An ordinary Welsh house with an extraordinary secret is opening its doors to the public for the day - such is the demand to see what it normally hides from public view.
From the front it looks like any normal four-bedroom home – but behind this house lies an incredible Asian paradise.
Hidden firmly behind their traditional four-bedroom home, Don and Ann Knight have spent tens of thousands of pounds on their back garden boasting everything from a 5ft deep Koi pond to a Japanense Torri gate, pagoda and Amazon waterfall.
That's as well as the dozens of hand-pruned bonzai plants and perfectly manicured garden that takes the couple hours every day to tend and perfect.

And now for six hours only visitors will be able to visit this slice of Japan in the middle of South Wales.
Ann, 62, said: "I met Don eight years ago. He bought me the pagoda for my first Christmas present and it went from there.
"When I said you can do what you want to the garden I didn't expect this!"
For former Shell worker Don, gardening has been a life-long fascination since his first attempt at growing a bonsai at 12 years old.
But while every inch of the Llantwit Major garden has been transformed into an oriental haven, the 79-year-old has no plans to slow down.
Grandmother-of-one Ann said: "He's always in the garden. If it's raining he's like a caged animal - he hates it.
"The bonsais need watering twice a day once it gets warmer and that takes about an hour each time. As he's doing that he will spot something else that needs trimming or doing.

"I thought he had finished and couldn't do anything else and he watched Monty Don in Japan visiting the cherry blossom and then the autumn colours.
"He spotted something and proceeded to go out and buy these huge monolith stones for the garden.
"He also used the last part of the working garden for a zen area with white chipping. There's bamboo fencing across there to keep the dog off the white stuff.
"There's no more room to do anything else and I don't want to give him ideas!"

Every year the pair open their home to the public to raise money for Marie Curie, Macmillan Cancer Support and Hospice UK as part of the National Garden Scheme.
So far their record is 142 visitors in one day, as well as receiving private requests to visit their home.
Ann, a former bank worker, said: "The most in one day was 142 people in six hours which was a bit crazy.
"We've quite a few private visitors, there's been the bank pensioners, the WI, a koi club.
"One lady phoned up and asked if she could have her birthday party in our garden, she was 87.
"All the money they give us goes to Great Ormond Street Hospital."
With four children and six grandchildren between them, the garden has become a whole family affair.
While Don commands the back garden, with furniture made by Ann's son Alan, Ann takes full reign of the front garden to fill with her own flowers and plants.
She said: "Don's version of weeding is picking a weed and dropping it whereas I pull it out properly and put it in the green waste.
"I can't say I enjoy kneeling down in the earth but I like keeping a nice garden.
"We do sit and enjoy it with a cup of coffee."
