Collect floor plans of 150m2 for our house

The right side (bathroom, living room, bedroom, stairs) feels very cramped to me.

Bathroom
no possibility for a cabinet
only a small washbasin possible
narrow passage

Bedroom
access to the back bed is too tight

Living room
couch in front of the terrace door
dining table in front of the corner I don't like

Stairs
does the stairs even fit there?

There is no guest toilet on the ground floor

Overall, the measurements are missing.

Mmh, well, moving furniture is just fuss, in my opinion. Everything fits in. See for yourself.
But I totally forgot the guest toilet. Hehe - just kidding. Damn it, use your own bathroom at home!
Upstairs, you could move the laundry to add it to the bathroom. Downstairs, one side of the stairs for the utility room.
But it's all just playing around, without the guest toilet, start over again... Tralala

Oh, the staircase should fit 205 x 245 opening. At least theoretically in the staircase 1x1.

Did you put the toilet under the stairs now? My parents solved it that way, with a U-shaped staircase that was built. It's sufficient for a toilet and a small hand basin, only the door hinge had to be placed towards the hallway.

No no, there is no toilet under the stairs. We have to toss the draft in the bin.

I'm tinkering. I have a question. Can you fit a wardrobe under a half-turned staircase with a room height of 2.50m? Staircase opening 2.25 x 2.25m. So, a square. Does anyone have experience?
