The curtain wall measuring 25/260, which I have marked in the appendix, is located between the kitchen and the balcony. The project has started and now they are at normal floor level. The point I am having trouble with is the need for a door for the kitchen and balcony passage. How accurate would it be to open a 90 cm door? The basement floor curtains were torn in this way, but I have not seen such an application on the upper floors before. thank you in advance to those who are interested...
