Floor plan design single-family house 150 sqm - tips for improvement?

I think city villas should be prohibited on slopes. Except for those that are only single-story from the slope side. For all other houses: adapt the roof design to the terrain.

A shed roof wouldn’t make it any better for us either! There is always the roof terrace, and adding a pergola to it certainly doesn’t make it look better!

No, I meant
Living will be Child 1
Eating will be Child 2
Kitchen becomes utility room storage and upstairs reversed

I also don’t know, the ground floor is packed and upstairs there is space. Especially when the older one moves out. Whether in five or 10 years. You have bigger children, I think you have to think differently there. You don’t have a toddler who goes into the garden at the first ray of sun and a parent has to keep an eye on them. You are now more in the phase where the buddies come by at 10 p.m.

I’ll throw everything overboard now. Parent, 1 children’s room, cooking eating on the ground floor
Upstairs 1 children’s room and the living room on the large roof terrace. When the young crowd comes in the evening, you can sleep peacefully downstairs. If the little one sleeps downstairs, you can enjoy a glass of wine in the lounge upstairs

I would never leave things like vacuum cleaners etc. in the hallway.

ever heard of cabinets? I even "marked" them in the plan whether you have cabinets for cleaning supplies, buckets, brooms, and vacuum cleaners in the separate room or the cabinets are in the spacious hallway (all our cleaning stuff including the vacuum cleaner is in an "integrated" cabinet in the hallway that has two doors and is about 60x100cm, it even contains the towels for the bathroom). You could even hang large mirrors on the cabinets. The kids will thank you for that likewise, it could be a kind of play hallway for the younger child. Or you could install a window seat there, or, or, or... and the 14m² is including the space for the stairs, which alone takes up not quite 5m²

Haydee, that’s really kind of you, but in the long term, with regard to age, we want to keep our areas on the ground floor.

Everything is just difficult for us: corner plot, sloping site, single-story construction and not least the room requirements. As already mentioned, both variants should be optimized as much as possible.

In the ground floor (variant 4) you could still pull the master bedroom a bit towards the terrace in order to perhaps make the bathroom a little wider.

I am not even at the upper floor yet!

You always start with the same basic layout of 5.9 to 6.3 m width for the living/dining room, almost a square together with the kitchen ... and that is usually the most unfavorable room shape for these spaces.

Is it just me or wouldn't you arrange it rather like this:



You can forget about access to the utility room, that's nonsense, as Yvonne already said. You always have to run through the whole living room with your clothes to then get the dirty shoes into the cloakroom. Besides, the sun needs to get into the kitchen.
Otherwise, I don't find the design that bad. The lack of a retreat area in the living room is a shame. Direct access to the kitchen would also be important to me, but it has to work without it.
Laundry would definitely be in the storage room upstairs for me. Always running past the cooking pot with the smelly clothes wouldn't happen in my case.
