Can I have Laravel control only certain folders?

I am looked around and still can't figure it out. I want laravel to only control certain folders of a website. I have a new client where I plan to build out an admin section for them in an admin folder. They will not setup a sub domain for the admin section. I want to build this in Laravel 5. The current site is a normal php with no framework or cms. Then as a phase 2 I am going to be cleaning up their site and also will want to convert this over to laravel framework. I am hoping their is a fairly straight forward way to do the admin section right away with Laravel and then go folder by folder and convert over their existing site.
