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

According to the photos, the oak is located almost exactly in the middle of the northern boundary. The first photo seems to be taken favorably in winter, but photo 2 shows the three main trunks very clearly. Additionally, with 2 aerial photos in the Esri Aerial data (bottom left), it looks really bad, the oak must be huge.

A great tree... the city should have kept the property itself, a sandbox on the premises, benches under the tree and you already have a great recreational spot... but then to put a house on it.... silly. Especially with a basement - then you might as well cut down the tree - everything is rooted underneath...

Under the given conditions, the plot is not buildable

And again I disagree. Your plan is too inaccurate. The northern boundary runs too far north and the scale is also too inaccurate. Let's wait for a plan from the OP.

... the city should have kept the plot itself

... and what if it wasn’t even owned by the city?

.... silly

I think some facts are still missing for the use of this term here.

Even with a basement - then you might as well cut down the tree - everything is rooted underneath...

That’s what the tree protection ordinance is for. Well, it’s your area of expertise, but to my knowledge, keeping the crown drip line area free has proven effective. If you have other findings, I would be very interested.

That looks nice. Maybe one could build a treehouse? *SCNR* Aachen would be too far for me, but a garden plot could definitely tempt me

And again I disagree. Your plan is too inaccurate. The northern boundary runs too far north and the scale is also too inaccurate. Let's wait for a plan from the OP.

Yes, even if the drawing is inaccurate (it is not, but whatever), at best there will be half a meter more space somewhere and the house may then be 3.70 instead of 3.20 meters wide.

This is not about the precise measurement of the string framework, but about virtually pacing out a building plot.

Even a highly praised architect cannot remove the tree.

ist sie nicht

Believe me, it is inaccurate.

aber egal

Not indifferent, because it’s not about 50cm but about 2m.

... is pegged out to 2mm. So it’s about a factor of 10³, which definitely plays a role in assessing buildability. The plot is suboptimal for building, no question. Exactly for that reason the original poster is asking here for ideas.

Auch ein hochgelobter Architekt kann den Baum nicht wegfällen.

Maybe he finds a loophole in the statutes?
