According to the floor area ratio, only 138 m² is possible - 2 floors - Help :)

In that respect: wait and see what Escroda says about it. He is the expert who can explain everything to you coherently :)

Oh God, are you sure you want to go there?

If only 1 children's room I would consider a gable roof

UPS did not finish

If only 1 children's room I would consider a gable roof or a staggered floor
The space requirement on the ground floor is larger
If it is really only GF 138, there is no room for terrace, balconies, projections etc

Yes, unfortunately that could only be 0.15 .. and, thanks ... now I have spotted the trees in the forest ;).

How is the house currently positioned on the property? Entrance to the east or to the south (as I would suspect based on the site plan and the drawn building shape)? Access definitely from the east?

So it is 0.15 after all - I didn't misread it after all
