OBOS – Stadsljus

Yellon, in collaboration with Copenhagen-based Cobe, won the parallel commission announced by OBOS and the City of Stockholm in May 2023. Our proposal for Stadsljus (formerly Gasometer 4) connects to the historical gasometers of the area while adding a unique modern character and residences beyond the ordinary. Sustainable qualities for a long time to come.

Stadsljus will enrich Norra Djurgårdsstaden and provide Stockholm a new skyline. Rising 110 meters above sea level, the building capture daylight through its angled surfaces, ensuring optimal living conditions in each apartment. In total, the project covers 36,000 square meters distributed between businesses on the ground floor and approximately 300 apartments.

The design seamlessly integrates with the area’s cultural and historical context. The location is unique with its large, round gasometers, the most famous designed by Ferdinand Boberg in the late 1890s. Inspiring our overall circular design, the existing gasometers and Stadsljus as the new generation will form a family with harmonious features.

While the circular identity was the starting point, we adapted it to today’s residential demands. By combining three cylinders, smaller volumes are created to meet high sustainability requirements for daylight, indoor climate, and energy performance. Simultaneously, an interesting tower with smaller and more vertical proportions is achieved. The frame system also allows for flexible residential planning and efficient production.

A characteristic feature of the historic gasometers is the large vertical brick columns. These are reflected in Stadsljus’s base, where the brick elements provide the ground floor with high detail and material quality. The prismatic body is inspired by the industrial language’s rational and repetitive structures. The compact form enables energy-efficiency, and the three cylinders provides generous natural light and apartments in several directions, offering beautiful views. The facade’s complex shell of balconies, both matte and glossy surfaces, contrasts with a rational construction. The crown, similar to two of the existing gasometers’, marks the location in Stockholm’s silhouette. Additionally, technical units are hidden, and the angled panels are covered with solar cells.

The landscape architecture also restores the Gasverket area to its former glory. Stadsljus is planned to be completed by 2028, with move-ins starting in 2029.
