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.

Site plan with yellow and pink zones, blue outline, north arrow, max single-family home 209.50 m

Site plan showing a plot with lawn and curved driveway

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

You don’t have to focus on "your square meters": square meters is a measure of area, not quality. Plan your house while considering the building envelope as the boundary framework. What you should avoid—and what can only go wrong—is trying to fill the building envelope completely and, in my opinion, hoping without reason that the house placed within it will automatically have valuable living space.

...a good solution might be the L shape or option 1 maybe, or=?

Or maybe something like this:


Floor plan of a house with terrace, living room, kitchen, hallway, bathroom, toilet, and storage room.



Floor plan of a residential house with bedroom, master bathroom, child’s room 1, child’s room 2, kitchen, and storage room.

I will look into the options in the next few days and report back on what I decided.

Try to at least think about your space and room requirements. Start with a list of rooms you absolutely need (excluding those you might want in 20 years). Add the sizes you imagine for each room so that the total area comes to a certain size (initially, a maximum of about 140 m² (1506 sq ft) is sufficient). Then, arrange these rooms as simple rectangles within the building footprint. As gaps appear, a guest toilet, a cloakroom niche, and a hallway will form somewhere.

It might sound childish, but give it a try.

Thanks a lot



So, the curve is out. Option 2 is definitely the easiest, but then I don’t reach my m². A good solution would be the L-shape or maybe option 1, right?

Regards
Many thanks


You know:
It would be really helpful if you learned from the previous posts and oriented the drawings with a north arrow. Other threads are being answered simultaneously here and time is taken, so the orientation information gets lost quite quickly. For newcomers, north is always at the top!

It would also be great to see the entire property, not just cut off at the building boundary. The relation to the neighboring lots is completely missing here as well.

Add the size of each room as you imagine it, so that the total area comes to a set amount (initially, a maximum of 140 sqm (1506 sq ft) is sufficient). You then arrange these rooms as simple rectangles within your building plot, moving them around until leftover spaces form a guest toilet, a cloakroom niche, and a hallway.
It sounds simple, but give it a try.

No, that sounds smart and effective—you’re just “giving up” the high-tech 3D planning gamer experience. The real question is why someone wants to “reach their target square meter size” at all, if apart from a vague chance of their parents moving in (is there even a suitable partner with in-laws involved yet?), there is no qualified need they are trying to fulfill.

A joyful little experimental project full of challenges. Who moves in later seems completely unimportant. The space should be used optimally at any cost. Residents will surely be found once the rooms are available – if necessary, the parents – whether they want to or not!

Maybe someone is lonely? ops:
