Have you taken your photos of this year’s Serpentine Pavilion yet? I have. It’s irresistibly psychedelic, as though the sixties had come back to life in Kensington Gardens. The pavilion may look odd as you walk past it on a sunless day, but go inside when the sun’s shining and you won’t be able to resist getting out the phone and snapping away. 

The annual Serpentine Pavilion is always eagerly awaited. The Serpentine Gallery commissions a new architect each year to design and build a temporary pavilion for the summer on a space next to the gallery, a place for people to chill out and admire, somewhere to challenge architectural conventions, to excite and amaze. This is their fifteenth pavilion.

This year’s pavilion is by Spanish architects José Selgas and Lucía Cano. It’s made out of panels of multi-coloured fluorine-based polymer and looks from outside like the chrysalis of a particularly colourful caterpillar.

On the inside the sun diffuses through the translucent skin to create rich patterns of glowing colour.

Woven webbing in some parts enables you to look through the structure and creates ever-changing contrasts and new colour combinations.

The architects say their inspiration came from the ways in which people move through London, especially the many-layered, chaotic yet structured flow of the Tube.

My favourite among the pavilions remains the 2013 pavilion designed by Japanese architect Sou Fujimoto, but there’s certainly plenty of fun to be had with this year’s offering. And yes, it’s a great place for interesting selfies.

The Serpentine Pavilion is open daily from 10am to 6pm until 18th October. Entry is free, and there’s a Fortnum and Mason pop up tea shop and ice cream stall inside.
