Timeless Nordic Brass Weathered


A


new commercial building in Stockholm is defined by its carefully detailed facades of Nordic Brass


Weathered pre-oxidised copper alloy from Aurubis.


In the Nattugglan neighbourhood on the island of Södermalm,


developer


Vasakronan has replaced an inefficient and outdated office block with a new, ‘LEED Platinum’ certified modern building. The new Folkungagatan 44 project provides 22,000 m2 of space, largely for offices but also including conference spaces, plus retail outlets and a restaurant on the open, street-facing ground floor. Equator Stockholm Architects’ design for the new building reinvigorates


its pivotal location.


Its massing comprises


a five-storey block with two further storeys, each stepping back to generate ‘living roof’ gardens. The building’s strong presence in the city is defined by its almost classically structured facades of fenestration and Nordic Brass Weathered cladding with a natural colour that complements its surroundings. Carefully detailed and executed flat panels, ‘fluted’ mullions and horizontal mouldings between windows, copings and other details align clearly expressed vertical joints throughout. The


Nordic Brass Weathered alloy provides a rich, copper naturally varied brown surface with a high quality, ADF02_Aurubis_External Envelope - Cladding & Facades_HPAdv.indd 1

timeless character. The surface is created by burnishing at the Aurubis copper mill, providing straightaway the same oxidised brown surface that otherwise develops over time in the environment.


The Nordic Copper alloy cladding also adds to the building’s ‘LEED Platinum’ certified sustainability agenda. Copper architectural


Nordic products and alloys


are manufactured using 100% recycled raw- material, and copper’s ability to be recycled repeatedly – without any loss in performance – is an important sustainability benefit.
