Single-family house city villa 200 sqm 2 full floors

Tell me: are you fooling yourself with the furniture sizes? In the children's rooms you can clearly see that your cabinets have different depths. And when I calculate in the dressing room at the bottom right, a depth of 55 cm remains... raw construction dimension! Plaster and skirting board still have to be deducted. Please check this for yourself.
