This week, Dezeen spoke to Björk in an exclusive interview, and reported on the fire that devastated Charles Rennie Mackintosh's Glasgow School of Art.

Icelandic musician Björk described the process of designing the costumes and sets for her Uptopia tour, with her inspiration coming from classic Icelandic paintings and summer nights.

"It needed to look fertile and potent, that there is a erotic energy there, a potential for multiplying but also a little scary, a little fucked up, a comedy element to it too," Björk told Dezeen.

The Glasgow School of Art, the seminal building by Scottish architect Charles Rennie Mackintosh, was ravaged by a fire for the second time in four years.

There were differing views on what should be done following the fire, with Mark Cousins, an architecture fellow at the University of Edinburgh, arguing that it must be rebuilt, while Alan Dunlop stated that to honour Mackintosh's legacy, we should come up with new ideas for its replacement.

In a technological first, Dutch bike company VanMoof launched a high-security electric bicycle that claims to be impossible to steal.

Also designer Benjamin Hubert created an innovative wearable device that lets aspiring football players and athletes improve their performance.

In British architecture news, a home in an old gin distillery and a house that cost only £100,000 made the longlist for the RIBA's House of the Year 2018.

RIBA also revealed its National Awards, which recognise the best British architecture of the year. Award winners included the Tate St Ives, Bloomberg's Foster + Partners-designed London HQ, and a housing development in old gasholders. 

In London this week, Christo unveiled a giant 20-metre-high installation on London's Serpentine Lake made of 7,506 floating plastic barrels.

To mark the occasion we reflected on the most arresting temporary art interventions from the past 50 years that Christo and the late Jeanne-Claude have created.

Popular projects on Dezeen this week included Instagram's new Manhattan offices designed by Gehry Partners and David Chipperfield Architects' offices for Korean beauty giant Amorepacific in Seoul.
