The Grand Union Plastic Factory responds to the environmental neglect faced as a result of the Covid-19 pandemic. The project sees a post-pandemic future, in which advice of wearing masks is sustained by the government, seeing an increase of PPE waste all over the city that infiltrates London’s waterways. With plastic binding together with rock as a result of pollutants in water, Travis Perkins along the Grand Union Canal sees a rebranding, promoting plastic building products to reduce canal and water pollution. The site was the heart of industry within 19th century Paddington, and the project serves as an industrial renaissance of the area. Plastic and PPE waste is donated to the Institute where it is then analysed, monitored, logged and repurposed to form bricks, tiles and shingles, to then be transported to other sites along the canal. The building acts as a testbed for the products made in house while forming a dialogue with the existing sheds. Plastic stairs, balustrades and tiles coexist with the steel framework, and reuses the machinery on site for a new age of building merchants.
