Single-family house of 200m² in 45° angled construction

I would understand such a kink if the property forced it - but like this? Useless corners in the house, more costs especially due to the roof construction, and a rather peculiar exterior. I don’t understand why this angle is desired. Can you explain that? Just a whim or are there solid reasons for it? Visual and noise protection is done differently, this half-hearted kink does nothing at all. Is the street so heavily trafficked? And since the property is generous, if the kink must be there for whimsical reasons, I would rather go for 90°, then you can make something of the rooms. The slants here just cost space and are useless. The most awkward I find is the wall piece in the bedroom that enables access to the second children’s room. A real joke. Honestly, you can immediately tell that this can’t be the last word in wisdom. Is another child planned? Because of the third room? I would rather house guests in the office downstairs, then they have the guest bathroom to themselves. Upstairs they share the bathroom with you. Is that intentional? And with three children, I would generally think about a second bathroom upstairs. They will all be teenagers someday and then the only bathroom is often constantly occupied... The layout of the bathroom is hopefully not serious either, right? The half-slanted bathtub without reason? I come to the conclusion that this is someone with a high affinity for useless slanting walls. No, I do not like the design at all. The exterior views are also dreadful, sorry.

I agree with Haydee by 90%. If angles, then 90°. I would be a huge fan of that immediately! If you look: The office now has the nicest spot in the whole house. A bit exaggerated for a workplace. The kitchen, on the other hand, resembles a storage room on the street and has no inviting connection to the terrace. The rest has already been said. But I find the design bold and refreshing. It is not perfect, but that can still come. Including the basement, however, this will be an expensive affair. You should state the budget before we waste time philosophizing about castles in the air.

what kind of street is it that you build in such a complicated way to shield from its noise/view, but then plan two bedrooms facing that direction? That may be unusual, but personally, I don't really like having to walk through half the house to get to the main area. The design looks as if it is an extension house. A rectangular house can also provide shielding, but I would suggest placing the entrance area more centrally and not at one end of the house. Also, plan for a nice kitchen or at least space and room for a beautiful kitchen. I don't find the bulky and boxy shape refreshing at all – the house reminds me of a 1960s apartment building that was converted into a single-family house (inside), but now the hallway, which is actually superfluous, is located in a prime spot. I think you got a bit lost in the initial thinking with the "shielding," and paid little attention to a harmonious appearance. Apparently, the plot has enough potential to shield itself in other ways. How busy is the street?

Do you really want an air heat pump or an air-water heat pump?
