Attic expansion with dormer - experiences

Dear experts,

we are planning to convert our attic and expand it by two rooms + wet room. There is already a concrete staircase leading upstairs, which was originally planned during the house construction.

In the meantime, the architect has also made a draft and I would like to ask for your opinion and possibly ideas. Do you have suggestions or ideas on how to use the space even better or differently?

Thanks in advance,
Robert

This is what the roof looks like so far:



And here is a first draft:

We don't really need storage space up there - that's not what matters. The basement is big enough.

Measured against the total costs, it would hardly make a difference to make the bathroom half a meter wider. Then one would have many more options to design the bathroom more beautifully/more practically.

In general, I think it's ok. However, I prefer larger showers, so I played around a bit.

Option 1
I would take the risk and not place the bathroom dormer exactly in the middle... at least consider what else can be done there. The entrance to the storage area on the left side of the plan would then be from the bathroom.

Option 2 .. if the water pipes can also be located on the left side of the plan, you could basically mirror the bathroom, completely omit access to the storage area, and then only move the left wall in the shower area to the left. That way the dormer visually stays in the middle.
