So you are now doing a deep excavation and only using the excavation pit, although OKKD would have also fit height-wise?
No, on the one hand it's completely normal that there are no ceiling plans (and never were). On the other hand, something would only be present by chance, because a house from around 1920 has after all already survived the Second World War. More archives were bombed than Napoleon once said that stuff from the Caesar era could now be shredded ;-)
In the Middle Ages there was still a lot of chaos and the urban settlement form was still new; the main driver of building regulation evolution were devastating fires. The first development plans aimed at combating frayed street edges by specifying building lines – development plans were therefore still very straightforward: there was a building line on the street side, and the ridge height requirement "not higher than the church tower." Even during the imperial era there were few regulations: for example, in Berlin there was the eaves height regulation measured by the idea that a house facade, hypothetically collapsing like a felled tree, should fall before the row of houses opposite, and in the inner courtyards the turning circle of the fire engine was the measure of all things. Demanding structural calculations for a building application is rather recent and there are no irons in wooden beam ceilings anyway.
Wooden beam ceilings are very friendly to building forensics, but in this case that only concerns the one between the attic and the roof space, whereas the ceiling in question that needs clarification is the one between the ground floor and the attic.
WE have not made any progress yet, as long as you do not share the development plan with us. So far, nothing has been proposed that seemed unfeasible to me (with four decades of experience in this stuff). By the way, the current house IS single-story, since sticking a shipping container with a flat roof to the house does not seem appropriate to me.We have made quite a bit of progress now, as we were with the draftswoman in the house, and she brought the development plan. So the roof shape is settled. It must not be built differently.
Why bother if you don’t accept the criticism and again draw such nonsense with a partially chewed-up existing exterior wall? - as long as steel isn’t playing Rolex, almost everything is structurally possible, then there’s just no money left for anything else ;-) With what kid’s program are you even trying your floor plan tinkering? It’s almost an art to sketch proportions whose correct measurements you know so cavalierly! For us readers it’s "just" exhausting, but for you it greatly costs potential clarity :-(New plan here: I have marked in gray the walls where a breakthrough would have to be made. Do you think that's structurally feasible? [...] Feel free to be completely open. Any kind of criticism helps me
WE are not any further as long as you don't share the development plan with us. So far, nothing has been proposed that seemed unfeasible to me (with four decades of experience in this stuff). By the way, the current house IS single-story, as sticking a shipping container with a flat roof onto the house does not seem appropriate to me.
Why, if you don't accept the criticism and draw such nonsense again with a previously thinly nibbled exterior wall? - if steel doesn't pretend to be a Rolex, almost everything is statically possible, then there just isn't any money left for everything else ;-)
With which beginner program are you even trying your floor plan tinkering? It's almost an art to roughly copy proportions whose correct measurements you know so carelessly! For us readers, this is "just" exhausting, but for you, it crucially costs possible clarity :-(
