Displaying posts differently on different pages

I have a custom post type which needs to be displayed differently on two sides of my site.

Firstly, a public side- mywebsite/cpt/post – this is fine.
Now I need to display this same post on a ‘Pro User’ side – mywebsite/pro/cpt/post – preferably even- mywebsite/pro/*username*/cpt/post

This will need show various data and information that isn’t shown on the public side and with a sub menu/tabs to show this data across more than one ‘page’. I know posts aren’t hierarchical so this is also a challenge to overcome. One of the pages will be a font end editor for the post using Gravity forms and a couple of addons.

Now I have created a loop of the posts that display on the pro home page based on the current user but really struggling with changing how the post is displayed once they click on one, as it just shows as it would on the public side.

Hopefully it’s possible and If anyone can point me in the right direction that would be great.
