ALL-STARS Darren and Deanne Jolly continue their domination of The Block Triple Threat.

The Melbourne couple won tonight's week four room delivery on the renovation show thanks to a luxurious, fully-stocked wine cellar.

The four couples had to present three separate spaces tonight - a laundry, powder room and wine cellar - to judges Shaynna Blaze, Neale Whitaker and Darren Palmer.

Darren and Deanne, who also competed on The Block Glasshouse last year, were praised as the only team to install a laundry chute in their three-level apartment.

But it was their "champagne taste" wine cellar, stocked with 400 bottles of wine that won them the week despite a one-point penalty.

"It's absolutely beautiful," Shaynna said.

"It is quite warm in here but visually it's absolutely stunning."

The only thing missing was climate control, which nearly sealed the win for Adelaide couple Tim and Anastasia.

Josh and Charlotte are still yet to win a room after dominating the elimination rounds.

They tied for second place with Tim and Anastasia and cleverly saved money by filling wine bottles with coloured water to decorate their cellar.

Gold Coast parents Ayden and Jess came last with their uninspiring cellar, which Shaynna equated to a storage cabinet that lacked atmosphere. It's the third week in a row the couple has finished last behind the other three teams.

Darren and Deanne have won two weeks out of three as the first week they competed against the other all-star teams for a spot on the show.

The four couples will renovate their living and dining rooms this week.
