This year's season of The Block is set to be the Blockheads' biggest project yet.

If you're a devoted fan of the popular reality renovation series, chances are you've been restlessly wondering: when The Block will be back on our screens in 2019? Well, you can stop wondering because Channel 9 have confirmed that The Block will officially return to our screens for a 15th season on Sunday, August 4, at 7pm. Filming of this year's seasons actually started way back on Monday the 25th of February which means The Block 2019 contestants have been renovating tirelessly for months now, transforming the neglected Oslo Hotel in St Kilda into five high-end, three-storey homes. Here's what we know about the progress of The Block 2019 so far...

KITCHEN WEEK HAS BEEN COMPLETED

Behind the scaffolding and general chaos surrounding The Oslo Hotel are five beautiful, shiny new kitchens. Last year, many new kitchen design trends were on show from metallic cabinetry to open-ended butler's pantries, top-of-the-range fridges and more. We can't wait to see what the Blockheads will come up with this year! Judge Neale Whitaker recently unveiled his newly renovated kitchen which he calls his "dream kitchen." We hope the contestants have taken notes for some extra kitchen design brownie points.

THE CHARITY CHALLENGE HAS BEEN FILMED

Last month, the contestants were spotted at the Trevor Barker Foundation apartments in Torquay. Usually, the charity challenge takes place mid-way through the competition, so we know (gauging by last year's timeline) that at least half of the townhouse should be complete.

THE BLOCKHEADS ARE BEING THRIFTY

Judge Shaynna Blaze told The Herald Sun that each team has only a budget of $220,000. That's a tight squeeze considering these townhouses are the biggest in Block history. While Shaynna is predicting a few unfinished rooms this season, it looks like the Blockheads are really knuckling down and trying to save every last penny. One Block car was even spotted parked outside of Vinnies.
