Billed as the first garden design show to use 3D printing, alongside traditional modelling, the format allowed designers to allow their ideas to blossom without the restrictions of budgets, planting seasons or a focus on awards.
Some of the designs were unrealised projects, such as that by Jo Thompson, whose design had been meant for RHS Chelsea Flower Show in 2011 but the charity sponsor could not raise the funds.
She said: "It’s weird because it’s a garden you’ve created but not created. The last time I saw it was in the CAD designs. I was a bit more nervous doing this than a real garden because I was letting somebody else take control."
She added: "It’s putting garden design on a different level really. These are not gardens they are models in an artistic environment. It’s very different."
Other designs were created especially for the show, as in Jamie Dunstan’s miniature garden.
"It was very scary to turn up today for the first time and see it, I’m used to building gardens and you’re seeing it come together, but I’m absolutely overjoyed with how it all looks," he said.
"This design was purely for here, in real life the budget would be enormous – when I build Chelsea gardens there’s always that issue but here you just crack on with it."
Show co-creator Andrew Fisher Tomlin, who worked alongside Tom Harfleet and landscape designer Kajsa Björne on the project, said: "We have had amazing support especially our sponsors who are all very active in the industry and with free entry we are confident that it will be very busy."
Other designers taking part are Myles Baldwin (Australia), John Brookes (UK), Sarah Eberle (UK), Jim Fogarty (Australia), Adam Frost (UK) Jihae Hwang (South Korea), Andy Sturgeon (UK), Jo Thompson (UK) and Wilson McWilliam Studio (UK)
