Wood cabin stone fireplace build

Thanks to all the viewers for their comments and advices after the first version of the fireplace. I learnt a lot building it and after all your nice comments. I tried to rebuild this fireplace considering all the advices I could gather. Some of you guys commented that it didn t make any sense to build the fireplace outside the cabin. Well, there are some reasons for that. First, I have not enough space inside the cabin for such a block of stone and mud. Also, should I built it inside, I would have to make a hole to the shingle roof, and then I would have to waterproof that. Here, where the cabin is, rain is the major weather issue; it rains every three days on average (I m pretty amazed that the cabin is not rotten yet ). And second, here cold is not really and issue. Average minimum temperature from December to March are 78ºC. SO I m OK with the fireplace outside. Another popular comment has been that the fireplace was not firesafe as it was. Lot of you gays have been wo br, br,
