Located in Oslo, Sannergata 2 stands as a strong example of how Norwegian natural materials can be used in modern urban architecture. The entire façade is clad in Norwegian natural stone – with Lundhs Grey™, larvikite supplied by Lundhs and Ice Green granite. The result is a cohesive and durable façade solution where quality, craftsmanship, and sustainability are paramount.
Throughout the project, Naturstein Montering has been a key partner, responsible for installing the façade in Lundhs Grey™. The work included custom-designed anchoring and suspension systems, including bespoke solutions for the columns along the south façade.
– “Naturstein Montering has delivered and installed a beautiful natural stone façade at Sannergata 2, executed entirely in Norwegian natural stone. They were among the first subcontractors contracted for the project and contributed closely to the design of the anchoring solutions and the coordination with other contractors involved in the façade delivery. We appreciate the excellent collaboration,” says Knut Reidulff at Vedal.
A comprehensive transformation
The project, developed in collaboration between Vedal, Ragde Eiendom, Kristin Jarmund Arkitekter, Nordic Office of Architecture, and Krohnark, includes the rehabilitation of 20,000 m² of existing building mass and the addition of 4,000 m² of new construction. The building now houses office, retail, and hospitality spaces – with Ragde Eiendom’s new headquarters located on the top floor.
The transformation has given the building a completely new identity – from an anonymous office block to a modern architectural landmark. With its stone façades, large floor-to-ceiling windows, and clear architectural gestures, the project showcases how existing buildings can be upgraded using long-lasting and sustainable materials.
Sustainability and certification
Environmental considerations have been central throughout the project, and the ambition of achieving BREEAM Excellent has been realized. A 730 m² solar panel installation on the roof is expected to produce approximately 113,000 kWh of renewable energy annually – equivalent to a reduction of around 53 tonnes of CO₂ per year.
