Electrical planning stair area + outdoor facility

Hello dear forum participants,

I am currently working on our electrical planning, somehow everything is getting more and more colorful on my plans
I do know that you need a switch to get light, also that power comes from the socket, but two areas are really puzzling me:

1) the outdoor area: we want to illuminate the front and back of the house each with one spotlight. Of course, outlets will be planned that can be switched from inside (the front door).
A carport is planned (with later lighting, motion detector?), and the garage, which is 2 meters away from the house, should also get power for later (sockets, light, possibly electric shutters). Furthermore, the garden should of course be illuminated later on.
Question: Is it enough to tell the electrician these needs? Will one supply line to the carport, another to the garage, and a third supply line (cable) towards the garden be installed? Can several lamps be installed in the garden from one cable?

How does it work if the lighting is to be upgraded accordingly only later (after moving in)?

2) the stair area to the upper floor: the stairs lead (unlike most) from the open living area to the upper floor. The living area is open at the top (no intermediate ceiling). Going up the stairs, you come to a small gallery (hallway).
On the other side of the stairs below is a wall where 2 spotlights are planned. Somehow I have planned now: light switch downstairs for stair spotlights, light switch upstairs for the gallery. Isn’t that too complicated with all the switching? Should one rather illuminate the gallery upstairs together with the stairs? I have already thought about a motion detector at the base of the stairs, but there is also the living room, so the stair light would always come on when passing by. In the open air space hangs the lighting of the living area (3 large spheres). Could this lighting possibly be enough for the stairs? So that the spotlights could be omitted. Then, however, the main light in the living area would also have to be switchable from upstairs?!

Can anyone give me a tip on how best to solve this?

Hello,

1) the outdoor area: we want to illuminate the house at the front and back with one spotlight each. Of course, outlets will be planned that can be switched from inside (the front door). A carport is being planned (with later lighting, motion sensor?), and the garage, which is 2 meters away from the house, should also get power for later (sockets, light, possibly electric shutters). Furthermore, the garden should naturally be illuminated later.
Question: Is it enough to inform the electrician of these needs? Will one supply line be laid to the carport, another to the garage, and a third supply line (cable) towards the garden? Can several lamps in the garden be connected from one cable?

If you communicate your needs like this to your trusted electrician, this is actually no problem for him; if it is, quickly find a new one.
Still, you can do the installation work yourself and save the money.

Basically, you need an underground cable for the wiring, as it will be installed outdoors. For your facade lighting (not the carport), NYM cable could also be possible, but personally, I don’t think that’s so great.

Garden lighting:
For garden lighting it could be NYY-J 3x2.5 mm². It depends on cable lengths and power consumption of the lights. Maybe 1.5 mm² is also enough.
You can lay the underground cable directly in the ground; ideally, you place a yellow warning tape with the caution “high voltage cable” or something similar above it so that when digging in 10 years, you won't hit the cable by accident. (approx. 60-80 cm deep, frost protection level)
You start laying from your house distribution box, over the ground to your first point, make a generous loop (for later connection of the light) and continue to the next point until the last one.
Now you still need the light switch or motion sensor or dusk switch, wherever you want it. From there you run the cable to the distribution box (NYM is sufficient under certain conditions, but underground cable is better).
The corresponding wiring then takes place in the switch cabinet. Alternatively, you can also run the supply line for the lamps directly to the switch, motion sensor, or dusk switch.
Everything can already be completely pre-wired; only the connection to the circuit breaker should occur after all work is completed.

Carport:
For your carport (or the garage?), you should lay an underground cable NYY-J 5x2.5 mm², even better would be 4 mm², and terminate it in a sub-distribution.
That way, you can also install a “heavy current socket” (3-phase socket 16A) sometime later.

For your outdoor lighting of the house, carport:
Your idea to have it switchable from inside is already okay. You should consider a motion sensor; with the indoor switch, you can then either switch permanent light or motion sensor operation.
If you also want to switch your carport via this, you need, according to my suggestion, a second line to the carport.
Otherwise, just wiring with motion sensors and maybe a switch in the carport and connect everything to the sub-distribution.

If needed, I can gladly put together a wiring diagram with the required fuses, etc.

Very important: Always use a dedicated RCD for the outdoor area. Due to moisture, the probability that it trips is higher, and we don’t want the whole place to go dark immediately.
I hope this was somewhat understandable, it’s already late

Point 2:
A drawing would be helpful.
Otherwise, not too difficult a task.

Best regards and good night

Thank you very much

But what is NYM and motion detector? (I am a woman)

Motion detector = motion detector

NYM is the gray electrical installation cable usually used in houses.
The disadvantage of NYM, however, is that it cannot be laid everywhere without restrictions, e.g. in concrete (if then only in a protective conduit).

Just google NYM and look at pictures, then you’ll know what I mean.

Regarding point 2, I will come up with something during the day, a picture would be nice.

Here is our e-planning... Subject stairs

We will meet the electrician tomorrow for the first time... We are building turnkey, and we hope he is a good one

a little off-topic:

Do you happen to know the amount the electrical work is estimated at according to the standard construction service?
We had 2 quotes here, and they only wanted to credit us €2900 for the electrical work.
Although I come from the industry and therefore don't know the prices 100%, in my opinion no electrician can deliver a compliant installation for €2900.
