The show was held during last year's Copenhagen Fashion Week to present Stine Goya's Whisper Loud clothing collection, and its runway has since been shortlisted in the installation design category of the 2023 Dezeen Awards.
Spacon & X had previously worked with the brand on the set design of its Autumn Winter 2022 show, for which it erected huge screens that digitally displayed different elements of nature.
For the Whisper Loud show, the studio instead wanted there to be a "physical manifestation" of the natural world – so it decided to put 20 tonnes of sand to use.
The sand was taken from a small town north of Copenhagen called Hundested, having already been used in its annual sand sculpture festival.
It was then sent to TAP1 – the venue which hosted the Stine Goya show – and compacted into wooden boxes to form large, square blocks.
These blocks of sand were stacked into tall towers, with each block separated by a small layer of cornstarch dyed shocking pink with biodegradable food colouring.
A total of six towers were made and placed atop heaps of sand in the middle of the runway.
The piles of loose sand concealed wooden platforms that could be set to vibrate via remote controls backstage.
These were activated as the models began walking, breaking down the towers and revealing their bright-pink interior to the crowd.
"The audience did not know it was about to happen, so it was set to inspire a reaction and a conversation," explained the studio.
After the show, the sand was re-donated to TAP1, where it will be used for outdoor landscaping.
Spacon & X's set for Stine Goya's Whisper Loud show will compete against four other installations at this year's Dezeen Awards.
