S27·E5 DIY SOS at Great Ormond Street Hospital

Nick Knowles and the team join forces with two world-famous British institutions, Great Ormond Street Hospital for Children and the Royal Horticultural Society's Chelsea Flower Show, to transport Chris Beardshaw's gold medal-winning garden across London, crane it over buildings and rebuild it on the hospital's roof.

For hundreds of families, Great Ormond Street Hospital has become a second home. For parents that means being by their child's bedside around the clock, and for children, it results in a constant treadmill of appointments and treatments.

Despite the brilliant world-class care, there is nowhere private outside for the families to escape from the constant noise, bustle and bright lights of this huge hospital. The DIY SOS team and Chris Beardshaw have taken on this hugely ambitious build, with tricky logistics and emotional volunteers, in order to offer the many brave families a bespoke and lush calming rooftop garden as a space of welcome respite.
