A mum built her children a tiny fairy house in their bedroom wall - and leaves the little ones stunned by secretly replying to the letters they write using a hidden door.

Jo Brown created the tiny abode inside the wall between her walk-in wardrobe and her children's bedroom when they first moved into the house in Maidstone, Kent.

The children can access it from their room, but the 29-year-old also installed an entrance from her wardrobe without them knowing so she can leave them notes and rearrange the room to keep the magic alive.

The mum-of-three, who runs her own printing business, changes the theme of the house to celebrate different occasions throughout the year, leaving Grace, eight, George, two, and Louis, one, believing the fairies have visited while they slept.

Jo said: "My daughter is obsessed with fairies and all things fantasy so I thought it would be sweet to create a little fairy house for her.

"The kids visit the fairies once a week and see what they're doing in there. I move them around and redecorate the house for the kids' birthdays, Halloween, Easter and Christmas.

"There's even a little light that I can turn on from my side. The kids go wild when they see it and say 'oh my god mummy the fairies are home'.

"They write little letters to the fairies and I go in and pick them up and write replies while they're sleeping.

"They love checking to see if they've got any letters back."

Jo began designing the house while having her walk-in wardrobe renovated and roped in partner Jordan Park to create it using spare bits of wood, sample wallpaper from B&Q and twigs from the back garden, before filling it with dolls house furniture costing no more than £20.

And thanks to the workmen fitting her wardrobe, the mum can access the house from a secret cupboard to turn on the lights and redecorate the rooms, including a lounge, kitchen, bathroom, and bedroom.

Jo explained: "In our last house we had a fairy door stuck to the skirting board but when we moved I realised the walk-in wardrobe was a great opportunity to do something even better.

"Last Christmas we put our elf on the shelf in the house and I try to change things around whenever the kids have lost a tooth so they know the fairies have been.

"The kids love it, it's really sweet."
