The House 4 pair won Kids' Bedroom and Redo Week on The Block with 30 out of 30, banking a $50,000 prize and extending a run that has made them the team everyone is watching.

Melbourne interior designer Chris Carroll told Chattr he saw them as the "best of a bad bunch", but thought several design choices kept the rooms short of perfection.

Chris Carroll Was Not Sold On The Kids' Room

Chris praised the wave-shaped bedhead, but felt it disappeared among the room's stronger colours and competing features. He also questioned the three bedside tables and said the timber and palette did not connect with the calmer style Courtney and Sev had established through the rest of House 4.

That is a very different verdict from the judges, who rewarded the room's adaptability and polished finish. The room reveal ended with Shaynna Blaze, Darren Palmer and Marty Fox all landing on a 10.

The redo also became part of the disagreement. Courtney and Sev added a fireplace and tinted mirror to their living area, but Chris argued the changes were "not enough of a redo" for a perfect score. He also found the fireplace placement awkward because of the way the sofa limited access to it.

Lisa And Rosco Were His Pick Of The Week

Chris preferred Lisa and Rosco's guest-bedroom redo, describing its new colours, furniture and styling as a much stronger transformation. Their kids' room also impressed the judges, but unfinished paint on the skirting boards cost them a perfect result and left them second on 29 points.

His review was less generous for the rest of the field. Adam and Jolene and Rick and Tayla tied on 21.5, while Chantel and Wyatt finished last on 17.5. Chris thought Adam and Jolene's redo replaced one unsuccessful look with another, and questioned why Chantel and Wyatt made only minimal changes after disagreeing with the judges' earlier feedback.

Courtney and Sev still have the only score that counts on the official leaderboard: 30 out of 30. Chris's take has simply given Blockheads another reason to argue over whether a perfect room needs to be beautiful, cohesive and dramatically transformed, or whether the judges were right to reward the finished result in front of them.
