Sorry, we are getting a new kitchen installed, and I did the demolition, and then had to be around for the installer guy. Haven't had time to read the forum much lately. They wanted $8k JUST for the demolition!!! So I did it...
Great idea. I bet if you reached out to that guy and showed him photos he likely could customize a solution that would work with your balcony.
