The Sydney couple were the last to arrive at The Block HQ, but were given House 1 for the challenge.

This year for the House Decider, teams were asked to complete a kids' bedroom.

But the challenge came with a twist: each couple had to use their gift from Disney+ as the inspiration behind their room's design!

Steph and Gian were gifted a Buzz Lightyear doll from the Toy Story movies.

With her architect hat on, Steph was the first to knock down walls and get redesigning.

But will their "muted" palette and interpretation of a kids' room be enough?
