Hello, it's been a while since I've posted on this forum, I hope you're all doing well. I'm trying to improve the house's heat retention, and an area of uninsulated heat loss is the bread oven. So I'm thinking of making a free-standing, non-permanent, nice-looking door for it, perhaps from oak. I don't think there ever was a door on it originally because I've found no fixings for hinges in the mortar. Has anyone seen such a thing? Were there ever such things as free-standing wooden bread oven doors? Picture attached of the opening as it is now. Thanks!
