Need suggestions for L house design

[Welsper59]

I bought an L house a while ago, but due to a lack of gil after (and spending on other things), it's been progressing slowly. My goal with the house is to make it into a themed attraction of sorts. The first of which is to make it Persona themed (particularly 3 and 4). Any suggestions on what I could/should do? Help with what housing items to use would also be welcome.

So far, I have the P3 Velvet Room (basement) and P4 classroom (second floor) more or less set up. I plan on using the remaining space of the basement for the P4 Velvet Room as well.

I was contemplating making the P4 kitchen/living room, reception area of the P3 dorm, and the Junes foodcourt area outside soon. Not sure what else to make that would be possible with current furniture available. If anyone is interested in checking out what it currently looks like, I'm on Leviathan : The Goblet ward 7 #5. Keep in mind that it's still very much a work in progress.

Uploaded some pics. Unfortunately, I'm at work and on my Surface Pro, so quality isn't going to look very good.
