how to set up texture's for next gen houses (current gen)

i am in the making of an RPG got alot of the scripting down and so forth, but i am stuck with buildings now :P what kind of workflow and ways to do it is tehre when fx, making a big building like a tavern, do i combine all the things and just texture it that way, or what kind of procedure would you guys recommend? thanks alot in advance!

You have to model buildings in 3d modeling software. such as Blender, Maya, 3DS Max, Houdini. And if you are satisfied with your model you need to UV unwrap it. save the UV's and use Photoshop or other software of that kind to texture it.
