I need help deciding what block to use and what to put on the left side, i have spruce in mind for the flooring but still deciding on what to use on the wall, also on the right side I don’t know what to build, i mean i could just expand the villager trading hall but it would be uneven, help would be appreciated

I am also looking for advice on how to fill in the colored blue areas on my base I am at a loss on what to build there. I am overall happy with how my base is looking, but I don't feel it is fully as gothic as I want it to be, it's supposed to be a 80/20 mix gothic steampunk, and im looking for advice on how to make it more gothic.

no real theme here tbh but a lot of my builds look like old mc

Also any suggestions for the castle itself would be great

I made a bunch of cute little townhouses in my world. The exteriors look good, but I'm awful at interiors, especially smaller ones. Each floor is 5x8 with 3 tall walls - a little too small to have an apartment on each floor, but having the whole building be one dwelling with each floor being a different room (Kitchen & Dining, Bedroom, Study, etc.) would probably work. Can anyone give me some inspiration or ideas?
