Fredrikstad is a showcase for retrofitting, transforming a former hospital complex into a residential and commercial area, called Cicignon Park. The hospital - Østfold Hospital, located in downtown Fredrikstad, has a property portfolio of 55 000 m2 and a plot area of 35 000 m2. In December 2014, Nordic Group Development AS bought the hospital and construction of Cicignon Park was expected to commence in April 2018. The private developer’s visions for Cicignon Park are (1) high environmental profile, (2) high architectural quality, and (3) high level of satisfaction on a European scale. Significant internal and external resources have already been devoted to study the opportunities, challenges and resources needed for the realisation of these visions. The SiEUGreen project will support intensive testing of innovative Urban Agriculture-related technologies on site.
