Arrangement of a single-family house on a small trapezoidal plot

Are there no details about building heights? Reference points? Reference heights?

Yes. But hillside details in combination with House A, B, or C. And with all due respect for tinkering, it's too much for me to summarize all necessary information, including maximum eaves heights, clearly and to determine for someone else, whose floor plan I don't know, how the house optimally stands within the fixed dimensions. Those are the homeowner’s tasks. Also, to work out the facts.

It does make a difference whether I place the house centrally

Yes, but are we talking about one meter to the left or right or ensuring the living room gets enough light?! The floor plan is truly the real challenge here – now comes the hillside detail, I also have the obligation to either attach garages to the neighbor’s garage or keep a one-meter distance. Then planting trees in front of the property is mandatory, among them lime and oak. Exactly which, I couldn’t remember. But that plays a very big role in what rooms I plan there in the south, which will eventually be connected. Furthermore, a fence to the street or a hedge is forbidden. So, it is not about placing a certain rectangle fixed in size well. You plan that flexibly _with_ the property and with the floor plan.

Plan space for a tree with a crown.

As I already said: in the south in front of the property.

the most sensible orientation of the house

would be, first to gather all parameters—not necessarily for us, but for you. One might think you haven't yet dealt with the property and the development plan, but only looked through catalog floor plans. That is too little if you want and have to spend half a million.

t). And the orientation naturally also influences a future photovoltaic system. …

Yes, then you already know in which direction the ridge must face. That’s at least a start. Then you look at the slope: how and where can something be?! Because fill or excavation towards the neighbor is not allowed.

What else must be considered at 8% for house placement?

80 cm over ten meters. You really have to watch where the rainwater flows because you probably have to collect it on your own property. So: sketch out the rooms where they could be. Sketch an access road or garage with one meter distance from the neighbors and try to get light from the south and quiet from the north. You can occupy yourself with that for a month with colored pencils. Then you can discuss mistakes, advantages, and disadvantages. That is the answer to the request:

your experience on how best to place a house … on a … property

Of course, we have been dealing with the floor plan and development plan ourselves for quite a while, which is why we are now at a standstill because we don’t know how best to position the house on the plot due to the "slope." I’m not worried about the tree in the south. If it gets in the way, it simply won’t develop a large crown; there are plenty of ways to manipulate it.
As shown in the picture, we had already considered the orientation. There is a carport in front. Next to it on the left is the storage. The idea is to get into the house with dry feet through the carport and under the roof overhang of the storage. The floor plan would be quite simple for that; I’ll attach it, but primarily I am interested in the "big picture" with the orientation.

It would help to answer all questions. With your house, the minimum 1.3/1 is not met based on your information. So 11*8.4m can work.

Yes, you are absolutely right that we are just under 1.3. Respect that you saw that so quickly!!! But that’s exactly what I mean, that it’s not about checking the floor plan of the house to the millimeter, but first about how to place the house and then work on the exact details inside the house… that’s the easiest way to first create a basis for how it is oriented and then think about the “smaller details,” right? For us, it’s only important to create as much space as possible in the living/dining area and to get two somewhat equally sized children's rooms.

there are plenty of ways to manipulate it.

The development plan states that you are there for the care. Well, that's already a good start if you are already thinking about euthanasia for important trees.

I have rotated the house along the contour line. The result is optimal photovoltaic yield and a large garden in the south.



I have determined the slope in the Bavaria atlas.



2.5m / 31.71m = 0.0788, so I already made a pretty good estimate.
