What mod is that underwater building from?
there are two mods of it and i use both:
http://planetelderscrolls.gamespy.com/View.php?view=Mods.Detail&id=7610 is the complete model, that i use for the exterior (it contains a whole mesh for in- and exterior).
http://abot.silgrad.com/guppy/articles.php?lng=en&pg=108 is a tileset, that dissambles the whole model in single parts. this one i use for interior, also because the original has texturing errors in it.
the furniture on the third pic i retextured myself. no chance to release it, i have the texes from the web. maybe i can find some shell and mother-of-pearl objects to make photos by myself.
