Multistory Treehouses

I remember treehouses from my youth, often put in between the branches and able to hold many children at once.

Such treehouses were put easily at a 2~3 floor height, with nothing below it.

Perhaps then, treehouses can be used to build quick, dense, 2~3-story housing (similar to how Brooklyn is) stably? The tree can hold on to the 3rd floor, and the building below it would not be load-bearing, allowing the usage of containers or other cheap materials, perhaps allowing the 2-floor building below to be made of weak parts.

A proposed example would be a 3rd-floor treehouse, a 1st-floor woodhouse with a flat top, and a 2nd-floor "house" made of lightweight tarps.

What are your thoughts? I haven't seen such attempts yet.

Either this, or vertical campsites with lightweight platforms, where each floor can have a tent set up. I am no civil engineer, however, so take my proposals as a half-joke.

Interesting idea.

Some things to compensate for

Tree changes size over time.

Tree moves differently in wind than most building materials.

I think that's why so many tree houses (like people live in) aren't connected to the ground much.  But I know more about trees than building, so there might be other considerations.
