N.B. I am not doing Laravel development currently, so this will not receive much love in the near future - but will leave it here for historical purposes ...
A sandpit for playing around with DDD architecture options in Laravel 4.
Gives a basic folder structure as a suggested approach, along with simple integration of Doctrine ORM.
This is provided as a companion to some blog posts at

It is not intended to be production code, and will not be developed past its current form in the near future.
If you have put together a working architecture of Laravel 4, Doctrine and good DDD principles, let me know and I will put a link to it from here.
