Facade goes inside in each package or must have a package only for facades?

Where the Facade classes must go? Supposing I have three packages, Facade A goes inside Package A, Facade B goes inside Package B and Facade C goes inside Package C or I need a separate package only for Facades?

What is more recommended?

I'm using the first solution, but I think is not right. Some classes are using a facade that allocates some objects that the class not uses.

Solution

It really depends on how your packages are organized.

Suppose you have payment, hr and contacts packages, then it would make sense to have a façade for each of them.

If you split your package in a less domain driven way, like for example services, dao and web then making a facade only for the service layer would make sense.
