LOO GARDENS

Brief

Tideway had completed its landmark Super Sewer — a project designed to reconnect London with the River Thames. By intercepting 95% of untreated sewage overflows, the sewer would dramatically improve water quality and restore the river’s ecosystem. In the midst of negative press about river pollution, Tideway needed a bold, positive way to celebrate this environmental milestone.

Solution

We created the UK’s first underground botanical garden, located 50 metres beneath London — filled with the very plants and wildlife expected to return to the Thames thanks to the Tideway tunnel.

The immersive installation featured:

  • Native Thames-side flora and underwater-inspired planting

  • A bespoke natural soundscape by a composer who had worked with Kew Gardens

  • Scented wetlands aromas designed by London perfumers

  • Sculptural plant life made from waste materials dredged from the river

  • All materials were recycled after the event. 

To ensure wide public engagement, we partnered with Time Out to
run a competition, giving Londoners a rare chance to explore the
garden firsthand.
