Kate Middleton is set to reveal a giant wooden treehouse inspired by her Chelsea Flower Show garden.
The Duchess is due to open her Back To Nature garden at RHS Wisley in Surrey next week - with the focus of the garden being an incredible children's treehouse.
Featuring walkways, ladders, a slide and swing, the treehouse is designed to give children the room to play and explore their natural surroundings.
Kate, 37, took inspiration from her first garden at the Chelsea Flower Show - the 'Back to Nature' garden designed by Kate Middleton herself along with leading landscape architecture firm Davies and White, led by Andrée Davies and Adam White.
However, her Surrey garden at the RHS Wisley show is reportedly much more child friendly, featuring a sandpit, swings and a hut made to look like a hedgehog.
Kate, a keen gardener, advocates for spending time amongst nature - and even got George, Charlotte and Louis involved in her Chelsea Flower Show garden.
They were pictured playing amongst the foliage and near a tee-pee made from sticks.
Older siblings Prince George, five, and Princess Charlotte, four, were seen dangling their bare feet over a stream of water as the family look happy and relaxed.
Prince George gave an adorable verdict on his mum's first gardening efforts for the Chelsea show.
After his father asked him what he thought of it, a proud George awarded it a glowing score of "Twenty".
The Duchess of Cambridge also revealed her hopes it would encourage youngsters to get out and explore nature.
She told the BBC that technology-obsessed youngsters were "missing out" and added that her children were dragged to play outside come "rain or shine".
The garden features a tree house, swing seat, waterfall, rustic den and a campfire as well as tree stumps, stepping stones and a hollow log for children to play on.
It was also revealed that the Duchess was involved at every stage of the design - including the difficult gardening work.
She met youngsters in activities around the garden - such as making boats from reeds - that demonstrate some of the creative and active skills that children can learn from being in the great outdoors.
