He said demolition would cost more than $3000, and he thought giving the house away would give someone a cheap first home instead of it going to waste.
"If somebody is interested, it's ok because if not I have to get rid of it anyway. I guess it's just for anybody who wants it for free pretty much.
"I tried to give it to removing places and they said they didn't have any space to take it because...they've got plenty of houses. This was the next best thing."
But the home had not been taking off online so far, Mr Adam said.
If he did not get an offer before the auction ends, on November 14, he would have to demolish the home, he said.
He had lived there for about 14 years and owns the dairy next door. The plan is to build a new home for his retirement as his health was already going a bit downhill, Mr Adam said.
"Even with it going for free, people are still demanding things, asking questions, saying it's a brick home. It is a brick home.
"I talked to the removal guys but I don't have any other land to put it on. You can take the bricks off, move it, and then put the bricks on or weatherboard on. To build a new house it might cost you $100,000 at least but putting weatherboards on will cost only $10,000."
The Trade Me auction page for the home has been viewed more than 5000 times.
It includes all the staples such as a kitchen, three bedrooms and a bathroom, as well as trimmings such as a stove and hot water cylinder, which would fetch a small profit at a demolition yard.
The home has a rateable value of $155,000 and the site and home package combined are worth $600,000.
A brick house is usually best left on its original site but can be relocated if all the bricks are taken off and it is later reclad on its new site.
The home is currently tenanted and appointments can be made for viewing.
