Okay so eventually I want to buy a plot and put a Carbuncle house on it. I've already got the stuff to make the house in my FC workshop, so my question is this:

Once I buy the plot, do I still need to buy one of the housing permits, and, if so, how does that work? Break it down for me step by step on how I get a plot of land with my Carbuncle house on it.

Thanks for your time!
