Woman's Day reports that Nine is quietly testing fresh faces and is interested in adding a younger "culture expert" who could speak to the next generation of home buyers.
The magazine's unnamed sources claim former Bachelor star Matty Johnson is one of the names in the mix after he appeared on the current season with his wife, Laura Byrne.
The sources believe Matty's humour and willingness to voice an opinion could bring a different perspective to the room-reveal debates, while helping the show connect with younger viewers.
Shaynna Blaze is reportedly in the strongest position among the current judges after more than a decade with the renovation series.
The report also makes an unverified claim that Shaynna has money invested in Cavalier Productions, the company behind The Block. Neither Shaynna, Nine nor Cavalier Productions has publicly confirmed that financial claim.
If Nine decides the panel has one property expert too many, the report suggests Darren Palmer and Marty Fox could face the greatest uncertainty. It also stresses that neither judge has done anything wrong and that the current panel gets along well.
Producers are reportedly looking for more contrasting opinions rather than personal conflict, giving viewers a broader debate about design, property and what younger families would actually buy.
Nine has not announced any changes to The Block judging panel, and Matty has not confirmed that he is joining the show.
Shaynna, Darren and Marty remain the judges, with no new panellists announced for 2027.
