So I am creating a basic tavern floor plan map. I have never really added a grid inside my interior maps, just because I feel getting each room perfect (not having half squares against the walls and things) is really important. However If I add realistic wall thickness to the map. The walls would not be a full square thick. I want them to be thick enough I can add texture to the walls themselves. However if I make them realistic thickness, it almost forces me to use half squares or have different sized squares in the hall ways. How do you work around this issue? I don't want to randomly extend hallways to ensure the proportion is the same.

I hope this question makes sense. Its sort of hard to explain what I am asking.

Summary: I don't want to have a line of "half-squares" against a wall, and encompass wall thickness into the plan.

Any examples you could show me, would really help me out!

Thank you
