play pavilion with LEGO bricks designed by sir peter cook

Serpentine and the LEGO Group unveil the Play Pavilion designed by Sir Peter Cook in London’s Kensington Gardens. The public art project coincides with World Play Day on June 11th, 2025, and rightfully so with the playful and vibrant flair of the pavilion. It is on view from June 11th to August 10th, 2025. The only orange on the horizon, the Play Pavilion by Sir Peter Cook partially comes to life with the use of LEGO bricks. Outside, these colorful blocks create protruding, tactile installations resembling topography. A kaleidoscopic roof shaped like a small bowl cocoons the architecture, colored in orange to match the similar shade of the base. Around the pavilion, the walls have slopes and peaks, mimicking the waves crashing onto the shore while creating different openings and exits.

Anyone can run their hands along them and feel the LEGO-brick installations on the walls before they step inside the Play Pavilion. Here, sunlight passes through the openings because Sir Peter Cook didn’t join the roofing to the base. Air and light, then, flow in and out, and people can see the outside from inside. The use of LEGO bricks continues inside. The central pillar is reminiscent of a towering robot, a quiet sentry that surveys the space to check if everyone’s enjoying their time. To exit the structure, visitors can either walk towards one of the openings or use the yellow slide on the other side. On one of the walls, there’s a brick-built board and a treasure of LEGO blocks just below it, so visitors can pick up pieces, pin them onto the interactive structure, and shape them into how they want them to be. It’s the essence of the LEGO-built Play Pavilion, an intentional design by Sir Peter Cook.

Sir Peter Cook describes the Play Pavilion with LEGO brick designs as a piece of theater, but the structure can recall the form of an observatory, too. From afar, the geometric roof already announces the presence of the orange playground. As visitors walk up closer to it, they then see the partly obscured body that completes it. In a location full of greenery, the Play Pavilion breathes in a refreshed life, luring in the visitors to come closer and find out more within. In the words of the architect, ‘a child might pop out on a slide, another may crawl through a hole on the ground, mystifying conventional entrance routes. Another mouth-shaped opening reveals an orator, performer, or singer entertaining eavesdroppers beyond.’

The LEGO-built Play Pavilion by Sir Peter Cook continues the series of programs presented by Serpentine. In 2022, Serpentine, the London Lions Basketball Club, and artist Alvaro Barrington partnered with CONSUL, Tower Hamlets Council, and Weavers Adventure Playground in Bethnal Green to create a basketball court. Today, it’s an orange pavilion that doubles as public art, with walls that present a series of tactile installations. For the gallery, these new initiatives bring together artists, designers, architects, and creatives to champion the spirit of play and community. The LEGO-built Play Pavilion by Sir Peter Cook is a platform for live activations throughout the summer of 2025.
