Hello dear community,

we are planning to build a single-family house and have already thought further ahead. We would like to be able to divide our house into two separate living units if needed. This way, an older child could move into the apartment above while we continue living on the ground floor, or we could rent out the upper unit if necessary. The ground floor should be accessible without barriers, with a shower in the bathroom. I would really appreciate your opinions on the floor plan I have drawn and any suggestions for improvement. Here is the floor plan:
Floor plan of a house with five rooms (9.34; 8.79; 13.12; 13.28; 26.12 m² (100; 95; 141; 143; 281 sq ft)), doors and furniture.

Utility garden, greenhouse No</TD>
Additional wishes / special features / daily routine - Ground floor and upper floor should be usable as separate living units, but not immediately—this option should exist; both floors should be acoustically separated. An open kitchen is preferred for visual spaciousness. The ground floor should be convertible to barrier-free, including a larger shower, wheelchair-accessible sink, wider doors. Fireplace desired, ideally usable from both ground and upper floors. Both floors should have a built-in window seat exactly where indicated on the plan for an unobstructed garden view (although it is the neighbor’s garden, having a nice view option is appreciated). Currently, the upper floor has 3 bedrooms, but the white wall should be removable to make the layout nearly identical to the ground floor if needed.</TD>
House Design
Who created the design: DIY: self-designed</TD>
What do you especially like? Why? The open and spacious living room with open kitchen</TD>
What do you dislike? Why? Ideally, the kitchen should be separable by sliding doors; double sliding doors would be great but aren’t included in the current plan. I am bothered that the hallway on the ground floor is poorly utilized and wastes space.</TD>
Cost estimate according to architect/planner: Not yet available</TD>
Personal budget limit for the house including fittings: 550,000</TD>
Preferred heating technology: Preferred: air source heat pump + photovoltaic system + decentralized ventilation in the living room and one bedroom on upper floor</TD>
If you have to give up, which details / extensions
- could you give up: Size of the ground floor bedroom; double bed still required for two people if the children move out. A closet in this room is not necessary, although it might look odd if there is only a bed.</TD>
- can’t give up: The window seat is very important to me.</TD>
Why does the design look like it does? For example I looked at several accessory apartments and combined their features somewhat. The key difference is that the plot itself is small and I want to preserve as much garden as possible with a hybrid solution usable for us now and optionally as a separate apartment later. Due to limited remaining garden space, I want a roof terrace, since I feel enclosed by neighbors to the south and west and this helps to access sunlight even in seasons with low sun angles.</TD>
What makes it, in your opinion, particularly good or bad? The house should adapt well to many life changes (2 children and living in it into old age, then renting out the upper floor or using it for a caregiver). Daily routine: wife comes home around 2 PM, I come home around 6 PM on weekdays. I work a lot from home on weekdays. We enjoy having guests on weekends and want the option for overnight stays as some relatives come from other regions.</TD>

Here is the site plan. The house I am planning to build is the one in the top right corner.
Site plan: two buildings; a large square on the left, a building with interior rooms on the right; north arrow.

Site plan without reference to the street?

Is there no zoning plan? With a granny flat, definitely 2 parking spaces.
