Hello everyone,
the shell construction has just been completed for us. Then the boss of the Polish window company came and measured all window openings (shell construction dimensions) and created the final offer based on that. Before that, he made a rough preliminary offer based on the architect's drawing, using the drawing dimensions. Afterwards, we went to his office and he presented and demonstrated the windows and shutters live on a demo wall.
The installation will then be carried out for us in variant 1.
