Chimney draft integrated in the stairwell

Hello everyone,

I came across the house building forum today. Since we will be starting the construction of our semi-detached house this year, I have quite a few questions that I will either research or ask here.

First of all, it is about the position of the chimney flue. Here is the planning from our architect:


Basically, we have no objections to this. However, from a terraced house that my parents-in-law once lived in, we are now familiar with this variant:


Here, the chimney flues are located in the corners of the concrete staircase, so that the adjacent rooms are free from "disturbing" boxes, which I find quite elegant.

Now my questions: Does the lower variant have advantages/disadvantages that I should consider? Is it a reasonable option according to today's standards (the terraced house is approximately 30 years old)?

Best regards,
Jupp

Did I phrase my concern incorrectly or post it in the wrong subforum? Or why haven't I received any feedback yet? I am grateful for any tip!

I rather suspect because it is very unusual.. I have never seen such a staircase shape, I think it takes up a lot of space.

The lower option is definitely much more expensive. How about discussing it with your architect?

If you absolutely want to have a piece of the 80s in the house, you will surely find a Kim Wilde poster somewhere :-)

The desired fireplace system would be labor-intensive to produce - built with cut small-format stones, nothing can be done as a prefabricated part.

In the stairwell, I would paint the 45° corners in turquoise.
