Hello!
I've been looking around the forum and haven't found answers to my questions!
I bought a row house from '82 whose foundation is directly on the ground.
Under the carpet/parquet, there is chipboard, foam plastic, and a moisture barrier.
I have a door opening in a 100 mm siporex wall that needs to be closed. And what I've read is that a non-moving material is preferred, as it doesn’t shift over time, meaning zero risk of cracks =)
Now to my questions:
How should I start? Do I need to consider the house foundation, or is it just a matter of putting a "blob" of mortar/glue directly on the foundation? I'm mainly thinking about moisture. (A note, under the wall itself it's probably mortar and some green plastic blocks, anyone know what that is?)
How should I finish when approaching the ceiling?
I plan to buy siporex blocks that I will then reinforce in the "frame."
Would love to see the pictures!
In one picture, there's a beam that was used as support for the subfloor. It lay on top of the moisture barrier.
THANK YOU!

I would have removed all the wood at the bottom of the opening and built up with lecablocks, or siporex as in your case. Not sure if it's necessary but I would probably have tried to drill and insert some reinforcement every third row into the existing walls on either side.
Assuming there's plaster on the walls outside the aerated concrete, I would have removed a few centimeters in a frame around and placed plaster mesh with overlap on the old wall around the entire opening and plastered, so I imagine there shouldn't be any cracking at the joints.
Use a lot of blocks and little mortar to reduce the effect of the mortar shrinking as it sets; you can also use expanding concrete, which doesn't actually expand but doesn't shrink significantly either.
