I'd go for a higher ceiling on a larger built structure rather than a chimney on a smaller house. Or both a high ceiling & a lowered ''recessed'' fire pit to match. I typically build medium to larger structures as I find it easier to have more storage & vent smoke easier, usually.

When you have a roof that is high up past a certain point, you don't need to put a chimney, as the smoke seems to just raise up to a certain point, linger, & dissipate. Where as inside a smaller, lower roofed structure, you would need a chimney to let the smoke vent...

If I remember I'll chuck some screenshots up later so you can see what it might look like to give you an idea.
