'I love it already' ... Lisa and Adam were thrilled with the renovation.

Just when you might have had House Rules' Adam pegged as a cool as a cucumber kind of guy, he busts out a hooley dooley or three.

Adam and Lisa were overwhelmed by the transformation of their 1960s "old lady" cottage in suburban Melbourne in the third renovation on the Seven's reality show.

Six teams take turns having their homes made over by the remaining House Rules couples, with the pair on the bottom of the leader board eliminated after the last renovation.

Victorians Adam and Lisa.

"Hooley dooley," Adam gasped, as he walked through the entrance and into the kitchen.

"I love it already," Lisa said, bursting into tears.

A cleverly designed kitchen and entrance by South Australians Bomber and Mel was enough to edge out Queenslanders Maddi and Lloyd by one point.

But despite being off the mark with their main bedroom styling and ensuite design, the Queenslanders did well enough to remain on top of the overall leader board.

Designer and judge Joe Snell branded Maddi and Lloyd's central ensuite vanity with statement tiling one of the smartest ideas ever executed on the show.

But their draping of material from the master bedroom ceiling, in a bid to follow the moody boudoir house rule, wasn't so well received.

"I feel like I have walked into a circus tent," judge and Home Beautiful magazine editor Wendy Moore said.

Adam and Lisa said perhaps they should have done more research into how the term boudoir could be interpreted.

"I don't know if I come across as a princess on TV but I'm definitely not a princess so I don't feel right lying in there," Adam said.

The toilets in both the ensuite and main bathrooms were the real stinkers this week.

Adam and Lisa and the judges were far from impressed that people on the street could see the ensuite toilet if the blinds were open.

"The last thing you want to see when you are on the throne is people on the street and you don't want them to see you," Moore said.

West Australians Carole and Russell decided to enclose the toilet in the main bathroom with frosted glass.

"That little room is a little smell catcher," Mel said.

"It would be like going to the toilet on an aeroplane," Bomber added.

Moore said the toilet cubical reminded her of a confinement cell while Snell described it as a translucent fishbowl.

"Yes, you could see a silhouette of someone sitting on the toilet but you can't see his private bits," Carole protested.

Lisa loves the loud tiles in the bathroom while Adam said the design was growing on him.

"But I think the wallpaper in the dining room might have to be changed in time," Adam said.

Despite finishing equal last with Carole and Russell, Tasmanians Brooke and Grant escaped camping out in a tent because their home is the next to be renovated.
