A weathering-steel pavilion featuring fluid curves inspired by the movement of water formed the centrepiece of this garden presented by Studio Weave and landscape designer Tom Massey at the Chelsea Flower Show.

The garden was created by Massey and Studio Weave founder Je Ahn for international not-for-profit WaterAid, which works to provide clean water to communities around the world.

The sculptural pavilion was designed for WaterAid

With a focus on sustainable water management, the WaterAid garden featured colourful planting arranged around the sculptural pavilion, which collected rainwater and funnelled it into a collection tank to be used during dry periods.

"We wanted to demonstrate water-related design features such as rainwater harvesters, swales and depressions, as well as the planting," Je Ahn told Dezeen.

Its funnelled design channels rainwater

"The plants are ordered, from drought-tolerant arid species on the upper levels through to water-loving aquatic plants further down," Ahn added. "Part of the aim is to demonstrate a diversity of design ideas to the public."

Ahn and Massey wanted to raise awareness of the impacts of climate change, including droughts and flooding caused by heavy rain, which are particularly keenly felt by gardeners.

The pavilion at the centre of the garden was designed to harvest rainfall so it could be used later for irrigating plants.
