Change of apartment layout plus extension

Then one of us doesn’t understand your planning:

Then I’ll enlighten you (and you already know: three golden hairs)

I think I am too tired for this thread,

I actually am too. But it’s so obvious. There can be no extension above the plan, as apparently only 5 meters of property are available there. Unfortunately, my program also cannot draw yellow and red walls, so: only the extension on the right side of the plan is expanded by about one meter, the interior walls shifted. On the left side of the plan, I have additionally marked the new walls in red.

Planoben geht kein Anbau, da dort anscheinend nur 5 Meter Grundstück zur Verfügung sind.

Good morning, thank you very much for your draft. That would be a great alternative if the extension is dropped for cost reasons. However, there is space for the extension at the top of the plan. A green area was purchased there a few years ago. This cannot be seen from the plans. Maybe you have another idea with the extension? It would be nice if you could go from the extension to the garden at the back, then you could make a terrace there. At the same time, it would also be good to get from the living room onto the balcony. Please keep in mind that an extension is only possible from about the old kitchen, as at the top of the plan, near the dining room, there is still a spiral staircase from the parents-in-law to the garden. Best regards

Calculate with 150k. Is that about 30 m2 of extension?

Yes, about 30m². How do you come to this amount? Best regards

I calculated 30*4000 euros and then another 30k for the renovation in the house.
