Are there any new buildings planned now that we can upgrade to level 21?

I see we can now upgrade our buildings to level 21, are there any new buildings coming?

The single level upgrade doesn't really do much to keep the interest going in my opinion.
Its a good addition in my opinion eventually they will add level 22 etc
Cant see the options on my game

Its just more of the same, unless they add some new buildings or perks to the upgrades.
