The "have had" construction is the present perfect form of "to have". As with other verbs, the present perfect describes either an ongoing condition,
He has had that car since he was a teenager.
or a life experience:
In my life I have had many good dinners.
Adding "could" or "would" to this is no different from other uses of could (to describe potential) or would (to describe a hypothetical).
He would have had that car since he was a teenager, if he hadn't driven it into the lake last week.
In my life I could have had many good dinners, if I was a better cook.
It's not a common construction, and it's not important to use it. Usually these kind of sentences can be written using the simple past:
He had that car since he was a teenager
I had many good dinners in my life.
Remember that to use the past perfect of "to have", you have to start with an example that correctly uses that verb. For example:
That building has a good address.
That building has lots of tenants.
That building has ongoing construction.
Then you can change it to the present perfect:
That building has had a good address (but ...)
That building has had lots of tenants (but ...)
That building has had ongoing construction (but ...)
And then add could/would as appropriate.
That building would have had ongoing construction (if it wasn't raining).
