Internal highways in a condominiun

In Colombia, we call "conjunto cerrado" to a set of buildings or houses inside a barrier, with an only entrance area/door with a guardian. This could be called a condominium in English, but I wanted to explain before to prevent assumptions.

Well, those condominiums usually have internal highways that lead to parking spaces. I want to know how to exactly map them.

• These highways are just like residential highways, but we use to map as residential the public highways that have associated names/ref; because these internal highways are private we are thinking of something else.
• We also thought to tag them as living streets, but the same happens here. Living streets are public, with some legal stuff to call them like this, and the blue signal.
• Last option is service, and we are currently using this, but not really sure. The definition says these are for driveways, alleys, or parking, but none of the examples really fit in the definition of highways inside a "Conjunto cerrado".

There is a current discussion around this, and I would like to see what other mappers think or propose to standardize the mapping in Colombia. The examples proposed here also does not fit our issue.

Here is an example of those internal highways.
