"For me the garden is a treasure box of memories of different places and people and that sort of thing.
"It's a little bit nostalgic but is also contemporary in the way that it's made - there's an outdoor room which is all corten steel which is metaphorically a cave - you got into the space and because it's triangular it draws you in and down onto the ground.
"It has a lovely little fireplace at the end of it, there's suspended plants hanging from the ceiling, and there's a water sculpture which is probably the most eye-catching part, which soars 6m into the air has coloured shards of acrylic suspended on wires, so it looks like it's floating in space."
The garden took over two weeks to build onsite though a lot was done beforehand including prefabricated steel work in Steeline Industries, Otaki, and the plants were grown by Ben at home as well as Gus Evans Nurseries, Waikanae.
"We had a great time building it although the weather was challenging.
"The second day we were hit with hailstorms and then there was wind trying to tear down the trees."
Ben, who has won number of awards in the show over the years, said entering the show was more about a creative outlet as well as supporting Kate Hillier, the show's director, who asked him to create an anchor garden for the show.
"The biggest buzz for me is about the idea of coming up with something thought provoking and adventurous concepts that really push me in terms of creativity as well as the physical attributes of making it work.
"There is a real thrill is watching an idea come off the page and into three dimensions, and also the thrill it gives other fellow gardening people seeing it."
