Rain could not deter the enthusiasm of builders who began construction at the new Bower estate on Monday, where 100 per cent of the materials, labour, furniture and furnishings were donated.

All money raised will support childhood cancer which include children like three-year-old Nixon Ball and his family.

Nixon is a survivor of childhood cancer and his dad, Nick, who works with McDonlad Homes, is also helping with the build. 

A few weeks before Brodie was due to give birth to her third child, a scan showed a large lump on the baby’s head. Soon after its detection, Nixon was born with a tumor the size of an adult’s fist.

Biopsy surgery, which took five hours, was performed on Nixon when he was barely one week old. After a week of waiting, the family received the gut-wrenching news; Nixon had cancer and needed to immediately begin treatment. Nixon is now doing well.

The house will be completed for a reveal day on September 16 which will be followed by an auction on October 21. It is expected to fetch around $650,000.

On ‘reveal day’ Scott Cam will be joined by McCloy ambassador Mitchell Pearce, as well as a host of special guests including past contestants of The Block, children's cancer survivors and their families, medical researchers, architects, builders and interior designers.

Partnering McDonald Jones and the McCloy Group, who donated the land, are a number of local stakeholders and workers all donating their time and materials for the cause. 

Newcastle Knights players Mitchell Pearce, Nathan Ross, Shaun Kenny-Dowell and Daniel Saifiti attended the kick-off event on Monday.

The Children’s Cancer Institute is dedicated to research into the causes, prevention and cure of childhood cancer.
