Michael and Suzanne Nugent have let themselves in for every parent's nightmare - having teenagers run their home.

The Hartlepool couple have agreed to let their children Nathan, 16, and Tobias, 12, redesign their home for the TV cameras.

The result - which is expected to include a Japanese minimalist garden in their living room - is to be revealed tonight in ITV's Home On Their Own, a DIY show that lets teenagers run riot with their dastardly decorating ideas in their parents' homes.

Each week the programme takes a couple of youngsters, gives them a blank cheque, a team of builders and carte blanche to change the family home.

Recent shows have seen the programme's resident inventor Jem Stansfield and designer Kerry Sewell turn people's bathrooms into jungles, bedrooms into winter wonderlands and kitchens into burger joints.

The Nugent's house is set to undergo one of the most outrageous transformations so far, with five tonnes of gravel being dumped in the living room to create a Japanese garden.

A spokeswoman for the show said: "Tonight's programme should be one of the best yet.

"Ordinarily I don't think the parents would have considered having a Japanese minimalist garden dumped in their lounge, but that's what the kids wanted.

"The whole idea of the show is to let the teenagers loose. No idea is too idiotic, no transformation too tricky and no makeover too mindboggling when our team put their heads together. But who knows what the parents will think."

* Home On Their Own is on ITV tonight at 8.30pm.
