Thank you for all suggestions!
------------------
Development Plan/Restrictions
Building gap in an older residential area, no detailed development plan, but subject to §34
Plot is surrounded by roads on three sides
Plot size = 610 m² (6566 sq ft)
Slope = approx. 0.50 m (1.6 ft) south-facing slope
Site coverage ratio = not explicitly defined
Floor area ratio = not explicitly defined
Building envelope, building line, and limits = not explicitly defined (state building code requires 2.50 m (8.2 ft) distance)
Edge development = a neighbor’s shed at the northeast boundary
Number of parking spaces = 4 (state building code requires: 2 per dwelling unit)
Number of floors = 1 ½ (presumably required due to §34)
Roof type = gable roof (presumably required due to §34)
Architectural style = similar to surrounding buildings (§34)
Orientation = unclear, existing buildings are varied
Maximum height/limits = unclear, existing buildings mostly around 7.50 m (24.6 ft) ridge height
Other requirements = none known
Immediate surroundings have no trees
Owners’ Requirements
Architectural style, roof type, building type = no preference, just what’s allowed
Basement, floors = no basement (budget reasons), desired number of floors is 2, but only 1 ½ permitted
Number of residents, age = initially Dwelling Unit 1 (ground floor): 2 adults (tenants or holiday renters) + Dwelling Unit 2 (attic): 2 adults, 1 child (2 years old)
In about 10 years, after conversion to a single-family house: 2 adults
Space requirement on ground and upper floor = small, current space needs not permanent, DU2 (attic) needs about 10 m² (108 sq ft) of storage space in basement/attic
Office: family use or home office? = no dedicated office but a utility/cleaning/common room
Overnight guests per year = none
Open or closed architecture = open
Conservative or modern construction style = no preference, just what is permitted
Open kitchen, cooking island = open kitchen yes, cooking island only if space allows (therefore no)
Number of dining seats = initially DU1 (ground floor): 4 + DU2 (attic): 4
Fireplace = no
Music/sound system wall = no
Balcony, roof terrace = no (budget reasons)
Garage, carport = no (budget reasons)
Utility garden, greenhouse = no
Additional wishes/special requirements/daily routine, also reasons why certain things should or should not be included
= Single-family house divided into two small rental units for a few years, one rented to relatives,
- to avoid a separate utility room on the ground floor, building services/heating/ventilation systems will be distributed between the common room and the attic,
- the seemingly “normal” dormer on the south side is omitted mainly due to budget,
- the roof pitch is steep (45°) to maximize usable space,
- the house orientation should allow wide unobstructed views and solar panels should be feasible,
- the site is very sunny, so excessive south-facing windows are not desired
House Design
Planning source = do-it-yourself
What do you particularly like? Why? = House can be easily converted into a single-family home
What do you dislike? Why? = Ground floor space utilization is not optimal, no practical option to add a balcony later on the attic floor
Cost estimate according to architect/planner = unknown (“can be done very nicely for 400000”)
Personal budget limit for house including equipment = 200000 (two hundred thousand), excluding kitchen and furniture
Preferred heating system = district heating (required by the municipality, but acceptable)
If you have to give up something, which details/extensions
- can you give up = everything “common today but not 20 years ago,” kitchens, glass panels in front doors, separate dressing rooms, roller shutters on north/west/east, roof windows
- reluctant to give up = underfloor heating (because it is hard to retrofit)
- cannot give up = utility/cleaning/common room, some storage space somewhere, division into two rentable units
Why did the design turn out as it is now? = A mix of many examples from various magazines/internet, simplified/reduced to fit the very limited budget

By the way, the light blue shaded rectangles on the site plan are intended to represent parking spaces for cars
Hm, how do you envision the staircase? It’s open and floating in the common area, is that intentional? The staircase needs to be enclosed from the common area side; a wall must separate the staircase shaft from the common room along the side above the stair slope, leaving some space for the handrail. The staircase belongs to the attic apartment.
For a holiday apartment, many things might be acceptable, but for a family of three, I find the upper floor unlivable. I don’t see any way to run a household. Washing machine? Space for a broom and other cleaning tools? And this would also have to be provided for the holiday apartment. I will take a closer look at that. At least for the attic, the washing machine fits on the right behind the door between the wall and the bathtub.
Why don’t you just go for a standard house where you can section off the stairs leading to the second unit right at the entrance and then lock off a room that would be accessible from the outside. That is indeed another option I am exploring. However, one-and-a-half-story prefab houses are almost never suitable for horizontal division because it’s difficult to fit a bathroom downstairs and a kitchen upstairs. Prefab bungalows rarely allow vertical subdivision either, as they are optimized for their intended use. And multigenerational bungalows are above the budget.

This is not worth discussing. I also think it’s a pity that I am not an architect. What is considered a good design in this situation? I have looked at many floor plans here in the forum, but with similar conditions, it seemed that the discussion always ended up with building the house solely as a single-family home, without subdividing it before (or after) its use as a single-family dwelling. However, I see with acquaintances and friends that old houses are divided into several apartments, or old houses with many tiny units are converted into a single-family home. It seems rare that this is planned like that from the start in new construction.
Why don’t you build a house the way you want it to be in 10 years and rent it out for now?
The children’s room can later be used as a guest room or home office.
The total floor area is slightly smaller, but there are no two bathrooms, no two kitchens, and no costly renovations later on.

What would be a good design in this situation? That might be easier to answer if you also described the desired final condition here. Besides, the situation is quite unusual, so it will be difficult to find comparable examples, and certainly no standard solution.

Why, too interesting? No, you could go on forever listing the dealbreakers. Some prefabricated house manufacturers do offer homes designed for two households. These are often marketed under names like multi-generation house or family home, etc. You can definitely find better options there, at least to get a first impression of this kind of solution.
