“It’s an obvious no-brainer.”

The Block 2025 winner will be determined by a live auction, but former winners Steph and Gian Ottavio already know which house will sell for the most money.

On Shelley Craft’s official The Block podcast, Steph and Gian joined her to chat about the show, and the couple weren’t shy about which house they would have chosen if they were contestants this year.

“Absolutely [House] 5. There is no other option,” Steph said, before Gian agreed, saying he thought House 5 was “the best”.

Steph is an architect, so she had some thoughts about the layout of The Block and tipped Robby and Mat as the future winners for 2025.

“I personally know the house that is going to win before anyone did anything to it. From the orientation,” Steph claimed. “You’ve got five houses, all with the same floor plan. The one on the end that overlooks the national park so that no one can obstruct your view, naturally, then would have the best sunlight and the way in which the sun hits that space and just the landscaping, the portals and everything, that’s created by not having a neighbour on one side, it’s an obvious no-brainer.”

Steph stressed her choice wasn’t based on any of the contestants or who she liked the most from her visit to site, but because of the bones of the houses.

“The way we look at property is the things that you cannot change and you can’t change the site conditions and that is why House 5 will win,” she added.

What does Gian like about Robby and Mat’s House 5?

Gian also picked Robby and Mat to take away the grand prize, because they are “thinking outside the box”.

“They were gonna have an added amenity in that wine cellar, that if 100 people were walking through five houses, that was the one that would stick in their heads, because no one else has utilised the space like that,” he told Shelley.

However, Emma and Ben decided to add a “wine storage room” below their house, which kicked off a whole cheating scandal.

“I think copying is the biggest form of flattery. I don’t believe in copying. If you see someone is doing something exceptional, be better, be faster, be more creative. Do something to one-up that. Don’t just try and do an inferior version of it,” Mat told Chattr.

At least Robby and Mat have Steph and Gian’s stamp of approval, whether or not there’s a copycat on The Block.
