In my Hardcore World I´ve already built A Town Hall, A house, a Church and a Small Castle but what should I build next. You see, I build in a Medival Theme and I try to build a Village or even a City. Also, what yall think about my builds, what should I add to them?

I´ve built this in my hardcore world but I´m not very shure if the tower fits in.
Also I have no idea how I should decorate the inside.

Any tips?
