Abstract
The Kathmandu Valley is confronting escalating urban challenges driven by rapid population growth and unchecked concretization. In an earthquake-prone context, the dominance of reinforced concrete has raised critical concerns over seismic safety, environmental degradation, and long-term ustainability. Addressing these challenges calls for rethinking material choices that balance resilience, ecological responsibility, and cultural continuity. Timber, deeply embedded in the Kathmandu Valley’s architectural heritage, offers such potential. Global advances in engineered wood, particularly cross-laminated timber (CLT) have positioned timber as a sustainable alternative to conventional construction. With its strength-to-weight efficiency, carbon sequestration capacity, and proven seismic performance, CLT is gaining momentum worldwide. Yet, its feasibility in Kathmandu depends not only on technical adaptation but also on stakeholder acceptance. This study examines the social feasibility of CLT adoption in the Valley. A qualitative approach, based on semi-structured interviews with architects, engineers, contractors, policymakers, teachers, and local residents, was employed to capture perceptions, opportunities, and reservations. Findings reveal broadly favorable views of CLT’s environmental and seismic benefits, alongside recognition of its role in reducing concrete dependency in coming years. However, significant concerns remain particularly around cost, fire resistance, supply chain limitations, and the absence of local expertise. The study concludes that CLT presents a promising pathway for sustainable and resilient construction in Kathmandu. Realizing this potential requires targeted policy frameworks, demonstration projects, and technical capacity-building. Positioned at the intersection of tradition and innovation, CLT could enable the Valley to reimagine its built environment in ways that honor heritage while addressing urgent urban challenges.
