Today, the long-awaited summer pavilion of the London Serpentine Gallery by the trio of South African architects Counterspace opens to the public. Unlike in 2004, when the Dutch studio MVRDV was unable to realize the bold project of an artificial mountain within the given timeframe and with limited resources, this time the construction of a temporary structure in Kensington Gardens was hindered by a global pandemic. Sumayya Vally, Sarah de Villiers, and Amina Kaskar from the Counterspace studio (*2015 Johannesburg, RSA) thus received an additional year to improve their original design, which is the most environmentally friendly in the twenty-year history of the Serpentine summer pavilions, as it uses K-Briq bricks made of 90% recycled construction debris. These blocks do not need to be fired, consuming only one-tenth of the energy required compared to traditional bricks. The second sustainable material in the construction will be cork cladding from Portugal. The bark from the cork oak can be harvested every 8-12 years without the tree needing to be felled. This year, the American magazine Time included Sumayya Vally (*1991 Pretoria, RSA) in its list of one hundred people who will shape history (2021 TIME100 Next). In a relatively short time, Counterspace has developed its own language that celebrates the African continent and its diverse textures and cultures. They strive for their designs to have a significant social impact. This groundbreaking London commission brings Counterspace to the international stage, offering a change for future generations. While previous pavilions reflected the personality of the creator, this year's authors pose urgent questions hidden deep behind the form. They are interested in the sources of the materials used and are also planning a discussion program focused on sharing experiences of migrant communities living in London. The temporary structure will be accessible in Kensington Gardens until October 17, 2021.
