The outside and inside of a building being out of scale is a very old problem in ESO and sometimes ES in general. But the choice of using the small lighthouse exterior model with the huge mage tower interior from High Isles is just ridiculously jarring. It's especially strange because they probably could have used the mage tower as the base, and then stuck the top part of the current smaller lighthouse model on top of it and it would have matched fairly well. Or just had a smaller interior. Too late to fix, obviously, but I really wish in the future house designers would be a little more realistic in their proportions and end the belief that bigger = always better.
