Madrid-based architecture practice, SelgasCano Studio, has been chosen to design the 15th Serpentine Pavilion in London’s Kensington Gardens.

Announced on 4 December, the spanish practice's appointment follows on from last year's Pavilion designed by Smiljan Radic.

As a much-anticipated landmark in London over the summer months, the Pavilion is one of the top ten most visited architectural and design exhibitions in the world, according to the Serpentine Gallery.

Although well-known practices have designed the Serpentine Pavilion in the past, such as Rem Koolhaas in 2006 and Zaha Hadid in 2000, this is the third year in a row that the Gallery directors have chosen a lesser-known firm.

Director Julia Peyton-Jones and co-director Hans Ulrich Obrist said they had chosen SelgasCano Studio because of "Their innovative use of materials, bold application of colour, informed by playfulness and a passion for nature ensures that next summer’s pavilion will be very exciting."

SelgasCano Studio will be working in conjunction with AECOM and David Glover for the engineering and construction, while Goldman Sachs is the headline sponsor. Although no specific timescale has been set for the 2015 Pavilion, designs are expected to be released in February of next year.
