This was only meant to be external. I should make a medieval interior pack. You'd have to implement a screen fade when entering buildings though.
Textures are down the road. Partial waiting for Assetforge to support custom textures.
Thanks man about MAST. It's about to get some major updates.
As far as the village kit, I will be releasing a new version sometime in the new few months. The walls will be 2-sided. It will include inside and outside props as well
