House Design
Who designed it: put together myself
What do you like most? Why?
- Direct access from the bedroom through the dressing room to the bathroom
- Cloakroom niche keeps dirty shoes outside the main passage area
- Floor-to-ceiling windows for lots of light
- Straight staircase, looks modern, easier to walk on than a spiral one and better for accessibility later (stairlift)
- Very spacious living/dining/kitchen area (though perhaps too large?)
- Pantry with everything easily accessible on open shelves
What do you dislike? Why?
- Huge waste of space in the hallways

Why did the design turn out this way?
I saw a similar layout in a townhouse that I really liked at first glance. We want a generous living feel with large window areas.
Since we are planning without a basement, an extra room upstairs was created for storage, guest room, and workshop space.
Important: the bathroom layout is not really planned yet. I have inserted my first idea there but I know it is still far from a “good idea.” For now, the focus is on the basic room layout. The windows are currently more of an idea than fully thought through.

What is the most important / fundamental question about the floor plan summarized in 130 characters?
- Do you see a way to reduce hallway space despite having a straight staircase?
- What is your overall impression of the design?

I would widen all the windows by at least 30%. Or add more windows, depending on your preference. In any case, in my opinion, it would be too dark as it is.

I spent some time working on the window planning. Attached are images with the window dimensions (width x height).

At least you were consistent regarding the number of different dimensions. From this, I deduce a sill height of 98 cm (39 inches) for the standard-height windows. But could you enlighten me as to why you are specifying such unusual measurements not only for the rooms but also for the windows? On one hand, they deviate from the modular standard, but on the other, they don’t follow the rounded decimeter values you’d usually expect from a non-professional. Is that a coincidence, or something like astronomy, lottery numbers, or Aunt Trude’s birthday? Because I don’t see special prime numbers or typical standard dimensions—everything appears custom.

To what extent do specific room dimensions matter?

I have the window dimensions from the window catalog of the house manufacturer we will be building with. Or do you mean the combination of windows? ops:

Which manufacturer is that, and is the catalog available online?
For solid houses, a modular grid based on 10 centimeters (4 inches) makes sense, and even prefabricated house manufacturers usually have construction and design grids. However, I don’t recognize either of these here. Also, the window widths of 109, 138, and 175 centimeters (43, 54, and 69 inches) don’t seem to follow a clear pattern or common denominator.

The manufacturer is Schwabenhaus.
To be honest, I removed all the interior walls from the house and created a floor plan myself. Once it was finished, I first tried to reuse the originally planned windows and otherwise freely selected windows from the catalog. As far as I know, the catalog is not available online, and I don’t want to share it...

I’m also still very open to optimization ideas for the floor plan. It seems like you would change quite a few things.

Schwabenhaus is a “prefabricated house” manufacturer – that at least explains the dimensions outside of the octameter system, but I still don’t see a planning grid here (usually around 62.5cm (25 inches)). No problem. No, I’m not itching to change much: your design is already clearly more structured than what I’m used to seeing in this forum. I haven’t noticed any major mistakes so far.
