Floating Copper Drum
An intriguing floating drum incorporating layers of perforated copper from Aurubis invigorates the central square of Trondheim, Norway, transforming into an animated light source at night.
The competition-winning scheme formed part of a larger, currently unexecuted, plan to renovate and upgrade the town square, Torvet, as a whole. Architects HUS arkitekter AS wanted to create a new, lively space focused on activity – a space bursting with people and life. The new stage is located in the southwest corner of the square in front of a shopping mall. The stage itself is multifunctional without any dedicated use and is dominated by the main attraction – the cylinder-shaped stage ‘loft’.
The cylinder consists of three layers: the inner reflective surface is polished stainless steel with a random pyramid pattern; the middle screen is Nordic Standard copper with clear lacquer to keep its natural colour over the years; finally, the outer skin is randomly hand-patinated Nordic Standard copper. The green patinated copper canopy changes its appearance in different daylighting conditions. Then, the drum transforms in the evening with light from the inner circle reflected throughout the screen. It was conceived as a living element, changing expression with the rhythm of the day.
The two copper layers are perforated for transparency in a random pattern of hexagons of varying sizes. Between the middle and inner layers there is multi-coloured LED lighting arranged in five height zones, facing inwards. And between the outer and middle layers, on top of the structure, LED wall-washers face downwards.
Along with three other Aurubis copper or copper alloy clad projects, HUS arkitekter’s Torvet Drum has been shortlisted for the 2017 European Copper in Architecture Awards: http://copperconcept.org/en/awards.
Nordic Standard ‘mill finish’ copper is produced by Aurubis, part of the world’s leading integrated copper group and largest copper recycler. The Aurubis architectural range also includes Nordic Brown pre-oxidised copper, offering lighter or darker shades of brown determined by the thickness of the oxide layer. Various Nordic Green, Nordic Blue and Nordic Turquoise factory-applied patinas have also been developed with properties and colours based on the same brochantite mineralogy found in natural patinas all over the world. Aurubis copper alloys include Nordic Brass – also available with a pre-weathered finish – Nordic Bronze and the innovative Nordic Royal, with a rich golden through-colour.
