The Visaginas pedestrian avenue reconstruction project aimed to preserve the city’s original spatial structure while introducing modern, eco-friendly solutions. Built in 1975 for nuclear plant workers, Visaginas thrived until the plant’s closure in 2009, which impacted its growth. The renovation retained the avenue’s historic proportions while enhancing sustainability through 1,000 sq. m of rain beds with perennial plants, which collect 90% of rainwater and increase greenery by 30%. These improvements have revitalised the area, fostering social interaction and transforming it into a beloved gathering spot for the community, ensuring a balance between historical preservation and contemporary urban needs.
