Can I cut this and sleep well?

Seeing the entire drawing always facilitates interpretation. Some observations: The dashed lines likely indicate the footings on which the basement walls stand. In the ceiling of all rooms in the basement except the boiler room, there are steel beams (INP 16, 160 mm high. Closest corresponds to HEA 140). These are marked with dash-dotted lines. I see no explanation for why the slab above the boiler room lacks steel beams. The steel beams can either replace the reinforcement in cast slabs or serve as support for wooden beams. If the basement walls are masonry (i.e., not cast), it is likely concrete stone or concrete hollow stone. The width measurements do not match brick.

Thanks for the review, yes, that the dashed lines indicate the footings sounds very likely!

The thing about the beams was interesting, and this is confirmed as I can see in the ceiling of the laundry room where they are visible between cast concrete (concrete ceiling in that room).

The insides of the outer basement walls are clearly built up of bricks, which you can see here and there where the plaster has come off - and where the wall is sawed through for pipes to the old oil tank, I also see bricks deeper into the hole. This is not common, is it? No idea why it's like that - however, the interior walls are, as mentioned, cast concrete.

It's strange that just the boiler room's ceiling lacks vertical beams; today, as stated, there's instead a single visible, exposed beam, which is instead horizontal.

I just thought that the boiler room initially might only have been meant for heating tap water, not for central heating, as the house had tiled stoves and fireplaces before the radiators came in.

What is the thickness of the exterior brick walls?

What is the thickness of the exterior walls with bricks?

The wall is 52 cm thick. I'll correct myself when I say that I see it is solid brick - I can't see deeply enough into the hole to confirm that's the case. However, it's clear that the base exterior wall is brick-lined on the inside, with horizontal over-plastered stones, except where the stairwell is - that outer corner is cast.

What do you interpret the two horizontal, broken wall-like formations in the boiler room as? Are these now demolished walls? If so, walls that perhaps were load-bearing and provided the ceiling with the support needed in the absence of the vertical beams we see in the other rooms?
The upper of these "walls" has some form of marking on the far left where it appears to read " -0.15 ",

It seems like the bricks are placed with the long side against the wall. It probably was added later, except in what was the pantry. There is something included in the drawing there. The load-bearing element in the basement walls is not brick, I'm fairly sure of that. The wall-like formations in the boiler room lack footings, which makes me a bit puzzled. -0.15 could be a depression in the floor.

 

[Lärospånet]

There, you said something - they have no sole no ... And to be load-bearing, they should have had it just like all the other interior walls down there.

Aha, -15 can therefore mean that it's a negative number - a depression ... Interesting! There is actually an old pipe in the floor along the same line, but only visible in one spot a bit further to the right where it is not covered, which I have not understood ...

It seems like the brick is laid with the long side against the wall. It probably was added later, except in what was the pantry. There is something on the drawing there. The load-bearing element in the basement walls is not brick, I'm quite sure of that. The wall-like formations in the boiler room lack footings, which makes me a bit puzzled. -0.15 could be a depression in the floor.

It must be exactly as you say that the foundation wall is cast, but with an interior layer of brick. Why was it done like that?

Another thing that caught my attention was the lack of accessibility to the room in question on the original drawing. The drawing has windows and doors, but none that lead into the boiler room? There should be a door either from the inside or the outside, as well as a loading door for wood and coal if the door is on the inside... Could there be an additional drawing of that room somewhere? Is the doorway from the laundry room original?

 

[justusandersson]

The brick is probably primarily a heat insulator. There wasn't much available at that time. Few things conduct cold as well as concrete.

Yes, it is strange that the room lacks an entryway. Maybe it was a secret room initially?

The actual room also has two windows, which are not drawn. Is the door original? I don't know—but I do see that it differs slightly from the other doors down there; it is a bit lower so that a row of bricks fits above it, while the others go all the way up to the ceiling.

Regarding the loading of wood and coke, it seems to have been done directly through one of the windows. You can see how the frame is significantly worn at the bottom of that window, as if loads of wood pieces being loaded have worn down the wood...

That sounds reasonable!

 

[VidarH]

With original, I thought there were the same casting mold marks in the opening as on the walls. It's a bit exciting that they "forgot" to place a door and two windows otherwise. But one could have opened a door later, but it's less likely if there are also two windows.

 

[Lärospånet]

Well, the doors are embedded in brick interior walls, so there are no casting form marks there. But that particular door is a bit lower than the others. Yes, it's strange that the room was designed completely without doors and windows.
