We’re presenting a new type of children’s play structures, for both aquatic and dry playground areas, based on a solid known since ancient times: the tetrakaidecahedron, or Kelvin polyhedron.
Formed by 8 hexagons and 6 squares, it was described by Archimedes more than two millennia ago. Its usual name is owed to Lord Kelvin, who in 1889 demonstrated that it is the only semi-irregular solid that can fill space by repeating itself.
Using different polyhedron deformations, with Kelvin City we propose joining these hollow shapes, in order to circulate through their interior and access play elements and transit at different heights.
Users climb and access bridges and walkways from platforms that lead to slides and other play features, with original and eye-catching results.
