Resilient London: confronting climate change

Resilient London: confronting climate change

33 King William Street is a new landmark office development situated on a
prominent site in the City of London. Existing elements of the site were extensively
reused, all 160 piles, the reinforced concrete raft slab and drainage system were
salvaged whilst increasing the area of office space by 65 per cent. Sustainably
manufactured new materials were also specified that at end of use can be recycled,
for instance the natural terracotta faience cladding. The terrace features high
performance photovoltaics which are particularly effective on an island site. All
furniture uses FSC timber and the planting was selected to create a biodiverse
environment with native wildflowers encouraging bees and insects.
