Hello!
In order to provide the players with a better experience of golf simulation, I have come up with the idea to stack the cubicles, as you proposed, in order to create an opening in between these cubicles and divide the land as public and private. The opening would be consist of a sliding door, allowing players to access the garden for a fresh breath, and enjoy the view while playing. Please read the descriptions below each render, as I added extra information to them.
Hope you like it!
Cheers : )
