Each year the Serpentine Gallery in London’s Hyde Park builds a new Summer pavilion, each designed by a famous international Architect. This week we visited the latest, designed by Architect Peter Zumthor. Many previous pavilions have focused on daring shapes, but in contrast this year’s design is a more thoughtful example of how simplicity can be powerful, through careful handling of light, shade, space, materials and colour. Zumthor has created a contemplative retreat space, centred on a wildflower garden. The complexity and drama of nature is cleverly offset against the stark rectangular form of the surrounding architecture. The dark perimeter corridor creates a sense of entrance and anticipation, before the bright colours of the central atrium are revealed.
