Sky high construction costs are taking a toll on builders' mental health.  

CoreLogic Cordell Construction Cost Index for the last quarter of 2021 shows a 6.2 percent increase. 

And there's a warning that figure could hit double digits.  

It comes as a recent study from Mates in Construction has shown the impact it's having on builders' mental health.  

Registered Master Builders' Association chief executive David Kelly told Mike Hosking it's all compounding. 

“43 percent of people in construction that responded said that their mental health has got worse, simply with the worry about being able to build and managing the cost increases.”
