Canadian designers Julia Jamrozik and Coryn Kempster have made Breakwater, a concrete sky-blue playground in Jamestown, New York out of repurposed wave breakers.
Breakwater is made from dolosse, heavy prefabricated concrete blocks normally used to prevent coastal erosion, that have been repurposed as a climbing frame.
The four dolosse used for the project were originally intended for use on Lake Erie
Formed of complex geometric shapes, piles of dolosse are positioned along coastlines to form breakwaters ? barriers that protect the land against the impact of waves.
"We love the strange beauty of a dolos' four-pronged form," Jamrozik and Kempster told Dezeen.
"Dolosse are so sculptural and take on a different appearance depending which end rests down and how they're rotated," they added. "They look so particular and specific, yet entirely cryptic if you don't happen to know what they are and what their intended function is." Children can explore the playground in any way that they please
Jamrozik and Kempster salvaged four dolosse that were originally intended for use on Lake Erie in America.
The design duo re-situated the concrete blocks in an urban context, arranging them into a playable sculpture and coating them in sky-blue polyurea, a spray-on non-slip waterproof coating.

The designers were particularly drawn to how large dolosse are.
"Most of the built environment, when it comes to things we're meant to touch and play with, is scaled...
