Utilising mass timber to unlock the potential of adaptive reuse projects for subsidised human settlements

Abstract

This mini-dissertation explores the transformative potential of mass timber (MT) in adaptive reuse (AR) projects to address South Africa’s housing crisis in Pretoria's Central Business District (CBD). The research examines perceptions and experiences of construction professionals—engineers, architects, quantity surveyors, and construction managers—regarding MT and AR through detailed questionnaires and interviews. By leveraging the inherent strengths of MT, such as its sustainability, strength, lightweight properties, and rapid construction capabilities, this study aims to present MT as a viable solution to overcome the challenges of AR projects. The literature review investigates the pressing need for centralised social housing, highlighting the potential of repurposing obsolete buildings in the Pretoria CBD for low-income housing as part of urban renewal strategies. The study also addresses the complexities and benefits of AR, proposing strategies to revitalise dormant structures and integrate MT to create sustainable, efficient, and socially inclusive urban environments. Key findings indicate that MT facilitates faster construction, reduces environmental impact, and allows vertical extensions of additional stories in high-density urban areas. Despite some challenges, such as the initial cost and limited awareness among industry professionals, the successful implementation of MT in AR projects can significantly contribute to meeting the demand for centralised social housing. The study concludes that strategic collaboration, financial incentives, education initiatives, and industry guidelines are essential to overcoming barriers and promoting the widespread adoption of MT in AR projects.
