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.

First of all: You are building BIG, and the costs have already been mentioned here several times!

Here is a proposal that reduces the hallway areas as much as possible—if you can even call it reducing in the case of a straight staircase.

Ground floor:
In one of the earlier designs, the kitchen was swapped with the office. Advantage: from the kitchen, you have a better view of the main entrance and possibly the children playing on the street.

The office is sized large enough to also accommodate overnight guests. Disadvantage: the access is through the living room. However, this could be changed, which would reduce the size of the entrance area.

The office and kitchen could also be swapped.

The hallway will have a bench next to the coat rack.

The kitchen gets a separate entrance.

Upper floor:
The hallway has been made smaller.

The children’s rooms are extremely spacious; you could even install walk-in closets there, as is common in America.

The children’s bathroom has been swapped with the master bathroom.

The master bedroom, dressing room, and bathroom area is also very generous.

If the bedroom were accessed through the dressing room, the wall of the utility room could be shifted toward the hallway, allowing the utility room to be larger.

Ground floor plan: kitchen, dining, living area, office/guest room, entrance hall, utility/entrance zone, WC/shower.

Upper floor plan: master and two children’s bedrooms, dressing room, bathroom, hallway.


All of course subject to costs, structural engineering, and building permit / planning permission.

That looks good, actually just small changes, but you chose them skillfully. What software did you use to draw the plans?

Nice improvements. I’m just afraid the original poster is hard to convince, which is one reason why the enthusiasm for discussing this project has already declined quite a bit.

Basically, we are now looking at a very simple standard design that has just been made a bit larger.

One naturally wonders what a child should do with almost 30m² (320 ft²)? Making it cozy will be quite a challenge. And if a girlfriend comes over later, it’s almost embarrassing to have to explain why you have more than twice as much space as she does.

@kaho674 Simple doesn’t always mean bad. The original poster was actually on a GOOD path with their last design! As @11ant mentioned, I only made a few minor changes to their plan. You usually bring character into a house through the layout of the rooms. The floor plans can be “simple” in support of that.

I agree with you, the children’s rooms are huge – maybe the partner wants to move in. These rooms could indeed be reduced by adding walk-in closets, which would also provide the extra storage space the original poster wants. I’ve also thought of another option for the attic hallway but want to see what the original poster thinks first.

@11ant that’s an outdated program from way back

That is exactly what I wanted to suggest as well.

Sorry, but what use does a child have for walk-in closets? While they are generally an option for large rooms, unless you’re a 16-year-old teenage girl who will move out in a year anyway, I doubt a child would really enjoy that. I would rather plan for a model train set or a bouncy castle.
