Why is the design as it is now? Previously lived in an old building with 3.5 m ceiling height and very large rooms; tried to at least partially reproduce the rooms; bedroom is deliberately located south-facing because of the nice view

Are children planned? I'm not sure; even though there are two rooms upstairs, I can't tell from the suggested furnishings whether these are supposed to be children's rooms. If children are planned, a quick question to consider: how often do you look out from the bed to enjoy the view? How often do you spend the day in the bedroom? How often do the planned children spend time in their children's rooms?

If no children are planned, I would also indulge in the beautiful location for the bedroom, but then the rest of the room layout doesn't make sense to me. It would be good to know what functions the other rooms are supposed to have. Furthermore, I would then opt for a slightly more luxurious bathroom.

Guest room upstairs, guest bathroom downstairs. I find that unfavorable. Better to plan the office upstairs and the guest room downstairs. Otherwise, the guest will also use your bathroom.

Is the garage accessible through the carport? If two parking spaces are required, that would not be allowed in our area, as each parking space must be freely accessible. However, I know that elsewhere this is okay. But check! And consider: does it make sense this way? What is the situation on the property? In principle, it is more practical if each parking space can be used without first having to move the car in front.

Terrace boxed in by greenhouse and conservatory. It might be nice when it's cold, but, for example, in a summer like this, the terrace feels suffocating because there's no breeze. And if it's too cold for normal terrace use, you also have the conservatory. Is this supposed to be a conservatory belonging to the living area or a cold conservatory?

Overall: for 190 sqm, I don't really like the floor plan. I would expect a bit more spaciousness and sense of space.

One should plan differently if the house is intended to remain child-free (then I would probably do something with an open space here) or if kids are planned. But even then, it just seems like little boxes placed next to each other.

The guest room is actually the office; the labeling is wrong. Parking space is a good point; we've never had more than one car, so that problem hasn't come up yet, and a double garage would be that wide. Children's room, no idea - not currently planned but you can't rule it out either; the problem is that we have a fully furnished apartment of that size but it's completely differently laid out and something like that can no longer be implemented today (basically like a J bungalow).

You have a slope. Where is it planned here? Planning slope properties yourself is, as a layman, the nonsense of the century. Take your land and go to an architect with it. I don’t see the 190m² for 450K by a long shot, because you have to set aside a pretty sum for the earthworks.

Furniture can be rearranged and gradually replaced. Don’t make the mistake of planning your house around the current furniture. Plan your house the way you want it and most furniture can be accommodated somehow, some will be replaced immediately, some gradually. But building the apartment you currently live in, I consider the worst way to plan your dream home.

If children are not really planned but also not completely ruled out, I would think about a flexible floor plan: Office on the ground floor, and on the upper floor a separated area with one or two rooms and a smaller bathroom. It can first be used as a guest area and then possibly become the children’s area while the guest gets the office, where they have to use a sofa bed; you don’t seem to have that many guests. You can also consider building a large gallery and at first one room for max. one child, but with the option to possibly create a second children’s room from the gallery. This way you would initially have a beautiful, spacious feeling that 190sqm would justify for 2 people, but also the option to switch to a family home. In my opinion, the worst thing is to plan two children’s rooms now that will never really be used and thereby miss the chance to create a real dream living space for two people.

By the way, with 450,000 Euro you won’t really make it for 190sqm. There is also a slope... which makes everything more expensive. But there are also other planning possibilities and opportunities.

Think about a room concept and off to the architect!

I don't see the slope in the design.
