Urban Regeneration Through Retrofit: Adaptive Reuse of Underutilized Commercial Buildings as Mixed-Use, Diverse and Amenity-Rich Developments

Behavioral shifts caused by the pandemic have lingered even today. Increased hybrid work and accelerated migration out of cities are creating unique opportunities for city planners to redesign cities and meet today’s demands. Mixed-use and integrated 20-minute work, live, and play communities have proven to survive the test of time.

Recent reports from Cushman & Wakefield , Savills and others claim over 20% of office spaces in Europe and North America were vacant in 2024, resulting in pilot rezoning programs to revitalize city centers. High vacancy results in lowered asset value, and thus a decrease in tax revenue from commercial property. This is having a cascading impact on local councils to upgrade and maintain civil amenities in communities and public safety—city planners are piloting rezoning programs to address this and revitalize city centers. In Europe, underutilized office buildings are being converted into student accommodation to relieve housing shortages. London’s famous landmark, the Old War Office building has been redeveloped into luxury flats and a hotel complex with recreational facilities.

On the other hand, low footfalls in malls and high streets are pressing developers to rethink retail space; for instance, Rhode Island’s historic Arcade is being reborn as 48 micro apartments to meet local housing demands. Over the next few years, retail spaces are evolving to experience centers or spaces intended for delivery and logistics fulfillment, rather than traditional retail.

Realities on the ground are far more complex; offices and malls are typically designed with deep floorplates and a lack of natural light—a key concern for residential units. While perceived as a shortcut for developers to deliver projects within 18 to 24 months through expedited permits, pressing challenges include structural adaptions, cost, hazardous materials, historic preservation regulations, and nuances to upgrade aging utilities. Planning rights are evolving with time, allowing developers to convert single-use commercial buildings into mixed-use amenity-rich hubs for the community. Authorities need to enforce spatial & indoor quality standards, health & wellbeing on brownfield retrofits, and wider compliance, ensuring redeveloped spaces are code compliant.

ABI Research’s recent report forecasts that mixed-used commercial buildings will have the highest Compound Annual Growth Rate (CAGR) of over 16% during the next few years, with mixed typologies making up to 50% of residential area. For office and retail buildings to survive turbulent times, building developers are adapting briefs to prioritize diversity, adaptability, and flexibility in function on a building and floor level, rather than homogeneity of use.

Developers are tapping into the following strategies to stay competitive: 

• Office spaces are competing with our homes, leading to the “hotelification” of office spaces with a mix of formal and informal working environments versus pure traditional work environments with connectivity becoming a given.
• Digital tools for spatial management, hot desking, and mapping occupancy solutions like deskbird, Freespace, OfficeSpace, and Tactic support different degrees of collaborative and individual work to support hybrid work.
• Integrating smart technology for lighting and Heating, Ventilation, and Air Conditioning (HVAC) support personalized work environments for occupants, and further support facility managers to track usage patterns to optimized building operations by reducing carbon footprint.
• Amazon, Citigroup, Walmart, and UPS are enticing workers through amenity-rich spaces, prioritizing health & wellbeing like massage rooms, healthcare services, and on-site personal gyms to help recruit and retain new talent.
• In Europe, premium low-carbon and sustainable office spaces are in high demand with high occupancy as companies prioritize low-carbon operations, implementation of energy efficiency measures, and green building certified spaces with proven lower operational cost.
• Lastly, on a floor level, spaces and furniture are designed with modular configurations catering to multi-functionality for resilience.

Thus, hybrid adaptable buildings are becoming more advantageous to developers with rentals charged at a premium and short leases to accommodate changing spatial usage.
