Welcome to Workshop. It's great to have you join the community. I hope you find plenty of great ideas and advice here and look forward to hearing about your projects and plans.
I also hope that some community members can give you some help with your balcony project. The following D.I.Y. video from Bunnings might also be a starting point.
Could you please tell us a bit more about what you want to do? Perhaps include some photos of your balcony?
