I think I see a bump out for a wood burning stove. Not sure if the chimney will exit over a short roof and then extend the full height exposed to outdoor temperature? I don't have a lot of experience with them, but I've read chimney's have trouble drawing when lighting when the main length is cold/outdoor temp relative to inside. I think I remember reading that if the chimney is indoor temperature they want to draw better when lighting. (warmer air in the chimney wanting to rise vs outside as opposed to a long stack of cold air wanting to sink into the house).
You already have experience so you probably know better than me and have it worked out anyway. Regardless very cool plan and I'm sure will be very nice when done!
Congrats on the retirement!
Never heard of that and I’ve built many true working masonry chimneys over the years. Not the prefab kits you see today. It’s is extremely hard to build one that doesn’t draw correct. Height above roof lines I believe has more bearing than anything. I’m not saying what you are saying is incorrect. Because I’m sure an engineer somewhere said. But remember most all disasters go back bad engineering somewhere
