Barcelona Superblocks is an urban design principle that prioritises people over cars, improving the public realm of neighbourhoods, reducing reliance on vehicles and promoting alternative modes of transport. Subsequently this reduces pollution and CO2 emissions in the city of Barcelona while allowing for an increase in the levels of green space available for residents. The principle takes 9 city blocks and combines them into one Superblock bounded by major road networks. Within the Superblock people are given priority – two lane roads are reduced to one with the former car lane transformed into new green urban spaces.

Nordhavn is a multi-phase urban transformation project in Copenhagen, Denmark. The redevelopment of this smart city neighbourhood began in the early 2000s and is an ongoing process that has aimed to create a sustainable and integrated urban environment. Historically, it was originally an industrial harbour area, serving as a hub for shipping and trade. But as activities shifted, there was an opportunity to redevelop the area for a more modern and sustainable purpose. The redevelopment has been divided into several phases, each focusing on different aspects of the neighbourhood, including residential, commercial, transportation, and public spaces. These phases have been implemented over time to ensure that the development aligns with sustainability goals, community needs, and changing urban planning standards.
