The decision to sell comes as the couple prepares for retirement and a move closer to a suburb in Adelaide.
"The search was hard. We've had this space for such a long time, but we've found a property with that same feeling and less maintenance," Mr Powell said.
"We're so happy with the work we have done here."
He said the property would suit another couple or someone with an entrepreneurial spirit.
“A lot of the hard work has been done. You can put in a swimming pool and a shed,” Mr Powell said.
“The infrastructure is there and someone can enjoy it as a home or even return it to a business.”
