ᐅ Looking for ideas for a square floor plan for a duplex or semi-detached house.

Sturkopf86Hello everyone, we are looking for a floor plan for a semi-detached house!
Most semi-detached houses are long and narrow, but our building area does not allow that.
We want to live in one half of the semi-detached house
And rent out the other half. We prefer not to be alone.
Development plan / restrictions
There is only one supplementary ordinance. Construction according to Paragraph 34.
Size of the plot: 815 sqm (8770 sq ft)
Open construction method according to Paragraph 34.
Slope: yes, over 16 m (52 ft) there is a 1.5 - 2 m (5 - 6.5 ft) gradient.
Floor area ratio: 0.4
Floor space index: not specified anywhere.
Building area, building line, and boundary
8.5 m x 16 m (28 ft x 52 ft) according to surveyor.
Edge development: no
Number of parking spaces: flexible
Number of floors: 1.5 - 2 (neighbors)
Roof shape: gable roof > 35 degrees
Architectural style: classic mixed with modern
Orientation: see drawing
Maximum heights / limits: unknown
Other requirements
Homeowners’ requirements:
Style, roof shape, building type
Classic-modern, gable roof, semi-detached house
Basement: yes, floors 1.5 - 2
Number of people: 3 adults, 2 children, 1 toddler
Room requirements on ground floor: kitchen, living room, dining room, shower bathroom
Upper floor: master bedroom, two children’s rooms, bathroom.
Office: nice to have, but not mandatory – home office!
Guests sleeping overnight per year: none
Open or closed architecture: open
Conservative or modern construction: flexible
Open kitchen, cooking island: would be great
Number of dining seats: 8
Fireplace: no
Music/stereo wall: no
Balcony, roof terrace: no
Garage, carport: yes, 2 spaces
Utility garden, greenhouse
Other: 1 garden north, 2 gardens south
Requests / special features / daily routine, also reasons why this or that should or should not be included: we are open to everything, we want to build something that makes sense! It does not need to be large! We currently live in 102 sqm (1100 sq ft) plus basement and that is sufficient.
House design
Who is responsible for the planning:
We do not have one yet! The plan below would be acceptable for us, but it needs to be made quite square. Has anyone worked on a similar project?
- Architect: We want an architect to help us but do not want to hire one unprepared.
- DIY: That’s why we want to gather as much input as possible.
What do you particularly like? To make full use of the building area, if possible. Why? So that there is not a 100-130 sqm (1075-1400 sq ft) house on an 815 sqm (8770 sq ft) plot, and we would like to have neighbors!
What do you not like? The 8.5 m (28 ft) width of the building area. Why? 10 m (33 ft) would be optimal for a nice semi-detached house.
Price estimate according to architect/planner:
700,000 euros without land!
Personal price limit for the house including equipment: 400,000 euros per semi-detached half
Preferred heating system: solar thermal combined with gas
If you had to compromise on details/additions:
- What could you live without: office
- What can you not live without: large kitchen, all activity centers around the kitchen and dining room, we hardly ever use the living room!
Why is the current design the way it is?
We actually do not have one.
Standard design from planner? Yes
Which requests were implemented by the architect?
A mixture of many examples from different prefabricated house catalogs.
What do you think makes it particularly good or bad?
No compromise on the kitchen, as it is our central living space.
Bad: possibly planning a semi-detached house, maybe better a house with a granny flat?
What is the most important/basic question about the floor plan summarized in 130 characters?
How can we combine family life with spatial design in one half of a semi-detached house?

Alright, here are the questions related to this post as well. You should only respond here from now on.
Hmm... Has the plot been oriented north? -- Done - YES
Is the dashed line the building envelope?
How are the roads and driveways arranged?
How are the neighboring plots situated?
-----------------------------------------------------------------
It would be useful if the floor plans shared were aligned to their actual location on the plot.
Why do you consider the posted semi-detached house floor plan useful? You actually have the option to build much wider. Take a look at the room sections (barely 250 cm (98 inches) wide), the parents’ areas and the walk-in closets drawn there... well, wardrobe spaces with little storage and limited room to move around.
The room doesn’t support that, even if you swapped living and cooking areas.

large kitchen, for us everything happens in the kitchen and dining area, we rarely use the living room!

Well, Google is your friend. You can find plenty of suggestions there. Here’s a reminder that as the builder, you naturally have the option to claim a larger portion of the property for yourself— for example, 9 meters (30 feet) in width— and only allocate 7 meters (23 feet) to the rental unit.
If the land isn’t, like with MadameP
(https://www.hausbau-forum.de/threads/grundrissplanung-Doppelhaus-17x10m.28411/),
extremely expensive and renting out is intended to cover half of the land costs, I wouldn’t even consider building a semi-detached house. Especially not with a maximum building depth of 8.5 meters (28 feet).

Hello, thanks
Yes, the thin dashed line -- -- -- --
is the building envelope! The thick dashed line on the right and top at the property boundary is intended to be a wild hedge, which we will have to plant after construction! There is only a buildable plot on the left (not yet developed!). To the right and above is a water protection zone II and building is not allowed there. So we basically have only one neighbor on the left.
The driveway—good question! Am I allowed to place it wherever I want? Left or right?
I couldn’t find any regulation about that anywhere!
On Google, there are many duplex floor plans, but I haven’t found one with a square footprint! Maybe it’s because nobody wants to build that way?
MadameP, I have read all your posts and I am following closely!
Nothing is set in stone, this is just an idea. We don’t need a huge house. A small single-family home on 815 m² (≈9,000 sq ft) of land might look a bit lost?!
What would you build? We are open to all suggestions...

What would you farmers do? We are open to any suggestions.....
I don’t think so either! If I had the choice, I would also build a single-family home. You can do whatever you want on your own land. With neighbors, especially if they are as close as in a semi-detached development, you always have to come to an agreement...
In the end, we decided to sell. Renting it out wouldn’t have made any tax sense at all; on the contrary, we would have lost money due to the taxation of rental income. Now we are selling and hoping for a small profit. But you guys got that, right?
