A moon temple?
A Pellitine jungle palace?
A bandaari camp in the desert of Anequina?
What are your expectations?
Also - more on the "worldbuilding" side - I'm wondering how much different or "discontinuous" the architecture of Elsweyr and Reapers' March+Khenarti's Roost will be.
There was quite a huge diffence between the buildings in Auridon (modern Auridon + Ayleid) and in Summerset (modern Alinor + ancient Aldmeri), which could make sense because of the divide between these islands.
But Elwseyr is literally between Dune and Mistral...
Same flaw can be noticed for Hew's Bane style that have little in common with Sentinel and Strom M'Kai although it is in-between.
I'm not saying they should have not created any new designs for newer zones, but perhaps they should re-use some buildings (on the borders in the new zones) of older models in order to keep the continuity of the world.
