Chinese internet company, Tencent, who own Chinese messaging service WeChat, has unveiled the concept for a 22-million-square-foot car-free district in Shenzhen. Urban development will prioritise pedestrians and green spaces. Designed by NBBJ – an architecture firm with work with Google, Samsung, and Amazon under its belt – Net City will be roughly the size and shape of Midtown Manhattan and powered by solar panels. The project will be completed in three phases over the next seven years. The development will include offices, homes, parks and entertainment venues. Terraced buildings between one to 30 stories will overlook the coast. Once complete, the area should be able to accommodate up to 80,000 residents and workers. There will be no roads for cars; instead, residents, commuters and visitors will connect to Shenzhen via subway and travel through Net City on foot or by bicycle. Ferries will provide public transport along the waterways.
