TRIXIE from The Block Sky High will feature in a special live chat on The Observer website from noon today.

Months of efforts on Channel 9/WIN's renovation are about to go under the hammer this weekend so there's plenty of tension - and plenty to talk about.

The renovation show's five teams will go head to head on Sunday when their luxury South Melbourne apartments are sold at auction.

Whichever team pockets the highest profit will be named this year's winners in the two-hour grand final.

Queenslanders Trixie and Johnno's penthouse apartment boast's the best views but they are no certain winners.

Join APN's Chat with Trixie from The Block Sky High online at noon in Editor's Picks on The Observer website.
