EPR Architects' net zero carbon London studio, All Saints, is a retrofit project that epitomises the values of the practice with innovation, flexibility and sustainability at its core.

All Saints is an exemplar of sustainable refurbishment.

The use of embodied carbon was monitored and kept to a minimum through informed design choices, with new materials introduced to the building selected for their low carbon content.

Existing features were sensitively reused wherever possible and poor-performing existing building elements were upgraded with new thermally efficient alternatives. This, combined with mixed-mode ventilation that allows passive cooling and an all-electric heating/cooling system, enables the building to be Net Zero Carbon in operation.
