a nano note

 The house with rooms that shift is on the property where the archives are, and that's the house that Josie stays in while she works on her project. I was going to make her live awhile away, but I like the idea of the house being relevant to the plot, even years later, and I like the idea of Josie living in it. 

Perhaps the government discovered the house, and when they noticed it was Strange, they built their archives near to it. I will think more on it when it it's not 2 am.
