Judges left confused by "very strange" feature.

Omar and Oz were the only team to choose not to present a bedroom in Guest Bedroom Week.

Instead they delivered a second living room, hoping it will give them an advantage over the other houses when it comes to auction time.

"Expect the unexpected from us," Oz told cameras.

The boys hoped the judges would see that they are "thinking outside of the box".

Scroll to see what judges Shaynna Blaze, Neale Whitaker and Darren Palmer had to say about Omar and Oz's second living room.

After weeks of questions surrounding their budget, Omar and Oz kept their spending modest at $14,344.

But even still it was one of the higher amounts spent by the teams this week.

The judges were surprised to find a second living space, but quickly pointed out some of its shortcomings.

"The only thing is it can't be adapted to a bedroom in the future if you want to," Shaynna said.

"With those doors, with those cabinets, with that fireplace, it is what it is," Darren said.

"It's either going to be a home office or a sitting room."

By choosing to deliver a second living room and not a guest bedroom, the judges said the boys have made a "very definitive decision" to present their home as four-bedroom house.

With all the other houses marketing as five-bedroom homes, the judges weren't sure if it was the best choice.

Neale didn't understand the decision to create a second sitting space, especially considering he knew "there was a very generous work from home space" in the plans.

"That box has been well and truly ticked," he said.

"This home doesn't really need another home office."

"I think this is a mistake," Darren said.

Shaynna agreed, while Neale said it was a room "that shot itself in the foot."

For Neale the room lacked purpose and he said it didn't even feel like a second living room.

"This is really only a room in which you can come and watch a movie."

Even when the judges put the saleability of the room aside, they said the space "lacked identity and personality".

Neale felt the cabinetry was "bare".

"It's demonstrating that it's a kind of useless waste of space," he said.

The judges noted that the TV was quite close to the sofa.

But after trialling it out for herself, Shaynna said "it's not too bad".

While at first Shaynna said the size of the TV screen was "in your face" she eventually came around.

Darren said it was "cinematic" and having a TV that "gigantic" was "awesome".

Neale was "confused" by the styling of the room, especially all the bunnies floating around.

He didn't understand the need for them if it wasn't a kids' room.

"It's very strange," Neale sighed.

Neale was particularly spooked out by the "biggest bunny of all".

"That bunny is staring at me, it's giving me the evil eye," he noted.

Overall the judges didn't appear very impressed by the room, and found multiple faults that could be improved upon.

The judges also wondered why there were so many games in the room.

"Is this a games room as well?" Neale asked.

"It's sending out the weirdest mix of messages," Neale said of Omar and Oz's room.

"It's like throw everything at us and we can decide what room this is gonna be. But I'm afraid that doesn't work," Neale added.

The judges thought the room lacked cohesion and even the things they did like felt wrong – one being the wallpaper.

"It's not that I don't like the print, I think it's the wrong print for this house," Shaynna said.

If there was one positive, it's that judges noted how well executed Omar and Oz's space was.

But even so Shaynna thought the boys now had two re-do rooms to do.

"It doesn't add more to my perception of the value of this house," Darren said.
