An iridescent art installation is set to appear at the foot of a London skyscraper featuring bubbles enveloped by 20-foot high rainbows.

Elysian Arcs created by design studio Atelier Sisu will pop up at The Leadenhall Building - affectionately known as the cheese grater - on Monday February 26.

Their creators hope the free light and sound installation will bring joy and colour to City workers in the darker months of the year.

The free installation has been commissioned by the Eastern City Business Improvement District to help support the mental, physical and environmental wellbeing of workers in the City and across London.Ham & High: CGI image of what the artworks at The Leadenhall Building will look likeCGI image of what the artworks at The Leadenhall Building will look like (Image: Atelier Sisu)

It will be open for all from 10am-8pm daily until March 15 and is led by award-winning artists Renzo B. Larriviere and Zara Pasfield who work at the intersection of art and architecture on large-scale site-specific works.

The arcs are made from a colour reflecting dichroic film that reacts to changes in light causing a rainbow of reflections. They are enveloping clusters of evanescent bubbles and it's hoped the artwork will become impressive at dusk with internal lights bringing it to life.

An ambient soundtrack will invite people to move around and underneath the structures, to reflect and recharge.

Kate Hart, CEO of the EC BID, said: “Supporting the mental, physical and environmental wellbeing of workers and young people within our Eastern district is a huge priority for us.

"We as a BID recognise the importance of culture within the City and we will shed some light, quite literally, on the amazing spaces and people within it. Elysian Arcs is a beautiful immersive experience for all ages to enjoy whether you are a visitor or a worker wanting some time out from a busy day."

Renzo B. Larriviere and Zara Pasfield of Atelier Sisu, said: “We are incredibly pleased that this piece of art can go some way in improving people’s mental, physical and environmental wellbeing in the darker months of the year.

"Elysian is our visualisation of joy. The very word Elysian relates to the characteristics of heaven or paradise, something we hope people will feel from the installation itself."
