Royal Neighbour

Masterplan for an industrial harbour front

Kolkajen (The coal quay) is located in Stockholm’s Royal Seaport, one of Europe’s largest development areas. Situated on the site of an obsolete gasworks and steps away from one of Stockholm’s Metro lines, the old industrial harbour offers a unique opportunity to redefine Stockholm’s relationship with its waterfront.


The masterplan is structured around its central public space - the water arena - which extends out from the existing coastline and frames a section of the Lilla Värtan waterway. Strategically placed platforms connect to the quay edge forming sun soaked public balconies that grow out of the urban structure.


The three distinct areas of the plan - Kolkajen’s Balcony, Tjärkajen’s Terraces and the Ropsten Plateau - are tied together with an eclectic mix of spaces that include a canal, linear park, waterfront square, urban boulevard and pier.

Built diversity

Typologies range from 3 storey canal apartments to an 18 storey waterfront high-rise

Waterfront Living

The urban structure embraces and maximises its waterfront location


The row house lined linear park provides an intimate and inviting play space for residents
