Bungalow with developed attic 135 m² (amateur) draft please evaluate

Hello everyone,

I keep reading that you don’t really need to deal with the floor plan in detail before you have been to a construction company / architect, because in the end something different comes out anyway, but I just can’t help myself and want to think through as much as possible ;) and I don’t want to have to suddenly throw everything over after the first offer meeting if something just doesn’t work at all.

House design
Who designed it: do-it-yourself (Excel)
What do you particularly like? Why?: I'll write everything that was important to me:

- I find bedrooms and bathrooms cosier in the attic, and also you don’t have the feeling that someone could walk past the window at any time, purely a feeling thing

- Bedroom as far away as possible from the utility room because of noise and not completely in the southwest because of heat in summer

- Bedroom fairly spacious (even if many probably see the bedroom only as a sleeping nook). I am currently very annoyed in my 12m² bedroom that you constantly bump into things and look at the closet wall, barely have space to dress and it is just a dark room to sleep in. Also, I think it’s a good idea to have an alternative room in case you ever need space from (yet to be found) partner or the lady wants to quietly throw down her yoga mat :D

- Bathroom also big enough with open shower without glass wall (I don’t like that)

- Covered terrace in front of dining/living area, because I’m not a fan of direct blazing sun (not a sun worshiper) and you can use the terrace even in not so great weather. Whether the lighting conditions are sufficient, I’m not sure yet

- No room doors / walkways in dirty area

- Stairs not in the dirty area and as central as possible

- Dormers for more space and the look from outside (+general advantages of dormers)

- Living/dining area in one room, kitchen separated from it

- at least 1 additional room for office/hobby/child; ideally 2

- Roof slopes usable as storage

What do you not like? Why?: since it is my own creation, not much so far:
- Entrance area perhaps still a bit too narrow and maybe it could be somewhat separated up to the stairs(?)

- Regarding the bedroom I'm not sure whether it is statically feasible without additional supports (bothers me in terms of spatial feeling)Architect/planner price estimate: not yet available [B]
[/B]
- Personal price limit for house including equipment: [B]320k[/B]
Preferred heating technology: [B]heat pump or gas (still uncertain)
[/B]
If you have to do without, on which details/extensions
- you can do without: [B]canopy over entrance area, storage room; I have already left the rest out for cost reasons anyway ^^[/B]
- you cannot do without: [B]fireplace, bathroom with bathtub, covered terrace
[/B]
Why did the design turn out the way it is now? E.g.
I am building the house for myself alone first, I am single but want to plan the house so that it is still comfortably habitable for two up to a maximum of three if necessary.
I can only build a bungalow on the plot and played around with floor plans on one level, but couldn’t really find one for me that also fits in the building window. I am also a fan of attics (as long as these don’t become saunas).
Originally, I assumed that I would get by quite well with 120m², but on the whole it has now become about 135m² to feel really comfortable with it.
I had a hard time fitting the rooms properly because of the many slopes and moved a lot, but either a room had too many slopes or it no longer matched the ground floor (e.g. utility room under the bedroom).

What is the most important/basic question about the floor plan summarized in 130 characters?
[B]Since it is my own design, I want to know if there are any glaring errors that are objectively just nonsense. Details or purely personal taste should be left out.

PS: I hope the dimensioning is not so detailed at this stage, otherwise I will try to add it later.

hm... EG doesn't look wrong at all now, but without dimensions it is not really assessable. I find it better with rough drafts to simply fall back on pencil sketches on graph paper to better judge proportions.

In the upper floor, the sloping roof will overwhelm you and make furnishing for your intended use impossible. The bed cannot be used from one side. The toilet not at all. The bedroom will be what you don't want, rather small and cramped without freedom of movement. There will also be no space for yoga unless you only move by crawling.

If you want to extend an upper floor, I would opt for a gable roof and enlarge the KS inside. Actually, you would have to build up to 2.30 meters in height above and seal off the rest behind it.

Possibly fall back on a staggered shed roof: one side raised with a comfortable living height, the other side, for example, open to the EG or as a low knee wall.

No toilet at all. The bedroom will be what you don’t want, rather small and squat without freedom of movement. There won't be space for yoga either, unless you only move by crawling.

Although you are of course right that it looks squat and cramped, I think you missed the dormers, didn’t you? As far as I understand, the toilet should work. But the wardrobe is a problem, right? What also seems rather questionable to me is the platform staircase.

Right, the toilet was a dormer. I always rely on my memories of the drawing on my phone – things often get lost there [emoji16] The room at the top left would only have about 2 sqm usable in front of the door...

I would only plan 2 rooms upstairs: 1x bedroom, 1x bathroom. Simply because there is too little space for furniture. Dormers won’t help with that either. The suit has to go somewhere. And if ball gowns or even wedding dresses have to go in there... That’s why a longer wall within the 2m limit is needed. Or do you want to crawl into the closet for the rest of your life? I would also soften the slope with partition walls to about 1.5m or so. Just roughly indicated in the sketch.

I think EG is cool. So plain and simple that you can pee on it in the snow, as the saying goes.
