ᐅ Outdoor Electrical Installations – Have You Considered Everything?

Hello everyone,
This week we’re starting on the outdoor area, and before laying extensive paving, I want to coordinate with the landscaper to install the electrical wiring.
Current situation: From the utility room in the basement, there is a large empty conduit for electrical wiring for the outdoor area. Currently, the following run through it:
- 1x 5x10 cable for the wallbox charger -> will be located at the carport
- 1x 5x2.5 cable for a future sauna -> runs from the carport further into the garden
- 2x power cables for the carport (5x1.5)
- 1x network cable (RJ45) -> for the wallbox and anything else requiring network connection
Everything is connected to a separate residual current device (RCD) in the electrical cabinet. At the carport, all cables currently come out of the ground, properly sealed against moisture. Here I have my first question: How do you professionally bring these cables up from the ground once the area is paved? An outdoor floor box? What do I do with cables like the sauna line that continue further into the garden? I was simply planning to continue them in a separate empty conduit into the garden.
Since it was already quite difficult to pull these cables through the empty conduit to the outside, I would prefer not to add more cables there.
My idea is to install a small sub-distribution board in the carport (there will be a garden shed at the back) and run additional lines from there to supply the other devices.
This would include:
- Another 5x2.5 cable into the garden for a possible pool and anything else like a pump, etc.
- 3x1.5 cables towards the cistern (also in the garden)
- 3x1.5 cables in front of the house under the paving heading to the inspection chamber (for a backflow valve)
- 3x1.5 cables in front of the house towards the street for a potential future doorbell at the garden gate (not planned yet but who knows)
- 3x1.5 cables into the garden for garden lighting
Since the garden won’t be done at this stage, it’s important to lay the cables under the paving now so that they emerge near our soil mound.
Are there any other important points I should consider, or have I covered everything?
Best regards

Since I wasn’t sure what I might need later in the garden, I used "Rechtsanwältin Bird JMB-H Ventilbox" distribution boxes around the house and connected them with 1-2 Kabuflex conduit pipes. Two KG-110 conduits run directly under the control cabinet into the utility room. This way, I can easily and flexibly pull cables from the utility room wherever needed. Only the final cable installation still needs to be done, but without having to dig up the entire garden.
