No room for a chimney?
Ever since I saw this fireplace on Apartment Therapy I've loved Bioalcohol fireplaces. There is no need for a chimney with the contained burn and the fireplace could go literally anywhere.
Check out this awesome porthole styled fireplace from Redwitz. It's called the Rondo. I can see it looking so cool in a very rustic space. Even repeated a couple times horizontally or covering a large expanse in a grid like pattern.
