HAVE BEEN is used in the present perfect continuous tense.

I have been watching TV

You have been at the park since midday.

He has been busy all day.

We always have been living at this address.

The present perfect form of the verb "to be" is "have been" (or "has been").

Yes, you can use it for the present perfect continuous, as you have in I have been watching TV for four solid hours, but you don't have to use it with a continuous form. I have been busy. You have been at the park since midday. These are both present perfect. There is no continuous here.

As an American, I would never say "We always have been living at this address." I'd say "We've always lived at this address." I wonder if BrE is that different.
