The unofficial Housing Guide

[Phineus]

I've been wondering about the internal walls and floors - do we have to use the Rivera floor if we've bought a house in Limsa?

You are able to use any wall/floor style regardless of which neighborhood you are in. We have a house in Limsa and we used Oasis walls on the main floor and second floor, Glade walls in the basement, and glade floors on all 3 levels. You can do any combination you like.
