As well as those famously big cuffs, one thing interior designer and former Changing Rooms presenter Laurence Llewelyn-Bowen is fanatical about is wallpaper – and now he wants everyone to share his enthusiasm for patterned paper.

“Wallpaper is a fantasy; it takes ordinary flat walls into a 3D world of pattern colour and texture,” he muses.

“You can literally dissolve your living room and open up a vista of jungle plants or twittering birds or dangerous looking damask curlicues.

“It is in fact great for making small rooms look bigger because it has the ability to camouflage the corners and when our brains can't read where the corners of a room are then they assume the room is much, much bigger.”

Turn back the clock 20 years and wallpaper, says Laurence, was considered out of fashion – so he decided to do something about it.

“Wallpaper's really thriving now but 20 years ago it was a dirty word. So back then I decided to do something about it. Having found Graham and Brown to make it for me I listened to what they had to say - no big scale floral designs - and so did big scale floral designs which became a huge hit. And I've not really looked back since.”

His range with Graham & Brown is as you’d expect; flamboyant, romantic with a heavy dose of laidback luxe too – which should be used in abundance, he says.

“I'm a bit of a purist so I like wallpaper to bring every wall in a room alive. Papering one wall the 'feature wall' only really works when you use a strongish colour on the three walls that aren't painted. But come on, be brave and hit your living room nice and hard with the wallpaper stick,” says Laurence.

Speaking of how Laurence would decorate a room, any chance of a Changing Rooms reunion?

“Believe it or not, it's 21 years since Changing Rooms first aired. I'm forever being asked, like the cast of Friends, what's left of the Beatles or the Jamaican bobsleigh team whether we'll get back together.

“I'll never say 'never' but at the moment with The Apartment filmed in South East Asia, a massive makeover show for Channel Seven Australia, my House of Laurence stores continually opening in China and new projects in Singapore Malaysia and the Philippines I don't know when I'd find the time.

“Anyway perhaps it should come back with a younger cast; they could always give my job to my grandson Albion. He's definitely a chip off the old block and even at four months old wears the cuffs of his baby grow floppy."
