By 2030, it is inevitable that the amount of waste in our ecosystem will have drastically increased. One of the main components of this waste will be coffee. Unfinished lattes, crumpled cups and coffee grounds currently account for more than half a million tonnes of landfill waste annually in the UK. Currently, companies are looking into different ways to reduce coffee-related waste, one example being turning coffee grounds into biomass and burned as fuel, providing the inspiration for this project. The Coffee Ground, located at 35 Horn Lane, Acton, utilises waste coffee grounds as its building aggregate to create rammed earth walls. With the coffee ground as its base, the building serves as a coffee house, suitable for local residents of all ages, as well as businesses in the immediate vicinity. The building’s topmost floor serves as an event space, available to a wide audience. With the development of HS2 and Crossrail in mind, the building envisions this area of Acton as a destination point, rather than a liminal space.
