How to serve / view other files outside htdocs?

I have a standard setup usign apache2.4 where I create virtuals. This works fine. I need to be able to serve / somehow browse files that are not (and can not) live in the htdocs folder. How do I add a site that lets me browse the www folder itself so I can navigate that way?

Replying to my own post here, because I came up with using regular old php which is installed easy enough, and using php -S at the current working dir. This is a fine enough workaround for my workflow.
