The 8th of the “SPACE International Conference 2025 on Sustainable Architecture, Planning and Urban Design” will be held in London on 5-6 June 2025, online and onsite (hybridly). The Conference will explore the transformative potential of circular urbanism in building sustainable and resilient cities under the theme “Circular Urbanism: Pathways to Sustainable Development“. As urban areas face increasing challenges from climate change, resource scarcity, and population growth, the need for innovative and adaptable urban models becomes paramount. Circular urbanism integrates circular economy principles into the design and management of urban environments, focusing on reducing waste, enhancing resource efficiency, and promoting regeneration.
