Resilient London: confronting climate change

Resilient London: confronting climate change

Holbein Gardens transform an outdated office into an exemplary zero carbon
workspace. Adding an additional floor to the retained four-storey structure, as well
as reusing materials and introducing extensive greening, results in 25,000 sq ft of
high-quality flexible workspace. The project will provide an all-electric building with
biodiversity at its heart and a range of innovative materials and technology. The design
has a 69 per cent operational carbon saving against a typical office building. Facade
retention will save 39 per cent embodied carbon compared to a new facade solution.
Furthermore, an all-electric clean energy supply enables the scheme to be net zero
carbon by 2030, and 99.95 per cent of strip out waste has been diverted from landfill.
