The three-bedroom house in Mount Nicholas Ave was listed this week at $995,000.
Parenting Place chief executive Greg Fleming said Covid-19 had put financial pressure on charities and the house was "an incredibly generous gift" from the building company.
The build was undertaken by Sentinel Homes Wanaka director Bob Howden with the help of local businesses, which gave time, money and resources.
Mr Fleming said the proceeds of the sale would allow 300 New Zealand families to access Parenting Place’s six-week "Toolbox" course for free.
The course covers practical strategies and insights to better equip parents of toddlers, young children, or teenagers.
"We come across so many parents who are feeling stuck and need new ideas to help them with the challenges of parenting.
"No two children are the same and the Toolbox courses are designed to help parents regain their confidence and passion for parenting by giving them new activities and strategies to use at home,” Mr Fleming said.
The house is the fourth Sentinel Homes has built across the country to raise funds for Parenting Place.
