Geoff Reid, who recently helped raise almost $55,000 for brain cancer research, was diagnosed with an aggressive brain tumour two years ago, forcing him to re-mortgage his home to pay for costly medical bills and surgery.

Plasterer Andrew White took it upon himself to turn a kind thought into a life-changing reality.

"The local building community have rallied together to build Geoff and his family a house so he can auction it off and have some peace of mind among all the uncertainty going on in his life at the moment, making sure his family are looked after," Mr White said.

"We've got a lot of local tradies and their suppliers on board, all different types from concreters and tilers to painters and roofers."

So far, they have lodged a development application for a block of land on Boorooma's Kellerman Crescent, with hopes of completion by early next year.

"We will all pitch in to pay for the land with the help of donations too, and everyone involved will provide a lot of the materials and things, plus all of the builders' time," Mr White said.

Once completed, they're hoping to auction off the four-bedroom home in excess of $400,000.

Mr Reid, born and bred in Wagga, said he was humbled with the support.

"We never expected to see this happening to me [being diagnosed with cancer]," he said.

"It's great to see people willing to go as far as they are with this house project."

Mr Reid thanks Mr White and all involved, saying it would go a long way to raising awareness of brain cancer.

"He's been there all my life, and this project is all about awareness out there," Mr Reid said.

"The more people who know about it, the better because we believe there needs to be more funding."

For Mr White, it is about more than helping out a fellow tradie.

"Geoff has been in the industry for more than 30 years, he was only a kid when he started," he said.

"I've known him since he was just 15.

"He's not just a great worker but also a great friend, he always looked after all the builders he worked with, made sure they were happy, so this is a bit of a payback to that."
