Bungalow floor plan ~16x9.5m (outside) on 1000m² with existing old building

As planned, right. East as planned below (entrance), applies only to the floor plan. The 3D image - as 11ant noted - rotated 180 degrees

A friend who is an architect still has 2 floor plan variants (first proposals). For comparison, our favorite is variant 6

Whatever the sixth at four variants is supposed to be - have you ever mentioned before that a new access road is to be built from the West (I had so far assumed that one would go from the North past the shed)?

No. There will be no new access, and as you correctly understood, the path must go around the house. This would be accepted for a "perceived better orientation" of the rooms. I am aware that this involves additional costs. However, guests can be received via the access from the west or via the terrace.

I congratulate you on complete confusion and am off then.

No. There will be no new access road and as you correctly understood, the path has to go around the house. That would be accepted for a "subjectively better orientation" of the rooms.

Huh? I find the whole project so far completely chaotic, ill-conceived, and all the floor plans ugly and unsuitable. Sorry, I'm telling you this clearly as a friend who wants to help you. To me, it looks like a barracks set up as an emergency shelter, not like a dream house. Furthermore, important information about paths and supply lines is coming in only in dribs and drabs, and in the end, I no longer know where the garden gate for the postman is or where the cars are supposed to park? I think it would be very important for you to hire a real architect (not friendly amateur draftsmen). Under no circumstances should you bring your own designs—better just to name the number of rooms. Then have it done and come back with the result. I think every euro you invest in a professional is worth its weight in gold.
