That's it! But of course, we may ask contractor to provide 2 or 3 designs/materials for residents to choose.... may not be easy to get all residents who wish to convert to balcony to agree on a single common design.
By the way, I heard some condos actually provide "free" unlimited broadband internet access for all residents as part of their marketing strategy. Well, not exactly "free" as it is included as part of their condo management fee. We may ask if developer willing to conduct a survey for all RT owners to have this as an option?
If we can get things organised before TOP, we may achieve greater bargaining power as a group.
