Better design could transform new homes for a changing climate

As climate pressures intensify, experts say new homes must be reimagined from the ground up. Current building designs are increasingly ill-suited to withstand extreme weather events, rising temperatures, and energy demands, prompting calls for a fundamental shift in how houses are planned and constructed.

Rethinking the basics of building design
Traditional construction often prioritises aesthetics or cost efficiency over resilience and environmental performance. Architects and engineers now argue that orientation, insulation, natural ventilation, and sustainable materials must form the foundation of new homes. Integrating these elements can reduce energy consumption, lower carbon footprints, and improve occupant comfort.

Passive design and energy efficiency
Passive design strategies, such as maximising sunlight in winter and shade in summer, incorporating thermal mass, and improving airtightness, can significantly reduce heating and cooling needs. Experts note that homes built with these principles perform better in extreme conditions while lowering utility bills for occupants.

Adapting to local climates
Design solutions must be tailored to local conditions. Coastal areas may need elevated foundations to address flood risks, while urban centres could benefit from green roofs and reflective materials to mitigate heat island effects. Climate-adapted planning ensures homes remain safe, comfortable, and cost-effective over their lifetimes.

Policy and industry collaboration
Governments and the construction industry are being urged to adopt updated building codes and incentives that reward climate-conscious design. Collaboration between architects, planners, and policymakers can accelerate the transition toward resilient and sustainable housing that meets the challenges of a warming planet.

The way forward
Experts emphasise that better design is not optional but essential. By embedding climate resilience and sustainability into the core of new homes, society can mitigate environmental impacts, protect residents, and create long-term value in the housing sector.
