I don't think putting a door in a doorframe that used to have a door would count as structural changes but I don't know anything about anything at all.
Damn your chalkboard drawings are so neat O_O
I want one of those in my house, we could use an extra bookshelf XD Even got a doorframe to put one in though we took the door that was in it out for reasons and I can see more accidents happening if we put a heavier one there x_x
I wasn't allowed to change even the door frame except for a couple of screws. It is nice that it could easily be removed if it became a danger.
Thank you for crediting my chalkboard drawing. It required a lot of skill.
Luckily the wall was solid stone and quite thick. I don't think you would get away with this in a modern house.
My house is far from modern (built in the late 1890s, extended in the 70s?) and I don't think it would survive this XD (it's brick veneer x_x)
Wow, cool to live in such an old house. Over here it would be a big worry for heating bills. I just spent the last two years trying to make our 1950s house warm. Insulation and big stove. More to do this summer.
Fortunately it doesn't get so cold here, otherwise that would definitely be a problem! Earlier this year we finally had the funds to put reverse cycle aircons in the kids bedrooms, poor things have been suffering for years in rooms that are hot in summer and cold in winter (summer was always the bigger problem as there was no relief especially after losing two shade trees, winter sucked but they don't yet have long term injuries which act up when it's too cold and always hurt even when you have the blankets and things piled on to keep you warm).
Is it at least a little bit warmer with the work you've done so far?
