I suspect you mean the two pictures of the garage. It has to do with the property boundary; more precisely, about 3cm on our side there is a fence that belongs to the neighboring property, a kindergarten. Long story short. We could not place the garage exactly on the boundary as originally planned; the kindergarten would have only allowed a temporary removal of the fence at our expense. Since the fence's foundations naturally take up additional space, the garage's floor plan had to be different from the original plan and in the end this is what resulted. I can’t tell you the exact details off the top of my head anymore. Our architect of course explained it to us. But I didn’t memorize it in detail.
