A sandbox project, exploring the notion that a large swale in the Broadway in Winchester would provide valuable environmental and social benefits. A nod to the historic presence of open rivers in the area, sustainably resolving local drainage problems and freeing a potentially valuable civic resource from its fate as a barren, car dominated space into a ecologically rich setting for the Guildhall and Abbey Gardens.Once you get above the roofline of Winchester you realise how barren and underused the rooftops are. What if all suitable roofs were green and used for recreation and relaxation? Another suitable question for a sandbox test exercise. Green roofs bring many benefits, including biodiversity enhancements and habitat creation for birds, insects, and pollinators. They enhance the connectivity and diversity of urban green spaces and the ecological value and resilience of the city. Panoramic views of the cityscape and sky offer a unique and memorable experience in attractive and accessible spaces for people to enjoy nature, socialize, dine, and unwind. A string of roof top gardens would increase the economic and social value of the city centre area and foster social cohesion and inclusion in spaces for cultural and community events.
