Why did the design turn out the way it is now? e.g.
Corresponding/which wishes were implemented by the architect

Very fancy house. With that budget, I would at least plan for a garage…

Hello Sunshine387, A garage was initially planned. However, we deliberately omitted it partly for cost reasons and partly due to a lack of discipline to keep it in order so that it can also be used for what it was made for.

Since we do not have a site plan yet, attached is a picture to better visualize the orientation. The house will be connected in the blue area, leaning against the neighbor with parcel 4162. Orientation towards the south.

Unfortunately, I cannot properly make out the floor plans, so I can't say anything about them. The views are great, just to my taste. For us, the second house also had a gable roof specified by the development plan, so I am always a bit jealous when I see such a design ;) Is the budget supposed to include [Pool and Spa-Bereich]? From my current experience, that might be tight.

Unfortunately, I cannot decipher the plans.

Nice house. I also see the budget as tight.
