Over the past four years, we have collaborated with scientists at the Natural History Museum and art preservationists Factum Arte to design and make the world’s first and only post-tensioned bronze dinosaur.

Based on the Museum's much-loved Diplodocus cast, the new attraction is a free-standing, 25m long, life-size bronze dinosaur. Newly named Fern, it was officially unveiled in July 2024 in the revamped museum gardens as part of the Urban Nature Project.

Fern was one of the most technically complex challenges we have undertaken, and the design required months of problem solving and the creative contribution of numerous academics, technicians and craftspeople to develop the engineering solution.
