Why is the design as it is? For example:

The first draft from the planner included a winding staircase, but since we don’t like those and wanted uniform step depths, the final design features a straight staircase. We also tried a staircase with a landing, but it took up too much space.
The design was therefore partly based on our wishes and partly self-planned. We tried to fit everything as well as possible.

Regarding the design, there is a storage room on the upper floor which will still be modified. Instead of a storage room, this will become the entrance to the bedroom. The wall where the wardrobes will be placed will be extended forward so it almost aligns with the fireplace. The bed will be positioned facing the window.
The bathroom layout is provisional and will be changed. A major wish is to include a small sauna, but this is a low priority.

I hope I have provided enough information and will try to respond as quickly as possible.
Thank you in advance for your input.
