Hello everyone,

Warning: "repost" after optimization. Reloaded.
https://www.hausbau-forum.de/threads/Herausforderung-Grundriss-für-unschoene-grundstueckform-Hilfe.32565/
What has happened so far:

I am currently planning a house on a somewhat challenging plot shape. (Of course, the question immediately arises, "why don’t you buy a plot with a better shape to work with?" Answer: in our region of BW Region X, there are hardly any affordable plots. The city’s land prices are around 480 €/m2 (about $45 per sq ft).) The plot is located slightly outside the city and was purchased relatively cheaply.

Okay, so I now have the plot, and “only” the house is missing on it.

Plot site plan with curves, measurement lines and boundary markers.

In advance: the building authority gives me no exemptions whatsoever.

A major challenge is the house geometry because I prefer having the terrace on the south/west side and still enough space inside the house.

In the first attempt, I planned several corners. House geometry as ground floor:

Based on your contributions and ideas, I completely rounded it into a quarter circle, which I also like better and can get used to.
Yes, the topic of walls, windows, and furniture is a bit more complex, but it has its charm.

Site plan: blue building footprint on plot with measurement lines in meters and curved boundary.

Currently, I have considered the following layout.

Here are the basic key data:

Development plan / restrictions
Plot size: 434 m2 (4670 sq ft)
Slope: no (or minimal)
Floor area ratio (FAR): 0.4
Building coverage ratio (BCR): 0.4
Building envelope: see development plan above (2.5 m (8 ft) to neighbors)
Edge development: no
Number of parking spaces: garage + 2 parking spots
Number of floors: 2 full floors (basement + ground floor + first floor)
Roof type: pitched shed roof
Architectural style: semi-detached house
Orientation: see development plan above, right side
Maximum heights/limits: ridge height 8.5 m (28 ft), eaves height 5.5 m (18 ft)
Additional regulations:

Client requirements
Style: modern
Building type: semi-detached house, 2 stories each approx. 120 m2 (1300 sq ft)
Basement, floors: 0, 1.5
Number of occupants, age: 2 adults, currently no children
Space requirement per floor: approx. 120 m² (1300 sq ft)
Office: family use or home office? Office in living room or children’s room
Overnight guests per year: 15
Open or closed architecture: mixed
Conservative or modern construction: modern
Open kitchen, kitchen island: open kitchen with dining and living area with access to terrace
Fireplace: optional
Music / stereo wall: TV on wall
Balcony, roof terrace: no
Garage, carport: garage yes
Kitchen garden, greenhouse: no
Other wishes / special features / daily routine, also reasons why or why not

House design
Designed by: myself
I like the larger terrace in the south/west directly from the living-dining area
Both bedrooms have their own bathroom
Bathrooms all aligned for plumbing

Cost estimate according to architect/planner:
Personal price limit for house, including equipment: 550,000 euros (without furniture or land)
Preferred heating technology: gas burner

If you had to give up, which details/upgrades
- Could you give up: not sure
- Can you not give up:

Why is the design the way it is now? For example:
I wanted, as described above, a large combined kitchen, dining, and living area with direct access to the main terrace.
For that, keep the house maximum to the north side. Two bedrooms, each with its own bathroom.

Here are my questions and requests for advice:

What is the most important / fundamental question about the floor plan in 130 characters?
1. Do you prefer the rounded design over the corners from the first draft?
Before:

Detailed 3D floor plan of a house with furniture, stairs and rooms

Now:

2D floor plan of a house with living room, kitchen and stairs, including measurements.


2. What do you think of my new floor plan?
Architect criticizes:
--Bathroom without windows (No-go?)
--Small entrance area, staircase without a landing is bad, basement stairs are bad
--Bedroom 2 should be in the east (if child)

3. How would you optimize the weaknesses from point 2?

4. How do you find the architect’s initial draft?

Floor plan of a building with red exterior walls; kitchen, dining area, living room, bathroom, stairwell.


Thank you very much in advance and best regards

Thanks a lot, Katja, that also looks good.
I’ll show this to my architect. I really like the living, dining, and kitchen area opening to the terrace in this design.

My architect has also presented a new draft, I’ll share it with you soon, but it follows the old layout pattern ;D

Best regards and many thanks for your support. I’ll update later about how the architect handles the integration.

I’m afraid I can’t get enthusiastic about this. What’s the purpose of the windows facing the garage? Or is it meant to be a carport? Why is the entrance on the west side? The toilet in the main bathroom is incredibly noisy in the children’s room. It’s also very important to know how much of the plot is still available. The south side, including the terrace, must be fully shown for a design discussion. Also, all parking options should be included. Or is it now just going to be a bungalow with a basement for a single family?

I’m still favoring option #12 if you are building the house for yourselves and it’s not fixed who else might live there.
If it must absolutely be a two-family house, you need to show the parking spaces first! Where else are all these vehicles supposed to be parked?
For that, I would move away from the focus on the south and consider a west-facing terrace instead. It would look something like this (upper floor identical):

Draw the actual furniture accurately in the open space as you plan to buy or already have it. The small dining table gives the impression of more space than there really is.

Where will the parking spaces be located?

Does the master bathroom have no toilet?

Somehow, the design feels like a random mix. An outdated master bathroom combined with the curve, which does not come across as a highlight inside.
Construction costs are extremely high, yet the living experience feels like a boring apartment.

If you like the curve and want it, then design your house so that its interior truly reflects that feature. Plan a house for 1–2 children or 3, depending on what you envision. If there are no children, you will have a spacious home for two.
A master bedroom with an en-suite bathroom featuring a freestanding bathtub.
A living room that incorporates the curve inside.
Recently, someone posted an amazing bathroom with a large glass area in front of the bathtub and a gallery. There are so many possibilities. Take a look, for example, at home design magazines or visit nearby prefab home show parks like those from Huf and similar companies.
You are investing well over $500K, more like $700K to $800K, so this should be clearly reflected in the interior.

There is an "s" missing. I also think it’s pretty cool to look at a Lamborghini while showering—though not from the side. And I have to agree with @haydee: if you’re already spending a fortune on the curved design, it should be prominently integrated. In theory, the quarter circle would be perfect for a split-level kitchen-living area with a seating gallery, if it weren’t for the detail that this feature on the north side would not be very energy efficient considering the two-story glazing involved.

I’m curious about the height planning. An eaves height of 5.50m (18 feet) isn’t very much. Depending on the ceiling height, a small roof slope on the upper floor is definitely necessary.
