For their first challenge, the designers were split into pairs. Their task was to create a living space in and around a single shipping container in four days and with a budget of $25,000.

Steven and Lisa's room was very well received, though they were chastised for going $4000 over budget. Dee and Leigh's room with a modular deck was praised, and Dee ultimately won the challenge. In the end, Craig & Jo, and Robert and Mary's rooms impressed the judges the least, but a dignified Craig paid the ultimate price for having an incompetent carpenter who could not complete the work he was assigned.

• Winner: Dee Tang
• Eliminated: Craig Voltz

During the challenge, Jo had to be taken to hospital after receiving an electric shock while cleaning the walls. Meanwhile, Dan constantly butted heads with Steve & Lisa over their design; his teammates feeling he became very defensive towards them. Despite this, their room was unanimously considered the best of the week, with Dan having the top design. Leigh, Jo and Mary had the least impressive design, which was considered too safe and boring by the judges, and it was Mary who was eliminated after the judges felt she contributed the least to their room.

This week's episode featured two different challenges. For the first challenge, the designers were split into teams in order to create a tranquil outdoor oasis atop a parking garage, based on one of the four elements. The outdoor rooms were also required to convey a sense of privacy.

During judging, Jamie stated that the quality of everyone's work was exceptionally high, making the elimination extremely tough. Robert won with his and Lisa's Mediterranean inspired garden, complete with overhead sails. Even though their bushfire-themed garden was well received, Leigh and Kai placed in the bottom two for not conveying a sense of privacy and tranquillity in their design. In the end, Leigh was eliminated, as the judges felt he focused too much on construction and not enough on design.

• Winner: Robert Davidov
• Eliminated: Leigh Mccrabb

The second challenge featured two parts. The designers were first tasked with individually designing a chair within a two-hour time frame. Dee's chair was voted the best, and she opted to work individually for the second part of the challenge. The rest of the designers were paired up and tasked with creating a room designed around one or both of the team members' chairs.

Throughout the challenge, Dan & Robert clashed on their design, opting to incorporate their own personal styles into their room. However, their quirky design was very well received, and Robert won his second challenge in a row. Jo & Kai's French boudoir felt too empty, and they were placed in the bottom two. The judges struggled to make a decision, and Kai was saved for her decision to create a raised dressing room in the centre of the space, thus sending Jo home in her third bottom two appearance.

• Winner: Robert Davidov
• Eliminated: Jo Bursill

Immediately after the last elimination, Jamie announced that three new designers would be joining the competition, much to everyone's dismay.{{citation needed|date=January 2023}} For their next challenge, the nine designers were split into three teams and challenged to create a high end, expensive hotel suite based around an international theme. Teams had three days and a budget of $50,000 for the challenge.

All contestants had various degrees of difficulty warming up to their new teammates, but none more so than Dan, who constantly clashed with Karl and his equally boisterous personality. On the other end of the scale, Robert felt that Dee and Chris were becoming too close and not pulling their own weight in the challenge. Despite this, the judges loved their New York-inspired room, and Robert won his third consecutive challenge. The French Provincial suite was the judges' least impressive, and Kai's dwindling performance in the competition sent her home.

• Winner: Robert Davidov
• Eliminated: Kai Ieraci

The remaining designers were first tasked with treating an item of furniture out of recycled objects. It was also announced that for winning the last challenge, Steve had won immunity this week. Once their pieces were finished it was then revealed that everyone would be working individually to create a room based around their creation, predominantly using recycled furniture.

The judges were very impressed with Dee, Chris and Steve, and both Chris and Steve had won the challenge as the judges could not settle for one outright winner. Robert was criticized for using far too much new material in his room, and he wound up in the bottom two. However, it was Dan who was eliminated for his unstable and incorrectly measured recycled table, and for being unable to properly finish and clear up his room within the time limit.

• Winner: Steve Trupp & Chris
