Single-family house with staggered floor, southwest location in Bonn

But that is from the architect. The structural calculations are done by the general contractor.

What exactly do you mean by the structural problem?

Which wardrobe

We will discuss this first draft tomorrow :)

mhh - so this will be a huge house, but you are producing a lot of dead square meters; just the area in the dining room, until the table arrives; the kitchen, the master bedroom... etc. but none of it is really generous either, it looks like it was added on multiple times and is still too small.

If north is at the top, the kids' rooms are also badly planned.

If the laundry is not washed by the staff, I would place the washing machine & dryer on the sleeping floor or at least the kitchen floor. Constantly running down to the basement would be too annoying for me; furthermore, you have to carry everything back upstairs again anyway. If you have staff, then at least provide the connections upstairs; that's how we did it at least.

Specifically, kitchen: the distance between the row & island should be about 100-130cm; the seating island 100-120 deep; distance to the wall 100-120cm. I would also make the row extra deep (75-80cm; I have 80 in front of the window and love it) meaning you need a room depth of between 360-440cm (80+120+100+120 depending on desired spaciousness).

You are producing an enormous amount of traffic space without really generating much storage; the walls for the side cabinets are also missing - preferably solved with an appliance garage or as a secondary row.

I'll leave it at the few comments.

But that is from the architect. The structural engineering is done by the general contractor.

Well, somehow the ceiling in the area of the extension has to hold. I don't consider the mini walls suitable. The bathtub is also quite heavy.

No, we have no staff :) and yes, it will be somewhat bigger. The furniture in the draft is only exemplary, also in the kitchen. We have not spoken about that in any way yet.

The children's rooms are to the east, north is to the left where the children's bathroom etc. is. I had forgotten that this is not included in the draft, but it was explained in the old ones from the OP post.

The washing machine is supposed to go to the ground floor. Although the question is whether the room there is too small to hang enough.

I still don't quite understand what you mean by extension? The upper floor in cut_3.jpg?

Statically, I consider the corner with the annex, where the upper floor then twists, to be quite a complex achievement

Although I do not exactly understand what you mean, I see here an increased urgency to fill out one or two extra lottery tickets. A house that is penetrated by a matrix of three by three cuts will be guaranteed to cost three times three times more than expected. You only need that many cuts if the planner still has to visualize for themselves how complex they have nested the building volume.

mhh - well, that will be a huge house, but you are massively producing dead square meters;

That too. The entire planning strikes me as that of a large architectural firm focused on developing plots with entire groups of houses, typically erecting such a group of three to five houses that appear individually above ground from a common underground garage (where regularly wasteful penthouses are the cocktail cherry that may cloak the motto "column grid is king").

The furniture in the draft is only exemplary, also in the kitchen. We have not talked about that in any way yet.

"Foreign" furniture in plans is regularly hidden confessions that the clients’ furniture would not fit well into the rooms and are also meant to simulate usability even where that is plainly untrue.

Even if I don’t exactly understand what you mean, I see here a heightened alarm to fill out one or two extra lottery tickets. A house that is intersected by a matrix of three by three cuts will also be guaranteed to be three times as expensive as expected. You only need that many cuts if the planner even has to visualize for himself how complex he has nested the building mass.

What do you mean by cuts? I also noticed the red lines. What does that have to do with it?

We are planning with a general contractor and therefore assume that we will receive a more or less fixed cost estimate before construction begins, which will be the basis of the general contractor contract.

That too. The entire planning strikes me as that of a large architecture firm focused on the development of plots with entire groups of houses and typically builds such a group of three to five houses that appear separate above ground from a shared underground garage (where regularly extravagant penthouses are the cherry on the cake that is supposed to mask the motto "column grid is king").

No, actually not, it’s a smaller office with more specialized projects and rather unusual in that regard, that could be the case.

"Foreign" furniture in plans are regularly hidden confessions that the client’s furniture would poorly fit the rooms, and are also meant to simulate usability even where that is outright false.

The architect does not know our furniture and we haven’t talked about it yet. By the way, we would also adapt our furniture to the rooms, or so far we have exactly one large L-shaped couch and a 2.40 x 1.20 dining table plus an armchair. We currently come from 80 sqm in 3 rooms. Prospectively we will "inherit" a small grand piano that is supposed to go into the living room. We will surely know how to use the space.

A little less ad hominem towards the architect and more focus on the matter would not hurt.
