“Architects HWKN have won this year’s MoMA/P.S.1 Young Architects Program competition and will install a giant spiky structure that cleans the air in the courtyard of the P.S.1 Contemporary Art Centre in New York. Nylon fabric will be stretched across a grid of scaffolding to create the pointy arms of the installation, which is to be named Wendy. This fabric will be treated with a spray that can neutralize pollutants in the air, such as car exhaust fumes. Visitors will be able to climb up inside the huge structure, while those outside run the risk of being squirted by a water cannon hidden inside one of its arms. Wendy is due to open at the end of June. Last year a twisted rope canopy occupied the courtyard for the summer, while the year before visitors could take part in circus-style acrobatics.”
