Is the size of the house connection room sufficient?

But I haven't really thought much about that yet, as in my opinion I could also build it under the stairs.

At some point you have to know where it should go, then you have to know where the network cables should end and how long they need to be to the patch panel. If everything is supposed to go under the stairs, then do not install devices with fans. If it should be a large POE switch, then I wouldn’t want it under the stairs.

We have 4.1m2 Took some planning but basically sufficient. You just can't hang laundry. It's basically a utility room according to the minimum possible DIN.

When everything is packed as tightly as possible, cleaning is very difficult. The [Technikraum] does not need to be as clean as a laboratory, but dust and spiders also accumulate there. Especially on the pipes.

They already catch the mosquitoes for me when they feel comfortable in that dark room ;)

then cleaning is also very difficult.

This is also very important for a technical room so that no dead spider lies around. I recommend vacuuming conventionally for 5 minutes once a year. :p

Cleaning wouldn't bother me too much in the technical room now. However, if you plan it so tightly, it's best to be present at every house connection appointment. I vividly remember that fun in house #1, for example: We joked about it back then and lost a few centimeters of storage space. For you, it could possibly ruin the entire planning.
