Bauhaus concrete villa with core insulation - experiences

I know how much space KNX requires. We have more area and therefore probably more lamps, blinds, windows, sensors, etc.
Irrigation probably also runs via KNX. But I first have to take a look at the Gira module.
My parents have a bigger house but haven’t gone overboard with KNX. Two of your cabinets are full. We’ll probably end up at about this scale.
What do you mean by devices? Actuators or individual channels?
What kind of system are you using (server, visualization, etc.)?
Additionally, there are the house connection (3*150 amps), normal fuse cabinets, inverters for photovoltaic, components for locking systems, etc.
You could probably arrange it all in a smaller space, but I’m a fan of reserves and if you have to work on it, there should be some room available.


Regarding toilets, our ideas seem to differ.
We currently have 3 toilets. The most used one has no window. And I have never thought about whether it’s necessary or sensible. With other rooms, a view is more important to me.
I can’t fully accept the argument about ventilation either. If you open the window when there is no wind and don’t create a draft by opening the door, the air exchange is low. Opening the door would miss the point.
Our toilets are planned with an air exchange rate 10 times above the norm. You can’t achieve it faster even with a window.

Toilet on the ground floor:
It’s not just a guest toilet but also for us. We don’t want to always have to go up or down a floor when we’re in the living room.
If a guest is mentioned, they’ll just have to find another one.

Toilet on the upper floor:
You immediately recognized the problem.
Even with silent pipes and such, you have the flushing noise. But for several reasons, we left it like that.
Currently, we also have a toilet next to the bedroom (no silent plumbing…). My wife occasionally goes to the toilet at night and turns on the light. I don’t notice because I’m a very deep sleeper. My wife sleeps with earplugs because I snore. So it’s not a problem if I ever have to go.
In the new house, the lighting will be controlled via KNX. Steffen80 surely has this too. After a certain time and dropping below a brightness threshold, the light will only brighten to 10% as soon as someone gets out of bed. This happens along the entire path to the toilet.

Seems the architect likes to design bathrooms without windows in general. Yet that is precisely where people like to open the window. And in such a luxury villa.

You can drop that dogma especially in a villa like this, since technical solutions (which need to be paid for and can be) allow far different options than just breaking a hatch into the cave wall.

Now the anti-window excuses don’t hold up for me. To me, that is always poor planning. After all, we are no longer in the Middle Ages. Sure, you can solve this with ventilation. But it’s not just about fresh air in a room. The feeling of being trapped, freedom, openness, and above all natural light are crucial. And that is true in every room I use daily – even in toilets, dressing rooms, utility rooms, and pantries – just to complete the list of frequently bunker-like rooms.

That’s also something I’ve noticed. In this luxury giant, I definitely would have planned 2 bedrooms. One large and one small. Many couples don’t sleep together when they get older, because at least one of them is too loud at night. It’s the same with us and I really love my husband. But that he expects me to wear earplugs at night, that would be a strong piece.

How is the noise level, especially at night when everything is quiet, and the perceived airflow with such a strong ventilation?

I find mini toilets without windows cramped. It has something of a small prefab house from 1980 and no matter how nice, the feeling of a public toilet.

You can drop the dogma especially with a villa like this, since technical solutions (which need and can be paid for) allow completely different possibilities than just cutting a hatch into the cave wall.

True. I would also plan with windows... but more for light and "spatial feeling." You don't need that for ventilation. No one opens the window here. After the "k*****," the controlled residential ventilation is anyway much faster at air exchange.

@TE: I meant devices. But here everything is connected via the bus. Air conditioning, controlled residential ventilation, water softening, Vaillant boiler and so on. There are definitely a few hundred actuator channels. Group addresses are currently about 4000. We have 71 light outputs/lamps (not all via DALI). About 100 1-wire sensors are in use. The visualization uses smarthomeng with smartvisu. I'm not a fan of the Gira Server. Pure "KNX logics" mainly run via MDT logic modules (quite a few of those). We don't use the visualization that much... mostly we use Alexa, which can control almost everything here (not the garage door, that’s a bit too hot for me).

I hope you have a good planner for the KNX topic. I planned everything by myself, and that was good. There are still a few houses with KNX on our street (they had everything done)... that's no comparison. They all had no good planner...

There are hardly any good home automation planners. Most KNX installers (at least here in West-Th / East-Hes) are either trained cable pullers who are stuck IT-wise somewhere 10 years ago. Alternatively, the industrial outfitters / TGA offices lack the touch and experience with the nice things in the home sector. I only see "do it yourself" here.

OK, if all the house connection stuff, power distribution, etc. is included, the size fits. You can work with that then. I had placed it in the adjacent room.

Among other reasons, I completely skipped it. Prefabricated house construction from the nationwide general contractor and their moon prices just for the wiring + no time to do it myself were added to that.

Again about the WC : On the ground floor, I simply miss the "just around the corner" factor in the literal sense. I don't see odor as a problem with your controlled residential ventilation planning. The "bunker factor" can certainly be minimized with top equipment in the form of lighting effects, possibly an electronic large image frame, etc., and it would bother me less as well. Especially the direct connection to the kitchen does not seem appropriate to me in the overall object. At my parents' place, the kitchen is a walk-through room to the bathroom (without WC). That is an old building from 1913. But that is no longer up to date and it can certainly be done better.
