Idea collection for floor plan

I find the hallway too small for 4 people anyway. The partition to the open-plan area could be extended further down, up to the kitchen niche wall.

Although this change would make the hallway larger, it would not increase the truly usable space for clothing, etc.?

Hmm, that is very bold, extending the storage room up to beyond the 3rd step of the stairs. What ceiling height is planned there? The headroom on the stairs will become very tight.

Is south at the bottom of the plan?

What can be moved closer to the windows?

Does the balcony have to be that large?

The open space is 575 cm deep at its deepest point. You planned the kitchen area with a 60 cm countertop, 90 cm aisle, and a 90 x 150 cm island. So 210 cm depth, leaving 365 cm towards the bottom of the plan ... about 100 cm of that should be traffic area. So for the sofa corner, only 260 cm remain. The sofa now drawn measures approximately 83 x 210 cm proportionally.

Regarding the hallway, if you don't leave that stub there and make the entrance flush with the kitchen niche, you have slightly more storage space but, above all, can move around better there.

Hmm, that is very bold to extend the storage room up to above the 3rd step of the stairs. What floor height is planned there? The passage height on the stairs will become very tight.

Yes, it will probably become even a bit less. These drawings of mine are of course only sketches for the architect.

1. Is south at the bottom of the plan?
2. What can be moved at the windows?
3. Does the balcony have to be this big?

1. Yes! (Almost exactly)
2. Actually nothing. What would be desirable?
3. Yes, unfortunately. Only 250 sqm of living space may be built on 2 floors.
The building volume is 300 sqm.

Well, these are just questions for now... we don't know the ground floor layout. Somewhere you also wrote that the load-bearing walls are fixed. That leaves little to no room for maneuver. And the question is, for example, what you would put in the newly sketched storage room? Window sill height?

The biggest issue I see is in the bedroom:
- Wardrobe depth with doors, presumably sliding doors, otherwise nothing works with nightstands etc. = 66 cm (e.g. at Ikea Pax)
- Bed width 180 cm plus frame = 190 cm
---------------
= 256 cm

That leaves 60 cm aisles beside the bed... that's really tight in front of the wardrobe. And the wardrobe can probably be a maximum of 200 cm.

Well, I don’t follow every trend... At least not immediately.
But I also think a reasonable hallway/entrance area belongs in an apartment. I have small children and simply couldn’t imagine sitting on the couch in the evening with friends, chatting, laughing... And my boys are supposed to sleep behind a door or a wall... Doesn’t work!

This is not a trend. I almost exclusively know older high-rise apartments/residential areas with open living spaces, where on one side the bedrooms branch off, and on the other, in the front area from the hallway, one or two bedrooms.
In this way, the bedrooms are separated, for parents and children, thereby preserving privacy.
Certainly, I agree with you about the hallway that should separate the entrance from the living area.
However, I must also say that these apartments do not have truly open kitchens: usually small U-shaped kitchens with sliding or glass doors.
These apartments are not small, around 100 sqm or so, intended for families with several children.
Off the top of my head, I can think of 5 residential areas... from the 70s as well as newer ones.

Classic 3-room apartments usually have a hallway that connects each individual room.

And here... already says it: square layouts are hard to zone.

Basically, the upper floor depends on the ground floor: so I don’t know if you can consider the upper floor separately now, window positions also play a role.

The ground floor is specified by the financier. I think with good arguments one could also change the positions of the two walls once again. But on the right side, I actually find it quite good. The bedroom situation is not satisfactory, I agree with that too. Can it only be done with more width?
