For 2023 winners Steph and Gian Ottavio, the most valuable part of their Block experience was not their $1.85m payday.
SJO Architects founder and Japandi Estate co-founder Steph Ottavio said appearing on the show had come at a pivotal point in the couple’s lives and changed what they believed they could achieve.
“For sure, I think what we learned on the show was invaluable,” Ms Ottavio said.
“It wasn’t about the prize money, it was about what we did on the show, and then what we thought we were capable of doing after.”
Steph and Gian Ottavio turned their renovation success on and off The Block into a serious property journey, with Steph saying the show changed the trajectory of their lives.
The couple had recently married when they decided to take on the television renovation, having already transformed their own home.
“We put our faith in the Block gods and put everything on the line to then see where our life could go,” Ms Ottavio said.
She said the experience “changed the trajectory of our lives”.
Ms Ottavio said contestants hoping to build lasting property or design careers from their television exposure also had to move quickly.
“There is a small window of time for you to capitalise on the opportunity that has just been given to you,” she said.
“We earned the right to be able to use our platform to create something more.”
Here are 10 standout property transformations involving some of The Block’s best-known alumni.
