Dubbed 'See Monster', the former North Sea platform now features four publicly accessible levels that play host to a wild garden of plants, grasses and trees.
The installation also includes an amphitheatre, a multi-level slide, a 6,000-piece kinetic installation forming the monster’s 'scales' and a 10-metre waterfall. At the base of the 35-metre-tall structure is a broadcast studio.
Those behind the project are hoping it will transform perceptions around how out-of-date industrial infrastructure is disposed of.
The project was the brainchild of Leeds-based design and events company Newsubstance and forms part of the 'Unboxed: Creativity in the UK' festival.
