House entrance with curved roof

because it fits well here
A rather original entrance from friends

Hello,

At the moment, my considerations are heading towards a steel substructure split in the middle - which would still be transportable in terms of size and can be galvanized in a company.
This frame consists of 42mm pipe. That - according to my friend, the smith - he can produce without a bending machine.
On this pipe construction, wooden slats are attached with pop rivets, which form a surface upwards as smooth as possible without steps. This surface can be covered with sheet metal using normal roofer techniques.

I have had to design strange things in steel before, but riveting wood to a round pipe? That really stretches my imagination.

Alternative proposal:
As a horizontal substructure, a large wooden board (pine from the sea, OSB, ...) on which insulation (e.g. 100mm base thickness) and further insulation like mineral wool shape the peak and a PE waterproofing membrane is welded on.

so different are the assessments ...
Wood to round tube:
Wood and tube get a hole in the right place and - voilà - there sits a pop rivet. Although that would not be my favorite connection, it is relatively easy to build and would also hold - at least that is my conviction. Each wooden board of course gets 2! rivet points, which would be located on 2 tubes.

The tip of my canopy idea belongs to the most important parts of this construction. How it is supposed to be "modeled from mineral wool" "blows my mind"

What I particularly like about the plan – and why I would like to build it without a substructure – is that a material just a few millimeters thin, installed in this shape, if fixed to the wall and supported from below, would be completely stable in itself.
So to speak, a minimum amount of material is needed to have the necessary stiffness against the wind – and a favorable shape for water runoff.

I am holding back here "aus Keineahnung" and would therefore normally remain accordingly invisible, but I still want to point out that this is a thread I like to follow.

The stupid catch is: One direction of the sheet metal remains perfectly straight, but both sides, right and left, have different radii ... and of course, they have to fit "exactly". The cardboard model is extremely easy to make: 2 identical pieces are cut out (unfortunately, I don't have a drawing of the cut available at the moment) and are glued together on one side (with adhesive tape). Everything that forms in shape emerges automatically from this. But unfortunately, cardboard doesn't last long in the rain :-((
