In DTU’s multifunctional building “The Biosphere,” designed by Christensen & Co and Rørbæk & Møller Architects, warm natural materials are used to create a robust and cohesive learning environment. The atrium is 13 m high, featuring oak surfaces and Offerdal quartzite on floors and stairs.
Indoors, antique brushed Offerdal quartzite tiles and steps have been selected for their durability, slip resistance, and low maintenance needs. Outdoors, flagstones with a natural surface are laid directly in loose bedding, without adhesive or joints. All outdoor slate is installed for easy dismantling and reuse.
The material was transported from quarry to site over a total distance of 1090 km. The building is open for visits.
“We use slate both for its architectural qualities, which contribute to a distinctive ‘DTU feeling,’ and because it is a material that works very well for reuse. When we make changes – for example at retaining walls – we dismantle the slate and reuse it in new structures. That is exactly why we have used large quantities of slate at DTU, and why we will continue to do so in the years to come.”
