As one of three architectural firms in parallel assignments in 2014, FOJAB produced an urban development proposal for Kolkajen - Hjorthagen's waterfront in Stockholm Royal Seaport. The procurement also included a framework agreement for the design of public environments in Stockholm Royal Seaport and work on formal detailed plans.

Norra Djurgårdsstaden is one of the largest urban development areas in Stockholm and northern Europe. The area will, in a sustainable and resource-efficient way, accommodate about 35,000 workplaces and about 12,000 new homes with associated services and infrastructure. The current phase, Kolkajen - Ropsten, is located between Hjorthagsberget and Lilla Värtan, next to the bridge to Lidingö. To the southwest is the Ropsten metro station.

The area is currently industrial land. The area contains the culturally and historically valuable Vattengasverket and a heat pump plant for energy production that will be preserved.

The parallel assignments investigated how Hjorthagen's future entrance and waterfront can be designed with a focus on public urban spaces and parks. The starting point was both overall objectives regarding transport, energy, cycles, buildings, greenery, lifestyles and activities, as well as the specific character and conditions of the site. The goal is a dense and mixed neighborhood with a strong identity and high urban design qualities. Not everyone will be able to afford to live here, but everyone will be able to spend time here and enjoy the social life and proximity to the water.

The work began with the parallel assignment and FOJAB was also awarded a framework agreement with the Development Office of the City of Stockholm for the work on Norra Djurgårdstaden. The work included producing a detailed plan, design program, and program and system documentation for street and play environments in the area. The street spaces are important links in the new district and will be designed with a focus on stormwater, greenery and quality of life. On the waterfront, we design a large playground with a natural character where lush trees and undulating wooden structures create a stimulating play environment.
