Thanks!
You are very welcome. What do you mean with "lowerclass" and "upperclass"? What class do the meshes I already created belong to?
And yes, I think I'd like to create meshes for the city walls. As for the castle; don't you think my Seaview-meshes would be sufficient?
What do you have in mind for the city walls?
Well, the buildings mostly fit into middleclass, and I'd would call the ones with the red plaster on the top upperclass (as they look fancier), so what would be needed is just the lowerclass, more run down looking buildings, diritier, etc

(the 'class' being the state of the building, and relates the people living in it, the poorer the Npc is, the more shabby a house they'll be living in, the more wealthy they are, the more fancy a building they live in).
And great with the walls!

and in regards to the castle, we could get away with using the seaview meshes, however in Daggerfall, it actually had a uniquely modeled castle, of which we'd like to preserve as much as we can (while updating it ofcourse to suit Oblivion), and the same situation exists with the Wayrest Palace (which someone has already offered to model, but has taken quite a few months without progress).
So I'm thinking something like http://upload.wikimedia.org/wikipedia/commons/2/23/The_Town_Wall_of_Avila.jpg, http://fotos.euroresidentes.com/fotos/avila/images/avila%20(06).JPG, for the wall set, however as long as it looks medieval and unique from the stock wall set it'll still be excellent, you can get creative
