Floor plan tube house L-shape triangular plot including oak tree

Underground garage and granny flat are out of the question

You have to position the house as close as possible to the street. There is no space for a driveway.

You should still show a little more respect.

Hello? We can't help that you got taken for a ride. You won't build a house in this country as long as the tree stands. I'd bet my house on that. And taking the tree away, aside from the fact that you're not allowed to, you wouldn't be able to live there then because the neighbors would stone you.

We can’t help that you got taken advantage of.

What’s that supposed to mean? You don’t even know that.

I’d bet my house on it.

Bet accepted! Take his plan from #38, take his property from TIM-online, adjust the plan and you’ll see that there is about 4 meters of space (+/- 50cm) next to the tree, increasing towards the street. Garage within the building setback, far enough from the street so that a usable driveway including windows for the basement can be built. If he has enough money, he can build the foundation in the root area of the tree with micropiles and thus avoid at least the safety distance, which by the way is not even mentioned in the tree protection ordinance.

Stay cool

I am the coolest ever.

You didn’t make a mistake

Everyone makes mistakes. But what did you want to say with that? What glimmer of hope do you see if any statement by me is wrong? This thread is a good example of fake news: Yvonne asks in #53 if the property belongs to the municipality, Müllerin assumes this already in #70 and Yvonne then takes it as fact in #90. Funny!

What’s that supposed to mean? You don’t even know.

I think I do.

Bet accepted!

What do you offer?

Take his plan from #38, take his property from TIM-online, fit the plan in and you’ll see that there is about 4m space (+/- 50cm) next to the tree, ...

I’ve already tried that. We don’t know the exact dimensions anyway. But the aerial shot with Mottenhausen’s sketch is, in my opinion, more accurate than the OP’s drawing. It would then be a building with a maximum width of about 4m – rather less. Depending on how the tree is actually positioned now, the depth is also very limited. I’m not saying that you couldn’t build something there, for example a garage. But I don’t believe the OP will spend several hundred thousand euros on any kind of tower.

I know that.

Go to Google Maps, click on Satellite there.
Right-click on a starting point. Select "Measure distance" in the menu that opens. If you now click through the important measurements, you will notice that Mottenhausen is closer to the truth than the OP.

I always have to play around with such dimensions ... and I built the "underground garage", added the entrance to the granny flat, and then simply built a house with some slanted walls to show what I think is the maximum amount of space possible on the plot with the given data.

I don't see a granny flat as sensible there ... there is just enough space for 1 window.

The driveway will be steep and actually the straight area in front of the garage should be more than the approx. 2 m that I have drawn now.

Without interior walls, about 48 sqm of space per floor. That means ground floor, upper floor, and attic with a knee wall height of currently 160 cm and a roof pitch of 22° have been drawn.

It is not yet taken into account that with such a driveway the neighbor's plot must be supported, which also takes up space again.
