The garden is sponsored by KBI (UK).
Fagg said: "I was shocked to read in the RHS report Why We All Need Greening Grey Britain that more than 7 million UK front gardens contain concrete and cars, rather than flowers and grass, and that this has been increasing considerably over the last decade.
"I've created a front garden that shows how you can have a functional, but also beautiful garden that helps wildlife. I want to inspire visitors to bring a bit more green into their front-garden space, and the ideas within my garden are all achievable, meaning anybody can do it. Many of the materials chosen are reclaimed, like the old scaffold boards for the beds, and the bricks at the entrance.
"Beneath a lush green roof canopy there's a parking space, made from firm but porous materials that soak water naturally into the ground providing a better resource for plants and reduce flooding," said Simon. "I've also chosen flowering plants like white borage which attract pollinators and the native beech hedging which is easy to manage, also attracts pollinators and provides a perfect habitat for birds to nest in.
"You don't need a bowling green style lawn in your front garden. I've used thyme in the gravel pathways and lots of clover in the lawn areas which can be walked all over, don't require fertilizer and can flourish in poor quality soil.
"I've also used a Keyhole garden, an African concept," Simon said, "which has been embraced by the West and is easy to install in your own garden, and is really effective at conserving rainwater."
Back to Back Gardens return this year. These 6 x 4 metre designs include Peter Shirley's 'Rosy Hues' which is "inspired by the thrill of transforming a pre-used or empty space into a living garden with colour and scent, the garden offers a place to escape".
'Slow and Preserve', designed by Andrew Rouse, "also aims to highlight what can be done to regenerate urban areas that have been left ignored or unused".
Lindsay Haycock found inspiration from her own front garden and demonstrates the unfilled potential of the space around us with 'Bring Me Sunshine'.
RHS show manager Kris Hulewicz said: "RHS Flower Show Tatton Park is known for its inclusive and supportive approach to gardening and landscape design. With all of these clever designs, as well as an array of allotments and Grow Your Own exhibits on display, we hope visitors will leave the show motivated to turn their own patch of grey Britain green."
