Understand and revise the 1955 floor plan

well, since I would like to digitally recreate the floor plan,

We are thinking about buying my grandma's house.

Then you take 10 minutes completely analog and measure the missing dimensions with a folding ruler. The position of the doors is also not indicated.

yes that would of course be my plan B :) But since the house is not just around the corner for me, I am already trying to accomplish a lot from a distance

Unfortunately, there is no scale here :/ but thanks anyway for the other info!

Most of the time it is 1:100, you can measure it on the plan. That should not be a problem for a draftsman.

I join Hanghaus. 1:100 or you calculate the scale
Whereby I would definitely measure
Perhaps the missing dimensions such as corridor length or stair location are visible in the ground floor plan.

Wall thicknesses have already been written by Nordanney

Whereas the 12cm wall in my opinion is not a real wall, but only part of a party wall, which would then be 24cm in total (semi-detached house?).

It is an end-terrace house.
Therefore, you might be right that the wall actually has 24.
