City villa with approx. 200 sqm - without basement. Please provide feedback

Nothing against a large kitchen, but it should be ergonomic... Did you tell the kitchen planner that the window, for example, has to stay as it is? For me, this is THE killer of an ergonomic kitchen here. The island should be parallel to the kitchen line, not at a 90° angle. The ideal distance between both lines is 110 - 120cm. I would also reconsider the dead corner, it can be done, but it's better without.

The long room with the large door to the outside on the long side is not optimal for a kitchen. As I said, I would reconsider the window arrangement and, if necessary, move the kitchen line from the wall at the bottom of the plan to the wall on the left side of the plan, with a kitchen island in front of it that doesn't have to extend along the entire kitchen length. For example, I wouldn’t put an island in front of the entrance door, but pull it towards the dining table and, as mentioned, remove the little wall stubs.

Hmm, but are 3.60m in the kitchen enough? Ever thought about swapping the kitchen and living room? The living area doesn’t need such a long narrow space, and then, as Maria already did, you could carve out the toilet... Hmm, I have an idea, wait a moment, I’ll sketch it quickly, then there should also be a fairly large storage room, which you need without a basement (and with 2 children planned). Direct access to the room from the kitchen and from the garage (if it really has to be). I also don’t really understand the corner by the shower on the ground floor (in the carport). I’ll make the garage longer, so you also have storage from the garden and save a corner (cost!). Wait, I’ll upload a picture right away:

Unfortunately, my PC rotated the image, but I think you can recognize it: corner in the WC removed, the WC becomes a technical room. Storage now really large and accessible from the garage and kitchen. Garage moved forward, creating a small room at the back for garden tools. Kitchen with two rows without a dead corner, the island about 110cm deep. The hallway (now to the kitchen) can be slightly widened at the expense of the storage room, and the wall to the cloakroom can be removed, making the entrance area more open and providing more space when several people arrive at once. Access to the technical room can be from the cloakroom or from the storage, but then the storage would have three doors, which I find suboptimal (or you give up the garage door to the storage). I would also set the wall to the WC back a bit, making the entrance area simply more appealing.

Windows/terrace doors naturally still need to be appropriately revised. I would indulge in a long window over the entire kitchen workspace, set a bit lower so it doesn’t glare while working, but provides a bright workspace; in the niche, two tall cabinets can fit, between them a terrace door to the garden, and the terrace can be extended up to this door.

Upstairs, I would definitely plan an additional small room; you have more than enough space there.

Hmm, just read Maria's suggestion to put the stairs on the other side, that would also work with my suggestion for the ground floor, might even be quite clever

Currently we have a bed with 160cm width + approx. 15cm frame = 175cm. That is enough for us.

You can of course also sleep in a 140cm bed, but that’s not how you build a house. Maybe you’ll have to sell it or your children will want to inherit it. Then they won’t have a proper bed there. That would be a shame.

Overall one of the clearly better designs presented here. Basically functional, which is not a big deal given the exterior dimensions, but still. I would leave the bathroom in the east. Still smaller and another room between the children's room and the office. For that, the staircase simply goes to the other side of the hallway, in my opinion the door to the storage room also fits underneath there. The hallway downstairs is simply nonsense. The walking distance with groceries to the kitchen is not shorter than through the main entrance. With a fully loaded shopping basket you’ll end up bruising your elbows in the 1m corridor. I would completely leave out the second entrance, if you absolutely want it then put it in the storage room. The bedroom should be planned with a 2m bed, 1.60m is for newly in love couples. The kitchen is really a construction site, I also don’t imagine it cozy or practical with the floor-to-ceiling windows and the rotated island in the huge room. Think through the practical, daily workflows like putting the dishwasher on and emptying it, carrying dishes to and from the dining table, hot pans from the stove to the sink, etc. The outdoor area would interest me as well. Does the terrace face fully south? Then it’s basically unusable in summer.

My suggestion:

Kitchen with a large island (can of course be made even bigger to fit the cooktop and sink), your side-by-side fridge on the side. Adjacent to it, a small pantry. Bathroom and stairs each on the other side. Hallway removed, thus gaining an additional room:
