Hello,
The plan is to carry out a full renovation of a single-family house that was probably built around 1900.
The ground floor has a 24cm (9.5 inches) brick wall (top picture),
and from the first floor upwards, there is an 11.5cm (4.5 inches) brick wall (bottom picture).
The house is timber-framed with bricks filling the spaces between the frame.
What would be the best insulation option in this case?
Or should no additional insulation be applied at all?

I will be removing more plaster next week to take a closer look…
I am not from the construction industry, so I can only describe what I have seen as a layperson.
Structural engineers and an architect will come soon to assess the situation.
Thanks to everyone anyway Here is another picture for those interested. Infill with clay mortar.
I hope it can stay like this and that it can be worked with.
