This is four houses each one is a different element. Water, fire, air and earth. They each have the requirements for each elements job as well. The stairs might seem a bit odd because the seeds wouldn't fit so that was the only way I could do it but if you had a better one then feel free to replce it and tell me. Hope you enjoy!! #4immortalsisters #fourhouses. Also comes with free CowPlant seeds d^_^b - Headphones = D..................
