Embodied carbon

Efficient

Embodied carbon strategies

  • While no formal certification such as LEED, BREEAM, or DGNB has yet been pursued, the design was guided by the ISO 20887:2020 standard for adaptability and disassembly. This framework ensured that considerations for embodied carbon reduction and resource efficiency were embedded from the project’s earliest stages.
  • Embodied carbon was also addressed through minimised excavation — with parking limited to two basement levels instead of full substructure development — which preserved natural soil strata and reduced the overall structural mass. 
  • In addition, off-cuts from Equitone cladding panels were reused within interior finishes, turning potential waste into functional design features and further reducing material consumption.
  • Although no formal embodied carbon assessment has yet been published, the project’s approach demonstrates a consistent emphasis on material efficiency and waste minimisation.

Operational Emissions / Energy

Low Carbon

Operational emissions strategies

  • Lake 11 Home & Park is entirely powered by a geothermal heat pump system that provides both heating and cooling across the development. The system replaces fossil fuel dependence, achieving long-term energy efficiency and ensuring a renewable, closed-loop energy cycle.
  • According to project figures, the geothermal installation reduces heating and cooling energy demand by around 30 percent compared with conventional systems. Additional strategies — including green roofs, semi-intensive and extensive planting, and biodiverse landscaping — regulate the microclimate, reduce heat gain, and improve on-site stormwater retention.
  • Together, these measures contribute to a significant reduction in operational energy consumption and associated emissions.

Afterlife

Adaptive Reuse and Flexible Design Considerations

Adaptability was a central principle throughout the design process, ensuring the buildings can accommodate evolving uses and needs over time. Apartments feature flexible layouts with interchangeable service and storage zones, allowing units to be combined, subdivided, or reconfigured for different living arrangements. 

Ground-floor connectors were designed as multi-functional spaces that can host cafes, co-working areas, or local shops depending on community demand. This built-in flexibility supports long-term adaptability, extending the life of the buildings and their relevance within the neighbourhood.

Disassemblable Elements for Circular Economy

The project was guided by the ISO 20887:2020 standard for adaptability and disassembly, embedding circular thinking from the outset. Key building elements and material systems were planned for ease of maintenance, replacement, and eventual reuse. The facades, for example, employ a modular cladding system whose panels can be removed or repurposed, and off-cuts from the Equitone cladding were already reintegrated within the interiors. This approach reduces waste during both construction and future renovation, ensuring that major components can enter the circular economy rather than becoming demolition waste.
