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?

Oh my God, he called my design "praiseworthily clear" :eek _O Just kidding!

I looked into split-level houses but unfortunately realized they are not suitable for us. I find them beautiful, but I don’t want to constantly use stairs in my daily life.

Since I’m a complete beginner, I don’t understand what is meant by "building on the plot at the terrain adjustment level." We have now given the floor plan to the architect. I requested that we also get a design showing the slope changes. I’ll probably wait for that and then share it with you all.

The "ancient Greeks" don’t just offer Pyrrhus as an example; Sisyphus also serves well as a warning. "Building *with* the plot" means accepting a practical partnership rather than exhausting yourself and your budget by moving large amounts of earth. In this case, that might have meant designing a split-level house. You don’t have or want that. So, I suggest Plan B: minimal invasive terrain modeling—embedding a level house so that the surrounding land gently slopes to it, but not much more. For example, I would willingly consider whether two or three steps between the living room and terrace (and/or partially embedding the house, perhaps using three-quarter height instead of full-height windows) could smoothly solve the issue. As an alternative, investing a sum equivalent to the kitchen, bathroom, and roof costs solely into reshaping the terrain seems worth considering. However, to make such considerations concrete, you would need a drawing of the terrain’s slope relative to the house sides. So far, the simplest usual elevation views are still missing here.

Yes, I’m sorry about the facade views, but currently we only have them from the developer’s "base model" and without any site planning. Since we have significantly altered the design, including its size, it doesn’t make sense to share those. The architect just received our "go-ahead" for creating the plans yesterday.
I’m just going to wait and see what she recommends. Maybe we can save some money through our own work; we’ll see.

Developer? – I often mention that a "prefabricated house" manufacturer basically also acts as a general contractor. But developer? – that would mean you bought the house together with the land from them (so the site integration would not be your concern). I’m not familiar with that – I know of a "land service," yes, but in a way that the house buyer purchases the land separately (directly from the previous owner).

Okay, I obviously used the wrong term. What I meant was the basic model from Schwabenhaus. We are not getting our plot of land from them!
