Are the walls or studs outside load-bearing?

[Hulleman]

Hello,

We have been considering replacing the walls with the thicker sliding door model, but before we proceed with the planning work, I want to know what is load-bearing or not.
Can anyone discern anything from the pictures?

Edit: Ideally, we would like to have an "open" corner.

Just guessing, but it's probably load-bearing.
There's probably some kind of beam as it looks now.
However, it's not enough if you're going to open up everything.
Additionally, it's not entirely impossible that the windows themselves are load-bearing and support a small beam.
I've been to more than one house that has this.
Especially in the late 60s and early 70s, I've come across this.
Someone needs to take a proper look before you proceed.

Thank you for the response.
What type of expert/professional should one contact about this?
Construction engineer?
