‘At this stage he did portals, and I thought they were fantastic,’ Ulrike recalls. ‘A portal is a transition, they have so much meaning.’ She was so drawn to his work that, although he lives and works on the Gold Coast, she approached him about a commission for the UKARIA garden. He enthusiastically agreed. ‘At that point we didn’t even have a garden – we had only just started the building, and only the foundations were there,’ she says. ‘But he knew the space, and had a sense of the environment. It’s all so connected.'

A gift to UKARIA from Jurlique to mark its thirtieth anniversary in August 2015, Sound and Space is constructed of Kimberley Pearl Granite from Western Australia. ‘The two halves, split and cracked from the one block of granite, curving inward, draw the viewer into the work,’ Luke writes. ‘A portal where the physical body cannot enter, only light, mind and soul may pass through. This journey and transformation happens also when listening to sound, music and meditation.’
