Adaptive Reuse and the Heritage Construction Workforce: A Practitioner Informed Analysis of Sustainable Urban Regeneration

Abstract

Adaptive reuse, the repurposing of existing buildings for new functions, is widely promoted as a strategy for sustainable urban regeneration, yet the practice faces persistent obstacles relating to retrofit cost, gentrification risk, and a heritage construction workforce that is ageing, under trained, and poorly served by existing career pathways. This study combines a systematic review of the adaptive reuse and heritage retrofit literature with two complementary qualitative strands: informal practitioner interviews and site observations within the heritage construction sector, and a netnographic thematic analysis of publicly available, anonymised discourse drawn from architecture and urban planning online communities concerning adaptive reuse practice and career entry. The study is underpinned by an integrated theoretical framework combining Circular Economy theory (Ellen MacArthur Foundation, 2013), Rogers' (2003) Diffusion of Innovation theory, and Human Capital Theory (Becker, 1964), used respectively to interpret adaptive reuse as a materials and value retention strategy, to explain uneven adoption of reuse over demolition, and to frame the workforce development obstacles identified in the sector. Thematic analysis of the combined practitioner and discourse corpus produced six themes: the material and regulatory friction of retrofit relative to new build; contested and highly subjective criteria for what counts as worth preserving; gentrification and displacement as an underexamined cost of regeneration; the absence of formal, accessible training pathways into heritage construction; non-standard, non-linear career entry routes as both an opportunity and a source of market uncertainty; and adaptive reuse as a genuine, if precarious, professional niche. These findings substantiate and extend the practitioner-derived conclusions of the original fieldwork, indicating strong convergence between formal literature, direct practitioner testimony, and independent online discourse regarding both the sustainability case for adaptive reuse and the structural weaknesses of the workforce pipeline that services it. The paper concludes with a revised conceptual model and policy and industry recommendations addressing training accessibility, career pathway formalisation, and gentrification mitigation.
