Ör Centrum - Sweden
Contact us
Once finished Ör Centrum, a new residential development not far from the centre of Stockholm, will be a vibrant, modern and ecologically sustainable district. It will be 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.
A diverse and linked residential scheme
Encompassing more than 16,000 square meters, Ör Centrum is 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 neighbourhood 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 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.
Quick and sustainable construction
Ör Centrum is a timber-led building where the three buildings are formed of cross laminated timber (CLT) with the basement and ground floor formed of concrete and steel. The timber-led approach is a fundamental principle for the client Folkhem in order to realise a highly sustainable development and also to enhance comfort and aesthetics for the residents by creating a more natural and liveable environment.
The walls and floors will be made using CLT which can be locally sourced in Sweden and brings many benefits to the scheme. The scheme will sequester 3000 tons of carbon dioxide. Local sourcing of the timber, together with a preference to source all materials from the geographically closet suppliers wherever possible, will reduce the number of deliveries to site and the associated carbon emissions. And through careful planning and preparatory work, the production time on site will be shortened by around half the time compared with traditional prefabricated concrete construction and create less disturbance to adjacent properties.
Optimised and harmonised design
Arkitema Architects designed the new block with Ramboll serving as technical consultant and providing structural engineering and M&E services. Through close collaboration we project partners, we ensured all aspects of the design were fully optimised. WSP’s fire strategy includes sprinkler systems, escape routes and surface treatment of the wooden structure, with Acouwood focussed on the acoustic performance of the building and ensuring the fire and acoustic strategy were harmonised as one.
The project is currently out for public consultation prior to receiving outline planning approval.
