Ideas for attic floor plan - one room too few

Good day,

I have attached the floor plan (attic) of a house, the renovation of which I am currently planning.
Currently without an architect or similar.

So far, I do not have a good idea of how the floor plan should be designed in the future.
The following points are problematic or need to be considered:

- The bathroom should remain on the side where it is currently located.
- The bathroom should be somewhat enlarged (due to the roof slope (45 degrees), the bathroom is very small)
- The washing machine should fit in the bathroom
- A dressing room should be created next to the bathroom.
- There should be two bedrooms
- Skylights should be installed for the bedrooms (south side: on the left in the plan)
- Somewhere a desk should find a place.

I would appreciate one or the other creative idea. :)
Best regards

Well, a more readable plan would be helpful, in which the window sections/walls are individually dimensioned. Or can windows simply be closed and repositioned? Then information about the knee wall height or markings showing where the 1- and 2-meter lines are. Furthermore, information about the type of bedrooms is missing .. 2x double beds, 2x single beds, etc. Closet .. what amount of storage space? Desk .. just in one of the bedrooms or how?
