Single-family house with a granny flat, 120 sqm plus a living basement on the hillside

Great, this is an exemplary response.

You think sand dunes from the garden across the terrace to the fridge are good? Don’t you have breakfast outside? Don’t you eat outside? Don’t you enjoy coffee on the terrace while the child plays?

The pantry is inconveniently narrow. Draw in shelves, cupboard, freezer. Should the kitchen be a single line? Maximize distance from car to kitchen. Missing wardrobe.

I find the entrance, staircase, door to the open space cramped. Not in terms of square meters, but in terms of effect.

Just remove the mini office downstairs. You have south-facing daylight rooms in the basement.

On the upper floor, take a look at what lies how far under the 2-meter line. Bathtub, sauna, parents’ bed. If you are a bit smaller, that might be okay. There are bumps. Don’t you have clothes that need to be hung up?

Where do you want to relax during sauna breaks?

Just skimmed through:
I would completely leave out the storage/pantry and instead make a full tall cabinet wall with kitchen there. That way more fits in, it looks better, and it’s easier to use. With a 60 cm deep cabinet, you only have 40 cm maneuvering space left.
The stairs up definitely need a window, as a general contractor we couldn’t afford once said: "Path to the light." Friends of ours have a similar staircase and have already experimented a lot with built-in lights – it still looks dark and oppressive. It’s simply no fun to go up there.
The dressing room is way too narrow! I have never consciously noticed a 37 cm deep Pax. But no clothes hanger will fit in sideways. Even if you get your clothes in there, you really have very little room to maneuver. Try recreating the distance from chairs or something. Getting dressed in the morning will become an art.

Unfortunately, the points I mentioned cannot simply be corrected without moving all the other rooms.

Regarding the basement: Looks very large and expensive for just a utility basement. I would definitely include it at least partially in the insulated envelope and heat it. Suggestion would be: office in the basement – it even has windows and a view – and spread out the rooms on the ground floor instead.

Certainly, in your eyes you have made the best out of it. The staircase is better. However, I see many things that are not pleasant in everyday life or do not work at all. The hallway is quite narrow. Ok for 2 people, too tight for 4. I don’t see any space for the stroller. I also don’t see a wardrobe closet that can accommodate clothes for 4 people. Children do have a bit more, and you can’t always go to the basement to get shoes with small children. Speaking of closets: in the dressing room there are no wardrobes with a depth of 50/60 cm, only T-shirt shelves. And in the storage room behind the kitchen, either a shelf or a freezer fits. So the storage room is pure waste of space. The kitchen is sufficient for a vacation apartment, but not for a single-family house. Your idea that Terra has proven itself in your apartment may be true, but life with a garden is different. Terra is linked to kitchen activities. Unfortunate, if you constantly have to pass by the sofa, i.e., the lounging area.

That is very costly and we wanted to keep it as lean as possible. For that we then need the basement. But currently I am thinking about a pure utility basement. That should considerably relieve the finances.

Therefore again: move one floor to the basement level, give up a basement and build each floor 10 sqm larger. Currently you are trying to make or cram a 160 sqm house out of a 120 sqm house. As a result, almost every area suffers, while the relatively large utility basement offers no compensation in everyday life and daily work.

I appreciate all comments.

My kitchen unit (single-person household) is bigger. Still, some things don't work. Check this against the actual apartment.

Therefore again: move one floor to the basement, give up a cellar, and build each floor 10sqm larger. Currently, you are trying to make or squeeze a 160sqm house out of a 120sqm one. As a result, almost every area suffers, while the relatively large usable cellar space does not provide compensation in everyday life and daily use.

That's how it is. Either you actually use the cellar as a usable cellar, then for example the pantry on the ground floor goes away.

If the cellar is actually useless for you, then make living space out of it! Depending on the terrain, bedrooms or the living area will go downstairs.

A walk-in closet in a 120sqm house with two children's rooms (and yes, also an office) is too much. You have too many rooms in a small area, all of which are then difficult. See your kitchen currently.

Alternatively: look for a level plot, it would probably be cheaper as well.

I find the location of the house and carport on the property suboptimal. The carport feels like it’s right in the middle, and because of that you position the terrace only 3 meters away from the neighbor at the edge of your property – and that on over 600 sqm! I fear that you won’t use three sides of the garden at all, but only the small part in the southwest. In my opinion, this could be optimized by having a single carport within the building area + a lateral parking space outside the building area (the house moves further up on the plan), completely giving up the carport (install a parking heater and set up a shed > the house moves even further up). It could also be possible to angle the house toward the northeast building line. Or place the carport in the sharp northeastern corner?
