Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Similar situation for me years ago...had redundancy money to build dream shed with hoist yet council wouldn't give approval even after going back & forth several times changing plans that still abided by council rules so gave up & made do with current crappy ol' garage.
Was roughly 30k which was baller spec triple setup....easily cost double that or more to build now.
@afstruct, my total was around $80k. Not sure on the exact figure as I'm afraid to add it up haha.
From memory that was all council paperwork, site plans, earthworks and concrete, shed kit & erection, electrical fit out, plumbing and flooring.
The polyaspartic flooring was a last minute addition ($4,680) and the plumbing was a little unexpected ($5,632), and I had issues with the switchboard which cost me a grand extra to sort out.
nd big fi
Minus that lot, probably could havotten away with it for around $70k. If you don't have another driveway to pour like I did, high $50k is the ballpark.
