It’s like Nordic empiricism never went out of fashion. Oslo architect Space Group designed this retro-chic, triangular faceted atrium roof for the new Clarion Hotel in Trondheim to maximise views and pull light into the centre of the building. Conceived as a ‘shattering star’, the form is apparently best appreciated from either within the complex below or from the air – it’s conveniently sited below the final approach path of the local airport. The roof is clad inside and out in manufacturer Aurubis Architectural’s ‘Nordic Royal’ golden copper aluminium alloy. Project architect Jens Niehues said: ‘The material had to meet the technical challenges of the demanding climate of the west coast of Norway... reflecting the function of the star, and giving it a rich golden colour.’
