Then sketch how the neighboring house is positioned.

And garage in the basement = cellar? Is there also a slope? Then roughly mark the elevation points within the triangle.

And don’t make me pull everything out of you one detail at a time.

The neighboring buildings shown in the picture are numbers 222 and 224. The neighbor has allowed themselves a spacious courtyard.

Yes, we want the garage underground so that the basement apartment can have windows on the street side. This is achieved by designing the driveway to allow daylight access. There will also be a front door to the apartment directly in front of the garage door.

There is a slight slope. Elevation points are approximately: 252.56 meters (826.7 feet) on the left, 252.31 meters (826.0 feet) at the top, and 251.35 meters (824.9 feet) at the bottom.

I have no intention of withholding any information from you. I’m happy to provide everything upon request.

I assume we will need to plan an L-shaped building. Flat roof, many windows, especially downstairs, because the orientation and the tree reduce the amount of natural light. We want a simple design, nothing extravagant.

I’ve never built anything before, so I’m a complete beginner. I hope for some beginner’s protection.

Why have a granny flat?

I would plan a rectangle, positioned as far east as possible.
With an L-shape, you lose the southern sunlight.

Difficult: small plot, large house, triangular shape, and a huge tree.

Two stories plus a basement. We are planning a granny flat in the basement. Living area is around 200 square meters (2,150 square feet), maybe a bit more.
Garage in the basement on the right side next to the neighbor.

This is a simple house without any extras:

But that’s not what you mean, right?

In my opinion, the question of placement doesn’t really arise. I haven’t seen anything about an allowed edge construction or similar. That means a 3-meter (10-foot) setback from all boundaries. With some luck, it might be only 2 meters (6.5 feet) from public walkways or so. But I wouldn’t assume that at first, and whether that would even look good is also questionable.

You can’t even fit a 10 by 10-meter (33 by 33-foot) house into the building plot. Or have I fundamentally misunderstood something? Here, you will probably have to build at an angle just to reach the required square meters. What are the floor area ratio and the plot ratio? I think the tree is your smallest problem.

This is going to be interesting. 200 m² (2,150 sq ft)? Only if you were allowed to build three stories, maybe.

No. Exactly

I believe that is the biggest problem. A 7m (23 ft) oak tree will almost certainly be protected under the local tree preservation regulations, and generally the entire drip line area of the canopy is off-limits for construction or sealing. So first, clarify with the local authorities how much area is actually available for building, then you can focus on the details.
