Electrical planning: Where to install sockets, LED and LAN outlets?

You can invest quite a lot of money in electrical work. So check whether some ideas are really going to be used.

- Classic: socket in every window recess

I know: for the Christmas lights. I forgot to plan for them - and I’m actually missing only one! Do people really still plaster the windows with string lights or set up those "what are they called again, wooden stands with 5 lights that grandma already had"? Because with 10 windows, it can be over 500 € burned by a general contractor.

- music preparation for the terrace?

In summer for a party, the indoor socket with an extension cord is good enough – constant music is not appreciated in the neighbors' gardens.

... in the Ore Mountains, the window reveal socket is mandatory and not for some kind of Industry-5 little lights chandelier, but for proper Schwibbögen.

And, terrace .. music or even TV connection ... I’m just saying "terrace viewing World Cup or European Championship" is already great and it’s also great if no cable has to be run from inside to outside anywhere.

everything from me were just ideas, no obligation. I also don't have any speaker cables outside, but the socket in the few windows really wasn’t a problem. if it were according to your logic, you wouldn’t be allowed to put a socket in every corner either... as I already wrote in the 1st post, there aren’t too many sockets, only too few. now it’s a few meters of cable, later tens of thousands of euros in effort... electrical cables can be very well installed as a DIY project...

Schwibbogen! Thanks, that's it! I rather advocate for a socket in the upper area for a hanging string of lights

"Terrace viewing World Championship or European Championship"

Yeah, everything is allowed there anyway But honestly? Anyone can do it with a tripping hazard - the TV has to be pushed out anyway . What I want to say: small things also add up, and it would be a socket to which nothing would be permanently or regularly connected. In this respect, you shouldn't overestimate nice and expensive details.

if we followed your logic, you wouldn't be allowed to put a socket in every corner...

Exactly, we haven't done that either, since I don't find sockets and switches particularly aesthetic. And I have to say that we hardly have too few, except that in two corners one each is missing... and at the kitchen counter I am missing a second one. However, many are currently unused. Behind the TV we have 3 too many: roughly well planned with the switch, but did not consider that the receiver etc. are connected to this one power strip.

But we are just collecting suggestions for OP anyway, whether they should be implemented is up to everyone to decide.

For a party in summer, the indoor socket with an extension cord will do

A socket on the terrace, switchable from the inside, is part of even the most basic equipment packages, right? I certainly wouldn't want to do without it. Then there are electrically operated garden tools (corded, the classic used to be: lawn mowers. I don't know if today there are only battery-powered devices for small gardens and the next level is the ride-on mower with a 5 L V8 ...). Anyway: power outside -- a must.
