The Block Glasshouse marketing begins in Prahran

The Block Glasshouse marketing has begun with Buxton's inviting private clients to an early September preview.

The High Street apartment is being offered through veteran The Block agent Karl Gillon.

No public marketing has commenced for the auctions that appear scheduled for October auction.

Nor have $2 million plus price hopes been confirmed.

Buxton estate agent Karl Gillon is set to take on his third sales televised Block auction marketing campaign in the latest The Block Glasshouse series.

He will be marketing the sale of contestants Maxine and Karstan’s Prahan apartment at 3/121-127 High Street.

He's previously auctioned Brad and Dale’s property on last year’s Fans Vs Faves series in the O'Grady Street, Albert Park warehouse.

He also sold contestants Brad and Lara’s property in 2012, achieving a winning price of $1.62 million in the South Melbourne terraces series.

In recent series contestants have taken to include their estate agent in the design planning stages to ensure the apartment matches the locality demographics.

Estate agent Anton Wongtrakun of Dingle Partners is also returning. Last year he handled twins Alisa and Lysandra’s Albert Park sale.

This time it is Chris and Jenna’s apartment at number 2.

The agent newbies are Matt White of Ray White Port Phillip selling Michael and Carlene’s property at number 3 and Andrew McCann of Jellis Craig Bennison Mackinnon with Simon and Shannon’s apartment at number 4.

The AFL premiership player Darren Jolly and his wife Deanne have gone with Biggin & Scott Richmond.

The High Street Block auctions are likely to take place in October.
