Örban Stockholm - a sustainable residential project
Once finished Ör Centrum, not far from the centre of Stockholm, will be a vibrant, modern and above all an ecologically sustainable district: designed as one of the largest all-wood neighbourhoods, consisting of close to 4200 cubic meters of wood which will sequester approximately 3000 tons of carbon dioxide.

Spreading across more than 16,000 square meters, Ör Centrum is being designed and built as a residential structure rising to 32 meters in the sky with close to 200 residential units between the 4th and 10th floor. On the ground floors facing the streets there will be a communal area with shops and cafés. The neighborhood aims to be diverse both in ownership structure and across age groups, as some flats will be rented out and others sold. There will also be a senior citizens home.
The courtyard will link the complex together with the existing buildings and will be open to everyone in the area with an emphasis on easily crossing the block. Private gardens for the residents will be placed on the roofs in the form of roof terraces with greenhouses. Ensuring dynamic and playful expression there will be different floor heights, protruding bay windows and balconies.
The project is divided into three buildings in Cross Laminated Timber (CLT) on top of a basement and ground floor in concrete and steel. The material for the buildings has been an obvious choice with timber in focus and especially CLT which minimizes the impact on the environment and creates a livable and natural environment for the residents. Constructing with wood creates no carbon dioxide emissions, rather the wood sequesters carbon dioxide from the atmosphere.
“With wood as a building material we can shorten the construction program by up to 50% and reduce the disturbance to the adjacent properties, even through building in timber is a very quiet building form.” Folkhem, client.
Ramboll has provided structural engineering and M&E services for this design scheme under 2018. The project is currently out for public consultation prior to receiving outline planning approval.
- Zero carbon emissions:
- CLT construction time is half compared to concrete.
- CLT's density is about 25% of concrete, i.e.
- Lower transport emissions
- Lower foundation cost
- Reduced environmental impact
