Floor plan detached house, 2 full floors and a recessed floor

The corner spaces behind the staircase are caused by the prescribed recessed setback of the top floor on all sides. [...] A staircase against the outer wall is not feasible, [...] alternatively, a staircase in the middle of the ground floor...

All misconceptions, but architect training is not part of my unpaid efforts here. With a little more thought for a few pennies, he can figure that out himself. Consistently identical stair floor plans and a top floor recessed on all sides (or a roof slope) do not fit together. However, the cause of the unsatisfactory result is not the setback, but the lazy architect.

The top floor in wood is currently rejected by the general contractor.

Is it your house or his? - whoever pays, gets to order!

I will work through your criticism and/or confront the architect with it.

Which phase of the project are you currently in? – He will hardly want to go back in phase 3 just before 4.

Many thanks to you three (ypg, haydee, 11ant) for your comments.

Basically gladly, but here I really struggled with myself whether it was even worth commenting anymore. I cannot hide that I was not insignificantly disappointed: You announced grandly and at length that you had used the long interim period for substantial improvements. The long period was correct, so I had to look back once not only in my memory but also in the thread. And what did I see? – that instead of the hammer drill you only took the nail file in hand!
Of course, you can also build it as it is now. But for that, you could have avoided two months of the thread gathering dust, you were already that "far" before :-(

The long time was true, so that I had to scroll back not only in my memory but also in the thread. And what did I see there? - that you took the nail file in your hand instead of the rotary hammer!

That's how I felt it too.
"The stair position makes the house"
In this case, it is not placed correctly. And no: it does not go into nowhere if it is positioned correctly. If the exterior walls lie on top of each other in the west, it should also be found here. Then with large windows on the upper floor/attic, which the ground floor also benefits from.

The wardrobe and the living room for 6 people would be far too small for me!

All misconceptions, but architect continuing education is not part of my unpaid work here. With just five cents more thought, he can figure it out himself. Consistently identical stair floor plans and a uniformly recessed setback floor (or a sloping roof) do not fit together. The unsatisfactory result is not caused by the setback, but by the lazy architect.

Can you give a tip on how you imagine it? I am just totally curious how one could solve that.

In this case it is not positioned correctly. And no: it does not vanish into thin air if placed correctly. If on the west side the exterior walls are aligned above each other, it should be found here as well.

Unfortunately that is not the case, even the walls on the west side are not aligned above each other?

Unfortunately, this is not the case, even the walls on the west side do not align?

Don’t you wonder why?
Would you randomly place the exterior walls?
Would an architect or planner arrange the individually offset levels so that there is no clear line—for orientation of the bricklayer, structural engineer, and not least, to accommodate a well-placed staircase that doesn’t create any awkward niches?
Leaving aside the energy aspect of creating as many exterior walls including ceilings and outer edges as possible?
Houses with recesses or setbacks or offset cubic construction are usually not random. Also, to the observer, there is at least one clear line so that the house does not look restless or arbitrary.
My tip regarding the staircase arises if you raise the thermal envelope on the west side uniformly upwards, to achieve light and openness through a west-facing staircase connecting three floors. The garage then helps to create a visual break.
If an offset is unavoidable, I would make sure behind the staircase there is an open space to visually and lighting-wise separate the house and the staircase.

For me, the whole design is not a masterpiece but thoughtless arbitrariness.
Starting with a basement that is not included in the room program, continuing with the exterior shell, row house-style comfort through window arrangement, the two arbitrary walls on the ground floor, relatively large rooms, and ultimately the most important part: the staircase.

Can you give a tip on this, how you imagine it? I am just totally curious how one could solve this.

Then contact me externally - as I said, architect training is not my job here, so I don't want to draw it out here ;-)
