According to Detective Acting Superintendent Stuart Gordon, the house was likely being used as a “safe house” for the drugs.
Detective Acting Superintendent Gordon said the discovery would have been shocking for the plumber.
"No tradesman really anticipates going to work on any given day and tripping over hundreds of kilos of drug and cash, certainly a good story for some people to tell I'm sure," he said.
Police were called to the scene where they performed a thorough search of the apartment and a storage garage in the basement.
Police managed to uncover 15 cardboard boxes full of crystal meth, along with 95 grams of MDMA, 35 grams of cocaine, chemicals for the production of drugs and $1.15 million in cash found inside of a grocery bag.
According to Detective Acting Superintendent Gordon said the people storing the drugs are part of an organised crime circuit.
"220 kg of drug is a lot of drugs in anyone's language and when we're talking these quantities of drugs and cash you're looking at organised crime," he said.
"We would say people involved in organised crime and moving this quantity of drugs are a risk to the public every day of the week."
Police are currently searching for a man who they believe could assist with their investigation.
