Large-scale transformation and adaptive reuse in central Oslo
Images of the new proposal for Oslo Horisont - KLP’s high-rise hub – have been submitted to PBE / Oslo planning authority. The scheme seeks to transform a former post office terminal into a new gateway to Oslo Central Station rail platforms, and to create a commercial multi-tenant office hub with 3500 workspaces, a hotel/ conference centre, foodcourt, cafe and bicycle parking.
Today, the post office terminal has few visitors, occupies a large area and is perceived as a massive, inward-looking building volume. The post office terminal will be converted into a multifunctional building with a range of different purposes. The existing concrete structure will serve as a base for the high-rise buildings and ensure that a part of Oslo's history is preserved. The reuse strategy retains 30,000 m² of concrete, making Oslo Horisont one of Norway's largest transformation projects.
“We are delighted and honoured to contribute to one of Norway's largest and most ambitious transformation projects together with Kristin Jarmund Arkitekter AS and Rodeo Architects. As the project takes shape, we look forward to further developing key themes such as public access to spaces high above ground level and giving identity to what will become one of Oslo's central landmarks”, says Mads Mandrup Hansen, Partner and Architect at C.F. Møller Architects.
International role model in circularity
The old post office terminal will be an airy, transparent base that will ensure that the urban pulse and movement of the city is invited in and made visible. Centrally located in the middle of the transparent base, a direct connection to escalators and lifts will be established, leading the area and the building's commuters to the platforms at Oslo Central Station. A new city floor is created with entrances and connections that will also link the building to Akerselva, Nylandsbrua and Schweigaards Gate. The urban floor will activate and connect the surrounding environment by incorporating outdoor spaces where there is human activity. The building will include functions such as office workspaces, meeting rooms, a sales hall and cafés.
Bicycle parking is integrated and a central part of the concept with its own driveway and parking basement with over 3,000 bicycle parking spaces. This comes together around a central atrium located between the two high-rise buildings. A green public landscape will be established on the roof of the old post office terminal, which will give the site back to the densely populated urban area- a green lung where human life has room to develop. All this is possible even if 70% of the existing structure is recycled and reused in the new project, which will make Oslo Horisont an international role model in circularity.
Green rooftop landscapes with a focus on recreation and life
The tallest building is 135 metres high and will accommodate flexible office space for future tenants with up to 3,500 new workplaces. The lower building is designed for hotel operations. Everyone will have access to terraces with planting, which visually appear as hanging gardens at the full height of the high-rise buildings, right down to the Akerselva. The transformation will provide space for recreation and life in and between the buildings. Right in the heart of Oslo, between the tree branches on the roofscape, visitors can experience panoramic views of the city, the countryside and the Oslo Fjord.
