World Play Day is June 11. To commemorate, the Serpentine Galleries and LEGO Group are working with Archigram’s Peter Cook to deliver a Play Pavilion in London’s Kensington Gardens. Bettina Korek, Serpentine Gallery CEO, and artistic director Hans Ulrich Obrist are working with Cook on the venture. The Play Pavilion will be built in Serpentine South out of LEGO® Bricks, the design team said. Cook’s design will mingle near the 2025 Serpentine Pavilion by Marina Tabassum Architects, A Capsule in Time, aligned with Serpentine South’s iconic bell tower. Cook, in a statement, called Play Pavilion “a piece of theatre.” Visuals reveal Play Pavilion as topped by a geodesic dome of sorts that recalls past structures by Buckminster Fuller. Beneath the domed roof will be a semi-enclosed space encircled by polychromatic, jagged planes awash with colors that evoke the plastic toys. “From a distance, intriguing shapes rise from within the structure, although partly obscured,” Cook said in describing the design. “Activities inside can be viewed through pierced and scooped walls, as if teasing ‘come closer, there’s more.’ A child might pop out on a slide, another may crawl through a hole on the ground, mystifying conventional entrance routes.” Cook added: “Another mouth-shaped opening reveals an orator, performer, or singer entertaining eavesdroppers beyond.” In a joint statement, Korek and Obrist noted that Play Pavilion marks a major milestone. Before her death, Zaha Hadid envisioned a project between Cook and the Serpentine, the pair said. “Hadid’s legacy will be fittingly honored through this project, which reflects her pioneering spirit and relentless pursuit of innovation.” “Play transcends survival, achievement, and common sense,” Cook continued.  “It encourages, or at least permits us, to explore and idly delight in a territory between the wayward and the speculative towards unashamed amusement.” The temporary structure will touch down in the location other past works have been installed, including STRIP-TOWER by Gerhard Richter. The Play Pavilion will host public programming through August 10. The Royal Parks and CONSUL are also project collaborators.
