Will buyers agree with the judges on The Block?

Monday's episode of The Block will show buyer's agent and The Block regular Frank Valentic guide his clients through the show's partially completed apartments.

Judges Shaynna Blaze, Neale Whitaker and Darren Palmer have shared their thoughts on "luxury" bathrooms, copper clad bedrooms, and unfinished rooms on The Block Glasshouse, but now it's time to hear from the people who really matter - potential buyers.

Viewers may remember buyer's agent - and Property Observer contributor - Frank Valentic from previous seasons of the show. The agent successfully bid on the most expensive property offered last season, securing Chantelle and Steve's apartment for $2.47 million.

It will be interesting to see if Valentic's clients agree with the judges. Last season, rookies Steve and Chantelle beat out the other teams, despite consistently receiving negative reviews from the judges.

Contestants Michael and Carlene will be hoping that the buyers like their apartment as much as the judges have - the couple has received high marks every week, and finally secured a win with their staircase, laundry and guest powder room.

The judges were fans of their light timber stairs, which contrasted with their dark blue wall. They were also praised for their sensible and safe staircase, with multiple landings and a hand rail (pictured below).

The laundry was a less family friendly affair - in a good way, according to the judges (pictured below). Shaynna called the powder room, with a bronze mirror, gold details and matte grey cabinetry, "sexy", full of "terrific details". Michael and Carlene received 28 out of 30 from the judges.

Former wunderkinds Chris and Jenna were not so lucky. The couple has well and truly fallen from grace, with the third week in a row of poor comments from the judges.

This week, they were slammed on everything from their planning to their materials. Their heavy black bannisters, yet another attempt to reference the structural details of their apartment, was derided by all three of the judges (pictured below).

Their laundry room and powder room was unanimously considered a failure, with an unfocussed and confusing array of materials: from small grey tiles with white grouting to glossy black laundry doors, via cheap white cabinetry (pictured below). They were awarded 20 points out of 30.

Maxine and Karstan, who had their confidence boosted by their first win last week, delivered a staircase that was deemed a little dated by the judges.

The glass bordered stairs, with no handrail, was called unsafe and impractical - and it wasn't redeemed by its looks (pictured below).

With black timber steps and backlit wine storage under the stairs that was coupled by a polished aluminium kickboard, the entire area looked positively '90s.

When it came to the couple's laundry and powder room (pictured below), Neale felt "wholly ambivalent". The judges agreed that the area probably won't upset any potential buyers, but was unlikely to wow them either. Max and Karstan received 23 points.

Brothers Simon and Shannon were back in everyone's good books this week, with a staircase that "plays as a piece of sculpture", according to Darren (pictured below). Neale noted the boys' "amazing sense of confidence".

In the powder room, they presented a wide variety of surfaces - with glazed penny rounds, glossy black cabinetry and matte grey tiles (pictured below). Shaynna said the combination was "balanced", though she certainly didn't think the same of Chris and Jenna's material overload. The boys fared a good deal better, with 27 out of 30.

Lastly, Darren and Deanne presented unfinished spaces after major setbacks with their staircase (pictured below). Darren Palmer had a wobbly attempt up the stairs but quickly retreated - though it seems Valentic's buyers are a little more fearless, with tonight's episode preview showing the buyers braving the ascent.

Though Darren and Deanne lost major points for failing to finish a room, they still received some compliments on their wall panelling and drying rack and earned 17 out of 30. Their laundry is pictured below.

This week, the teams will complete their kitchens.
