Bartlett Professor Synthesises Soil and Robotics at the Royal Chelsea Flower Show

21 May 2019

Professor Marjan Colletti has co-designed a biodegradable 3D-printed structure, Terrestrial Reef, for the Royal Horticultural Society’s flagship event, taking place this week.

Terrestrial Reef by Marjan Colletti and Tiziano Derme

A unique hybrid of natural and synthetic elements, Terrestrial Reef examines the implications and opportunities of a fictional future scenario, where landscape is designed and shaped by artificial intelligence, asking the question: ‘how would machines develop a hybrid ecosystem of natural and artificial symbionts?’. The project is co-designed by Tiziano Derme from University of Innsbruck and MAEID.

Terrestrial Reef is the second project working to an ‘anti-garden’ concept, developed initially with Pahoehoe Beauty for the 2018 Ars Electronica Festival in Linz. It will be displayed within the Show Garden Silver Medal Winner ‘Gardening Will Save the World – Ikea and Tom Dixon’ pavilion, at the 2019 RHS Royal Chelsea Flower Show until Saturday 25 May.
