Langarth Garden Village is a planned sustainable community near Truro, Cornwall, England. Once completed, it will provide approximately 3,550 homes for 8,000 and 10,000 residents. The development aims to create a vibrant, well-connected community with a strong emphasis on sustainability and quality of life. Cornwall Council has invested £160 million into the project, with construction expected to span 20 to 25 years. The development is part of the UK government's Garden Communities programme, which supports creating sustainable and well-designed communities. The project has involved extensive community engagement, with over 200 public consultations to ensure the development meets the needs and aspirations of residents. The master plan's design principles focus on enhancing quality of life, promoting active lifestyles, and fostering a strong sense of community.
