IT'S the show that sees desperate house-hunters enlist experts to find their dream home.

But Melbourne couple Jenny and Dallas weren't prepared to relinquish everything in the search on this week's episode of Buying Blind - and didn't hide their unhappiness at the results.

The parents of two had a budget of $700,000, with instructions to find a four-bedroom home with separate accommodation for Dallas' elderly father John.

Describing her style as "Scandi-coastal-boho", Jenny was very vocal about what she wanted for her new home.

"I love interior design, styling, I think I'm quite good at it and people have said to me, 'come stage my house,'" Jenny declared,

After meeting Buying Blind's interior design expert Shaynna Blaze, the two women quickly went head-to-head over Jenny's demands, with the Melbourne mum refusing to budge on one demand - no black.

Inspecting her current home, Shaynna pointed out that Jenny's look was maybe a bit too "trend based" and she wanted to challenge the couple's wishes.

"I would probably like to do things that will challenge this white, bright feeling, just to give you more of longevity to your interior," Shaynna said to Jenny's shock.

Jenny's design demands were mocked on Twitter, with viewers begging her to stop using the words "Scandi-coastal-boho".

In a risky move, Shaynna decided to defy Jenny's wish for no black in the new home, installing dark floorboards and window frames.

Jenny couldn't hide her annoyance as she inspected the floors, saying: "I'll deal with it later … It's here now. I can't do anything about it. Don't want to be ungrateful."

Fortunately the rest of the house went down a hit, with the couple declaring the rest of the house as living up to their "wildest dreams".

Buying Blind continues next Tuesday at 8.30pm on Channel 9.
