The House of Horrors site in Aranui has cost ratepayers $100,000.
The city council confirmed this week it had paid $50,000 for each of the two sections the infamous house and adjoining unit were on.
In 2009 the bodies of Rebecca Somerville and her neighbour Tisha Lowry were found under the floorboards of Jason Somerville's flat on the corner of Hampshire St and Wainoni Rd.
A city council spokeswoman said yesterday a process for what the site would be used for would begin sometime in the New Year.
Burwood-Pegasus Community Board member Tim Baker has said previously one option was it could be used for a children's playground. However, others in the community have slammed the idea and want it turned into a park.
