Oslo is extending its metro to reduce pressure on the surface network and facilitate access to the city centre. The new Fornebubanen metro line will feature six stations from the centre of Oslo to Lysaker, in the Fornebu suburb, to the west of the city. Arup delivered the architectural design for the Lysaker interchange metro station, from concept to detailed tender design.

Arup’s architectural vision for Lysaker is to deliver a fully accessible station with cost-effective maintenance. Design highlights include warm colours for an instant mood lift and a single entry-exit pavilion for easier wayfinding. A green roof will handle rainwater.

The Lysaker interchange station will integrate metro, train and bus links for over 24,000 passengers daily. Arup’s design enhances the passenger experience, ensuring accessibility and providing intuitive wayfinding throughout the journey.

Enhancing the passenger experience

Passengers will enter the station through a single entry-exit pavilion lit by daylight and LEDs. They can access the mezzanine via 11 escalators and seven glass lifts to reach the under-river station and 120-metre-long platform between the tracks.

During the long winter nights, the warm colour palette of the interior design will create a welcoming ambience. We used ceramic terrazzo tiles, timber and aluminium panels, and weathering steel for the external façade. 

Made out of locally sourced timber, the external roof structure will be topped with a green roof that can harvest rainwater and prevent flooding. 

Improving the indoor environment

We designed a cladding solution that allows high-speed trains to pass through the station without stopping.

To cater for the high wind loads below ground, we designed a fireproof structure with sound-absorbing perforated aluminium panels. A light, non-combustible material will clad the tunnel ceilings and hide the smoke ventilation, making the space less noisy and windy for passengers.
