As summer in London begins to gear up, the Serpentine Gallery has unveiled its new pavilion for 2015. The brightly coloured structure has been designed by Spanish architects SelgasCano, in a commemorative design that marks the 15th year of the innovative annual pavilion project. 

Made entirely from synthetic materials, the tunnel like design features four separate entrances, and none can go wrong as all of them lead to the central cafe, presented by Fortnum & Mason.

"We are proud to work with SelgasCano in this, the 15th year of a commission unique in the western world, that continues to showcase some of the boldest and innovative designs in contemporary architecture internationally," said co-directors of the Serpentine gallery Hans Ulrich Obrist and Julia Peyton-Jones.

"We sought a way to allow the public to experience architecture through simple elements: structure, light, transparency, shadows, lightness, form, sensitivity, change, surprise, colour, and materials," added Madrid-based practice SelgasCano.

The new pavilion will be open from June 25 – October 18
