Best practices for modelling this scenario [on hold]

I have a class that extends fos_user class from FOSUserBundle. Every user have some roles. If user has role "BASIC" he has a OneToMany relation with entity Entry (one basic user has many entries). If user has role "MASTER" he has a ManyToMany relation with entity House (many master users have many houses).

I done this:

/**
 * @ORM\Entity
 */
class User extends BaseUser
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @ORM\ManyToMany(targetEntity="House", inversedBy="users")
     */
    protected $houses;

    /**
     * @ORM\OneToMany(targetEntity="Entry", mappedBy="user")
     */
    protected $entries;

}  

But it doesn't sound fine.

Is there a design pattern for this scenario?
