The argument that cities are not safe for children is a common reason why people move to the suburbs. This has led to unencumbered urban sprawl in Perth, with children growing up with a suburban mindset, leaving the city without custodians. To break this cycle, a design proposal has been created to bring the elements of a suburban neighborhood into the city, combining space, privacy, nature, views, local amenities, and child-friendly intergenerational living while retaining the city’s cultural richness. The proposal aims to create a sense of community, allowing the inhabitants to become custodians of their environment and pass the legacy of urban living to their children. The design is based on the 20-minute or 15-minute city concept, ensuring amenities are within a 10-minute walking radius, making walking a priority and blurring the lines between indoor and outdoor spaces. The key to creating a successful soft city is a choice of enclosed spaces designated as public, shared, semi-shared, and private, with the shared and semi-shared spaces allowing for the most meaningful chance encounters.
