My house planning? Criticism welcome! Improvements?

Hello,

since I would like to design my house myself, I am now also posting my draft here. Of course, I will go to a builder / structural engineer next, but first I would like to put my own ideas on paper.

A few key data about the plan:

- Plot size: approx. 1350m² (left west, bottom south)
- Hillside location (zero point is in the west) approx. 6m slope
- Planned is a solid house with 50 cm bricks
- Garage is thermally separated from the house
- Heating: Geothermal with deep drilling possibly with additional solar heating
- The street on the west side is only a 3m wide dead-end street and leads only to another house
- Light wells are not yet in the plan
- Between the hallway and living / dining room there will be a sliding door
- Roof has 45 degrees and should have a ceiling height of about 2m at the top in the middle for the attic, so that a room can possibly be accommodated in the future
- Knee wall is 1.4m in the upper floor
- To the left of the fireplace on the ground floor there is a skylight installed so that light from the living room falls into the hallway
- Bay window should be equipped with venetian blinds

- One possibility would also be to extend the upper floor over the bay window:
1. Only balcony
2. Additional room

- Kitchen is only furnished in terms of shape, without appliances, etc.
- The fireplace is supposed to be a glass corner fireplace (e.g. from Brunner company)

Questions:
- What do you think of the layout, what would you improve?
- Where is the best place for the garbage bins? (in the garage or external?)
- The chimney pipe goes out at the ridge, does this cause a problem?
- Would an extension of the upper floor over the bay window be useful?
- Is one roof window on the north side sufficient for the upper bathroom?
- What can I still improve with the windows?

Best regards
Wolfgang

Same layout, same size? (Sorry, I have no patience to look at the measurements)

You can tell when a layman starts planning (Take one of the most impractical staircases... for example the kind you might find in a terraced house)

A hillside house screams for an architect - you don’t really want to put a 1950s settlement house on a hillside plot, do you? At least, that’s what it looks like. It can only be wrong to tackle the subject of "hill" on your own.

Yes, I have seen the floor plan as well. We have roughly the same layout. However, the size differs, and I also have a pitched roof, so it is one and a half stories. I forgot to mention that the property is located in a rural area and all the surrounding houses also have pitched roofs, and the landscape planner does not want any other roof shape either. I have also heard from a fellow builder, who only took a very brief look at the plan, that staircases with landings would be more sensible. However, the half-turn staircase doesn't bother me. It is not supposed to look like a house from the 1950s anyway. I want to have a modern pitched roof house. I can mostly level the slope and put up a stone wall towards the street at the front. Am I completely on the wrong track with my planning now?

Hi, I don't think it's so bad if you already start thinking about the house yourself. It's also not a complete failure, as I've seen with others. Especially on a sloped site, a professional can achieve much more. I definitely wouldn't save money there! What catches my eye quickly: - The entrance area is too narrow for me. Where do I put my shoes, bags, and jackets? What if guests come? - The staircase looks so small. Is it properly fitted? - That closet thing in the bedroom creates a dark hallway entrance. I always find that bad. - Is the bathroom missing a window? - The door to the other staircase upstairs is nonsense in my opinion. - You carry your laundry over two floors for washing. Very annoying. I would at least try to plan a laundry chute here. - Where exactly do you come out of the staircase upstairs? It somehow looks like you run into the wall - at least partially. My tip: Definitely do not show the draft to the architect, just list the wishes.

The door at the top of the stairs is not allowed. Stair steps on the slope are difficult. What height do you have at the outermost point? People usually walk on the outside, as the steps are wider there.
