You know, I searched most of the texture sights listed for an hour or two, and then I had a thought. Regarding certain archetectural details, such as doors, windows and such, I simply did an internet search on those (seperately) and found enough door and window company sites and historical architecture sites that I not only found more than i could ever imagine using, I even found a photo with the near exact design of the door on my house (my first BAT I'm working on) Also, being Irish, let me recommend a search on doors of Dublin if you want some snazzy R$$$ doors for your buildings.
