Location kitchen and living room

That's why I didn't fill out the questionnaire. Most things are not under my control.

I almost have to take notes here to get all the information.
Especially with practice and private, but MRH and bicycle shed as well, it's necessary to write everything down in summary.
For example, could you possibly install a door instead of a patio door that can be used as a front door? Can you even get out of the garden? And so on...
I've skimmed through... can patients be expected to manage stairs? Does the practice need daylight or is insulated light/daylight lamps sufficient... etc.

Honestly, I would leave the floor plan exactly as planned by the developer.

I would also leave it like that.
Practice on the ground floor, front room. Kitchen in the middle. Good light there and a mobile workstation. Dining area and living room facing the garden.
Upstairs, one room as a living room, the rest divided into bedroom and dressing room.
If the row of terraced houses isn't too long, then around the house to the bicycle area... or yes: bicycle in the hallway. You don't necessarily need the door next to the stairs to the rear room anyway.

I'll try to summarize everything again: The mid-terrace house is primarily my residence. The practice is limited to one room, preferably with a window, which serves as a consultation room. It does not need to be very large; 3 people should be able to sit comfortably without practically sitting on each other's lap. This practice is not my main professional focus. Therefore, it can be suboptimally designed. Adequate is sufficient. It is only used for a few hours of work per week, maybe 2-5 hours. The waiting room is limited to a folding chair in the hallway that is placed there when needed and otherwise stored in the utility room. The practice does not need to be wheelchair accessible or age-appropriate. The terrace door, which is the closest door from the bicycle shed, is already installed and is a sliding door. I could probably change that, but it would cost a lot of money. The sliding door has a locking mechanism on the outside. The shed has an access path behind the garden. My house is the 3rd house in a row of 10. When I come home, I have to decide whether to enter through the front door or go to the garden (because of the bicycle). Then I just have to go "around the block" in one direction or the other to the garden access path and from there enter the garden and the house. Unfortunately, I don’t have a layout plan yet.

ah, we overlapped in our posts. If I leave the kitchen as it is, it would be good if I could extend the right-hand side row by about 40cm. I plan 3 tall cabinets (3x60), 1 cooktop (1x80), a base cabinet for dishes (1x60) and some additional storage space on the other side of the cooktop (preferably 1x40, but it can also be 1x20). That adds up to 3.60 or 3.40. Otherwise, the cooktop must shrink to 60cm. Then it would be 3.20. Hopefully, that would still work. I don't know yet how thick the walls are that "enclose" and delimit the kitchen row. I just noticed they look like load-bearing walls. That would be bad. Because then the kitchen shrinks to about 300.

Having the practice downstairs would be nice. But then the beautiful room is gone, used only a little. Do you have experience with the living room upstairs? I can't quite imagine it yet.

You really have a luxury problem

Having the practice downstairs would be nice. But then the beautiful room is gone, only used a little.

You can mix the living room or dining room with the practice. Patients like it when they sit personally, provided you don’t clutter yourself and keep everything somewhat minimalist. Patient leaves, and you play music. Computer and laptop disappear into a cabinet. You can also extend the kitchenette a bit and transition into a built-in cabinet...

I once had the living room upstairs, but it was no good because I often want to do things in the kitchen.
