Can Kalejdohill become a positive force for action in society?

Kalejdohill is a two year research and communcation initiative on urban planning and social research, directly linked to the area Kvarnbacken in central Jakobsberg, Järfälla Municipality. 

The object is to investigate and generate ideas on architecture, design and social sustainabilty. The project is thus based on communication with residents and visitors as well as inspired by national and international experts from the fields listed above.

The project was initiated by Håkan Berg, CEO at HSB Norra Storstockholm, and is managed in cooperation with Veidekke Bostad and Einar Mattsson. The objective is clear: to develop the area in dialogue with its inhabitants, while at the same time helping to develop Järfälla as a destination during the present sharp expansion and extension of Järfälla municipality.

The starting signal for the Kalejdohill project came about when Järfälla municipality and HSB Norra Storstockholm signed an agreement on 600 - 800 new dwellings around Kvarnbacken in the centre of Jakobsberg. Together, the municipality and HSB wanted to create a multi-functional destination and an attractive meeting place – built around architecture, design and art.

Over a period of two years, Kalejdohill will help develop Järfälla as a locality, focusing on central Jakobsberg and Kvarnbacken in particular. Kalejdohill is the project that will turn Järfälla and Jakobsberg into a locality for social progress, architecture and design. A locality that many people would like to visit, invest in, take an active part in and make their home. 

The work is based on a few guiding premises or principles, and our vision is to create the opportunity to establish a new design and architecture centre, adapted to today’s need for meeting places, housing, communication and lifestyles. 

  • Kalejdohill makes a start at Kvarnbacken locality and examines and communicates new locality and destination development forms.
  • Kalejdohill’s cornerstone is commitment today for social sustainability in the future.
  • Kalejdohill employs architecture, design, art and communication to fill Kvarnbacken with content and life – long before the houses are built.

Kalejdohill builds on the engagement and ideas from many individuals. This is how we initiate and manage projects and fill Kvarnbacken with exciting content. 

Basically, destinations and cities are built on two components: their place on the map and their network. For Kalejdohill, the network has been a cornerstone. HSB Norra Storstockholm launched the initiative, and soon brought with them Veidekke Bostad and Einar Mattsson. Järfälla municipality has been part of the project from the very start. We are always open to interesting collaborations. Most importantly, in addition to the investors and strategic partners listed below, we continue to work together with the inhabitants of Järfälla. We organise workshops, offer young people summer jobs at Kvarnbacken and much more. Keep an eye on our news page for more information on what’s going on.

Where is Kalejdohill?


Kalejdohill will use Kvarnbacken, in the centre of Jakobsberg, as the scene of action. Kvarnbacken is a green, beautiful, central and historical locality in Järfälla – one of the fastest growing municipalities in the region, and indeed all of Sweden.

The population is expected to grow from today’s 70 000 to nearly 100 000 in 2030. And the urbanized area is dense. Therefore, around 600 - 800 new dwellings will be built around Kvarnbacken.

The agreement to put one or several spades in the ground and start construction was reached in connection with a land notification agreement between Järfälla municipality and HSB Norra Storstockholm on 14 December, 2015. The land notification also marked the start of the Kalejdohill project. Or conversely, the Kalejdohill project, then known under the working name “The Mill”, was the starting point and a precondition for the housing development around Kvarnbacken.



Kvarnbacken is a green and beautiful place with an interesting history, covering approximately 7 acres in central Jakobsberg. Originally, Kvarnbacken was a grave field from the early Iron Age. Overall, the area contains some 100 graves from the Viking era, visible as small hills or mounds.

On the top of Kvarnbacken, the remains of the burnt down mill can be found. The first mill on Kvarnbacken was erected in the 1780s. The mill employed 26 millers until 1926, when operations ceased. After that, the mill changed owners several times before Järfälla municipality purchased the property in 1957. The mill was ravaged by fires in 1980, 1997 and finally in 2005, after which the mill was not rebuilt. Today, all that remains of the old mill is the concrete foundation.

From the top of Kvarnbacken, Jakobsberg's Gård can be seen to the north, accentuating the historical connection between the manor house and the mill. Jakobsberg's Gård and Kvarnbacken are important for understanding the emergence and historical context of Jakobsberg. Today, only 500 metres separate the north-eastern part of the area from Jakobsberg centre and the commuter rail station. In the future, the Stockholm metro system may be extended all the way to central Järfälla and Kvarnbacken. 


Järfälla, northwest of Stockholm, traces its history to the Stone Age, with the name having existed for at least 700 years. The area was Christianised in the 11th century, and a first church was built around the year 1200 – and it still stands today. Järfälla continued to be of some importance in the Middle Ages as several important thoroughfares passed through it. The main population expansion came in the 1930s and 1940s, when middle-class families moved away from Stockholm.

Today, Järfälla is one of the fastest growing municipalities in the country, just as it was in the 1960s. In the early 1990s, IKEA opened a store in Barkaby, paving the way for a new extensive commercial area, and later, a significant residential expansion in Barkarbystaden. The name Järfälla means “wedge-shaped meadow”.

Jakobsberg is the commercial and administrative centre of the municipality. Jakobsberg Centre includes shops, offices, car parks and apartments, as well as a library, an art gallery, an exhibition hall and a cinema. There are a number of ancient monuments and buildings of historic interest in the area. There are around 24 000 people living in Jakobsberg, while the municipality has total population of 70 000.
