Sustainability

The practice works to sustainability targets on every commission, seeking to produce buildings that actively reduce carbon use.

Whole-life costing, fabric performance, passive design and low-carbon servicing strategies are embedded in our designs rather than added at the end. Our directors write and speak regularly on architectural sustainability.

Retrofit and reuse are central to this: the most sustainable building is often the one that already exists, and our conservation and surveying teams work alongside our architects to extend the useful life of existing fabric.

What we do

  • Whole-life costing
  • Fabric-first and passive design
  • Retrofit and adaptive reuse
  • Low-carbon servicing strategies
  • Post-occupancy review
  • Sustainability reporting
