Adaptive Reuse
Spanning buildings, infrastructure, and landscape, the concept of adaptive reuse has gained prominence as a versatile strategy for sustainable urban transformation. Rather than demolishing outdated assets, these projects demonstrate the manifold benefits of harnessing the embedded value in existing structures. Through sensitive reprogramming, they have revitalised city fabric, contributed to new mixed-tenure housing provision, catalysed vibrant public spaces, and preserved local heritage. In order to achieve these benefits, these projects must often navigate regulatory and zoning frameworks, secure finance for innovative projects, and reconcile heritage with contemporary performance standards. The long development timelines for such transformations further attests to the complexity of adaptive reuse, yet their social, cultural, and environmental potential can be substantial.

Efficiency & Emissions
Urban retrofit as a vehicle for emissions reduction aims to achieve tangible results through best-in-class building retrofits and ambitious citywide plans. Project outcomes are supported by strategies such as Passive House standards, context-specific low-carbon policies, and creative use of levies and incentives.
However, the widespread delivery of these interventions faces significant hurdles, including financing retrofits at scale, bridging skills gaps among trades and design professionals, and minimising disruption for occupants. Despite these challenges, the evidence suggests that efficiency-led retrofit projects have enormous potential to transform urban decarbonisation, provided policy, finance, and delivery mechanisms work together effectively.

Affordable Housing Delivery
The delivery of genuinely affordable, secure, and socially supportive housing has emerged as a defining challenge across the urban retrofit landscape. Successful models range from large-scale, master-planned, mixed-tenure neighbourhoods to community-led, cooperative, and mixed-governance approaches, including notable “zero-relocation” models that avoid tenant displacement.
To be successful, these schemes must contend with structural barriers, including reliance on subsidies and short-term funding cycles, delays associated with larger planning schemes, tensions between market and affordable delivery, and the threats of gentrification and displacement. The complexity of coordination between agencies, developers, and community actors further complicates delivery, yet these examples offer a robust playbook for cities determined to address their housing crises while advancing broader objectives of equity and inclusion.

Montréal, Canada

Human-Centred Retrofit
Case studies from across the Canadian Study Tour consistently challenged the notion that technical retrofit alone will produce lasting, sustainable retrofit outcomes. Human-centred retrofits are those which emphasise the social processes, such as community organising, behavioural change, and empowerment, that ultimately anchor physical improvements. Initiatives range from green alley stewardship and youth engagement programmes to participatory forums fostering environmental awareness.
Notably, these interventions demonstrate that tenant and resident practices are often as decisive as equipment upgrades in achieving energy and cost savings. Scaling human-centred retrofits also presents significant challenges, including cultural and awareness differences, volunteer and professional fatigue, resistance to disruption, and the need for tailored training pathways.
