I agree with @JackRosenberg the whole task was set up to fail.
Given the premise is to create their own apartment, why do they need to be able to collaborate or understand catering/commercial premises? I assume they wanted an extra episode for the number of contestants and don't have enough rooms in the apartment but the criteria felt off to me.
Scandi/retro/eclectic is an odd brief and asking everyone to design their own section and then judge them on it, is going to make it really hard for it to be cohesive. What would probably work best from a design perspective is if one or more of them took a step back and made their section very plain so another one would sing but of course no one is going to want to do that when they're in danger of being eliminated!
Poor Rachel had the hardest task being expected to do all the walls and tie everything together. I'm so glad she wasn't penalised for that. I lived her little sofa corner at the back.
I actually like Justine- I loved the idea of memory tables for that venue. Although the seat height was a real problem.
Patrjcha gets the same criticism repeatedly- no clear idea/confused/rushed. I don't know why she's still here! I hated that she partially blocked the window which would surely have made the cafe dingy?
John irritates me but I can see he has good finish. The bedroom felt very small though, I was surprised he wasn't criticized more for filling it so much. I like his bathroom
Jamie's bar was great! Him or Rachel for the win
