ᐅ Single-Family Home – Design Planning – Request for Feedback

Hello,
I would like to start a new thread regarding the initial design planning.

Previous thread: Single-family house – Opinions on our design
https://www.hausbau-forum.de/threads/Einfamilienhaus-Meinungen-zu-unserem-Entwurf.25622/

Here are the main points:

The foundation slab is already in place: 12.49 x 12.49 m2 (41 x 41 ft2) and 30 cm (12 inches) thick.
The foundation slab was inspected for quality by an energy consultant and a structural engineer – no issues were found.
The locations of the underground drainage pipes are marked in the image titled "Foundation Slab - Drainage Pipes."

The house is planned to be built on the existing foundation slab. Demolition is not planned.

The house needs to be constructed as a one-story plus attic (E+1) with a gable roof at a 22° pitch.

The original submission plan from the previous owner was applied for but has not been received yet.
Our own submission plan from the architect exists but was mostly rated as unsatisfactory.

Negative points in the submission plan:
  • Ground floor + upper floor
    • Staircase between ground and upper floor is not properly dimensioned
  • Ground floor
    • Staircase unsuitable, takes up too much space; entrance to living area is through the kitchen
    • Access from garage to house does not fit due to height differences
  • Upper floor
    • Staircase unsuitable, room layout and a dark hallway with hallway width only 1.10 m (3.6 ft)
    • Balcony extends across the entire house length
      • See east elevation under the image “View all sides”
        • The balcony was extended because the upper floor protrudes 70 cm (28 inches) beyond the ground floor, covering the resulting overhang. In the previous plan, the balcony was only above the bay window.




Our specific requests:

We like the ground floor and its room layout quite well. However, the half-landing staircase should be replaced by a space-saving alternative.
The staircase was placed centrally to allow the desired rooms to be created.

  • Keep the technical room in the marked position for connection reasons, near the turning circle.
  • Keep the front door position as shown – access from the garage plus guests parking in front of the garage.
  • Central staircase to maintain short walking distances.
  • Type of staircase: corner staircase with quarter turns (1x or 2x 90° turns) or straight staircase. Spiral staircases are not desired.

  • Modern house with an open kitchen and living area.
  • Home office.
  • Guest toilet with shower.
  • Pantry for freezer, food, and beverages.
  • Large children's bedrooms, preferably on the south side.
  • Room for a walk-in dressing area.
  • Separate entrance to the master bedroom, not through the dressing room.
  • One master bathroom and one children’s bathroom.
  • Small utility room (approx. 6–8 m2 (65–86 ft2)) on the upper floor for washing machine and dryer.
  • Tiled stove; the chimney flue should not run through the children’s bedrooms. Preferred route is through the bathroom or utility room.

I expect/hope to get a proper house from the discussions and the resulting advice,

I didn’t mean the discussion with us. I meant what you expect from the discussion with the builder. As far as I know, they only have one type of discussion: the square or cubic meter costs X with us. If that doesn’t suit you, then choose cheaper tiles / simpler doors / fewer sockets, etc., or paint it yourself.

So again my question to the group: Would you like to help me [...] put together a decent floor plan using your experience?

That has already been confirmed several times, most recently in the form of a handful of alternative floor plan sketches by Yvonne. I’m not much of a draftsman and have to rely on you being able to imagine an L-shaped staircase just behind the front door yourself.

Hello, I’m getting back to the old topic after a longer business trip.
In the meantime, we have visited more show homes and have come to the conclusion that the staircase in the living/dining area would really bother us.
Therefore, I tried again in Homebyme to create a floor plan that fits the conditions regarding connections/sewer pipes in the basement. I think the layout is now more spacious compared to the original drawing (drawing with the half-landing staircase).

Before I hand over this version to the draftsperson, I would like to get your feedback one last time.

Thank you

Perhaps modern paintings are missing an instruction manual

I have been following from the beginning and am curious to see what the structural engineer will say about your floor plan and what figures will come out. I believe simply submitting a floor plan is not enough. They should at least take a look at the plot of land and the foundation slab and be allowed to give their opinion.

User manual

Hello 11ant, I will commission the user manual as soon as the layout is finalized. I can’t ask the draftsman to create a new drawing for every change.
This is about comparing the staircase in the living room with the staircase in the hallway and the rest of the layout.

@Zaba12 – as soon as the drawing is ready, I will start discussions with the technicians.
