The article suggests that widespread adoption of DfD could future-proof housing markets by making materials more readily available, lowering raw material costs, and smoothing supply bottlenecks. Such reuse pathways can also diminish pressure on new resource extraction and lower carbon emissions tied to manufacturing new building products. However, this shift requires more than new design manuals. It depends on supportive regulation, supply chains that can handle reclaimed components, and economic incentives that make reuse competitive with new construction.
The article situates DfD within broader sustainability trends. It aligns with circular-economy principles that prioritize reuse and resource longevity over short-term throughput. If the construction industry, regulators, and policymakers embrace disassembly-oriented design, the built environment could become significantly more efficient, less wasteful, and more resilient in the face of housing demand.
