If building again - what to do differently?

I would not miss the electric shutters in terms of functionality even today, we rarely use them. However, I simply find the straps visually disturbing.

The electric ones have the advantage that you basically don't have to use them at all. They are supposed to go back and forth on their own and that's fine.

Of course everywhere

then these of course should even be controllable centrally from several points. We are not in the Middle Ages.

The same applies naturally to lights and alarm systems,

I find your choice of words for the question a bit unusual and beside the point… Middle Ages, somewhat misplaced.

because I consider that essential in a modern house.

In my eyes, that is simple standard.

It is not about "the modern house," what makes a house modern… uh technically up to date… two different things, apples and pears.
And it is also not about what differentiates simple standard from simply standard, at least not what for you is of course naturally simple standard.
Kati does not want a list of upscale standards here… just read again, otherwise your post will be deleted.

No, we initially commissioned 1-4... but with the goal of also commissioning the further service phases if everything develops as we envision.

Only up to service phase 4? – but you spoke of completed detailed planning, which would only come in service phase 5 (?) – and what comes next: in-house tendering and the architect may only return for construction management in service phase 8?

We are currently building, but what I would add for you: electric roller shutters with a central switch, so you don’t have to go to each one individually

Controlled as a group via PLC, with suspension of the terrace exits against unintentional self-lockout. Apart from such exceptions, switches have no place in a smart home anymore.

Of course, I stand by what I wrote, and of course it also fits the question. If such simple things were not implemented in the first house, then one should consider doing so in the next one. Which Kati also writes in the first post.

From my point of view, this leads (once again) to nothing, as it is too individual. Otherwise, all houses would already be the same.

For someone who is in the middle of the planning phase, the thread is very valuable for "checking" and "balancing." Out of sheer overconfidence, there are only two categories: "we have" and "total nonsense." ;)

Hello , You really want to know exactly ;), see the answer below

Only up to service phase 4? - but you spoke of a completed detailed planning, which would only come in service phase 5 (?) - and what then: self-tendering and the architect may only return to site management in service phase 8?

I probably expressed myself unclearly, we are only in service phase 2... I was referring to the general working method of the architect, which in my opinion leads to good results and avoids surprises. And if we are satisfied up to service phase 4, there is no reason not to commission the remaining service phases as well, including the tender.
