Campbelltown family's rebuilt home unveiled on House Rules: Photos

"For everyone to go out of their way and do this for us, it means a lot for us and the family."

That's the message from Campbelltown's Graeme McPake after his new-look home was unveiled on Channel Seven program House Rules on Sunday night.

The father-of-four's home was completely destroyed by fire last November.

The blaze is understood to have started in the roof. No-one was home at the time.

House Rules contestants stepped into rebuild the house, including a renovated lounge room, master bedroom, bathroom and kitchen.

Mr McPake, his partner Mary and children Lily (10), Skye (seven), Cole (two) and Jade (one) featured on Sunday night's episode, where the home's final look was unveiled.

Mr McPake said the new home's look was amazing and he thanked the House Rules contestants for rebuilding his home.

"Without House Rules, I don't where we'd be right now," he said.

"The contestants were really sympathetic. They put aside the fact that this is a competition and listened to our story.

"I don't know how to pay them back."

Without House Rules, I don't where we'd be right now.

Mr McPake said the family did not have insurance when fire destroyed his home.

"We were on our own. That was when it really sank in - we're in trouble," he said.

"It was an extremely tough time for us."

Mr McPake said the House Rules opportunity "fell out of the sky".

"I used to turn up at the house every day, just to do things like sweep the floors because it felt like I was doing something positive," he said.

"I then got a call from one day from Channel Seven asking if we were interested to appear on House Rules."

Mr McPake said the terrible incident had produced a silver lining.

"To have my family together supersedes everything, it's the biggest blessing," he said.
