The facade pattern is used when you want to hide an implementation or it is about changing interface of some class or set of classes. Builder hides the process of construction by decomposing it in smaller steps.

Abstract factory pattern is used when you want to hide the details on constructing instances.
Provide an interface for creating families of related or dependent objects without specifying their concrete classes.
