Land planning - which house type/size is most sensible?

Example: I said I don't want a straight staircase to the upper floor that basically starts right at the front door.

I understood that you want a straight staircase, but it should not start at the entrance.

That's how the general contractor architect must have "understood" it too. I understood it differently, and if my interpretation is "correct," it would be better phrased in "two parts," namely "no straight staircase," "and it should not start at the entrance either." What exactly is it about: the start "not feeling like it’s slammed right behind the door" or "technically not in the mud zone" (which in my opinion only exists here in the forum, I still belong to a generation that instinctively uses shoe scrapers, doormats & co.—simply because people used to make sure that Hans learns it when he’s little).

if my interpretation is "correct", it would be better formulated "in two parts", namely "no straight staircase", "and it should not start at the entrance either". What exactly is it about there: the start "should not feel like it’s slammed right behind the door"

Exactly, that's what it's about for me!

We were at our preferred [GU] today. Oh man, that was pretty sobering.. He said that he assumes the plot is not developed because it was a garden before and only now a building plot. He also suspected that quite a bit of earthworks will be necessary. Well, better to expect more first than to experience a nasty surprise later.. Of course, I can only research that starting Monday.

But the media connections are right there on your street. There are houses on both sides. Such a development is annoying because it obviously costs money, but it's not the end of the world. We built on a field and had nothing but electricity. There wasn’t even water or telephone on the street. So don’t be shocked by something like that right away.

I am kind of shocked because I assumed the plot was ready to build on. The seller also declared it as developed..

I'll just ask him again.

Deer OR telephone, you have to choose

That looks like the fine distinction between "developed" and "fully developed" :-(
