In 2013-2014 Stockholm County Council arranged a parallel competition to develop Norra Hagastaden, a sub-area of Hagastaden. The proposal from Rundquist architects in collaboration with Nivå landskapsarkitektur and Ramboll was selected for further work with a planning program.

The project is located on the border between Stockholm and Solna and includes the current Karolinska Hospital area whose activities to the most part will move out to the southwest part of the neighborhood. The ambition is to develop the former hospital area to a district where housing, education, research, health, culture and entrepreneurship are united in a structure that create meetings and city life
