Norwegian practices Haptic Architects and Nordic – Office of Architecture have unveiled a competition-winning proposal for a sustainable smart city on a site adjacent to Oslo airport. The 4 million sq. metre Oslo Airport City (OAC) project is set to be powered solely by renewable energy and will be served by electric vehicles, providing a blueprint for future sustainable urban developments. Embracing the exciting opportunity to design an entire city from scratch, the architects focused on implementing progressive urban-planning strategies such as walkability, appropriate density and a car-free city centre. OAC will provide housing and generous green spaces for the airport’s growing workforce, and will be a test bed for technologies including driverless electric cars and intelligent street lighting. Outline planning consent has been granted and construction of the initial phase is set to begin in 2019/20.
