The Queen Elizabeth II Garden in Regent’s Park repurposes 1,000 cubic metres of crushed concrete from the demolished QEII venue into a living high-pH landscape.
Key Takeaways
1,000 cubic metres of crushed concrete were reused on-site, eliminating significant demolition-waste transport and landfill cost.
Crushed concrete raises soil alkalinity sharply, ruling out most ornamental plants and requiring deliberately alkali-tolerant, hardy species.
The design treats material constraints as the brief: plant palette and layout were determined by what the rubble substrate would actually support.
Patience is load-bearing in the concept; the garden is designed to mature slowly, not arrive finished at opening day.
“Built from its own ruins” is the framing: circular material reuse as identity, not just a sustainability checkbox.
