Update (1): Furniture

Update v1.1

I've added some new stuff to the rooms like chairs, tables, and rugs in this update. Next time, I'll throw in more decorations like flower pots, lamps, and paintings.

By the way, I've tidied up the folder structure of the packs to make things more organized. I'll try not to mess with the file setup too much, but as the project gets bigger, there might be some changes.
