HMVC and admin pages

[eluser]gh0st[/eluser]
Its been a while since I've used HMVC and CodeIgniter. I am wondering when it comes to building admin pages, where do they go?

Should admin be a standalone module , or do you make folders within each module (ie: blog would have an admin folder)?

Lets assume I have a blog, and I need an admin panel for the blog.

Modules >
Blog
> Controllers
> Models
> Views

Do I put the admin folder in the controllers folder, wouldn't I also need a folder for the view folder too?

Thanks
