Hi everyone,
things are starting to get serious for us. It’s time to think about the basic locations and quantities of power outlets, light fixtures, network connections, satellite connections, and conduit pipes.
I’ve roughly sketched and attached my current planning status. Maybe someone has helpful feedback for me? Does anyone see a spot where I definitely need a network connection, conduit, or something similar?
To explain:
· We’re also installing a controlled mechanical ventilation system, which will be embedded in the screed of the basement ceiling and the ground floor ceiling. Because of this, we can’t lay conduits inside the screed insulation, as that would interfere with the ventilation’s oval ducts. I’m also generally not a fan of conduits with bends and curves. Therefore, my plan is to run conduits vertically down the walls to the basement whenever possible and then gather the cables there in cable trays.
· The current plan shows a full installation of satellite connections and network outlets. All of these will be laid in conduits that will only be filled “when needed.” Child 1 is currently 16 months old, and Child 2 is still in planning. So it will be at least 10 years before satellite or network connections are needed in the children’s rooms. By then, there will probably be entirely different technologies.
· The recessed ceiling spots will be cast into the precast concrete ceiling, so there will be no suspended ceiling.
· The various conduits on the ground floor will simply run straight down to the basement. From there, I can route the cables openly below the ceiling to the switch, satellite system, or 5.1 receiver (which will be located under the TV in the living room).
· Likewise, the cables for network and satellite from the guest room, living room, and bedroom will be laid in conduits running straight down. The endpoint is again at the basement ceiling exit. From there, cable routing will be either open or in cable trays.
· In the office on the upper floor, there is a small tech shaft that runs down through the pantry on the ground floor into the technical/laundry basement. The cables for the office and Child 1’s room will run through this shaft.
· Child 2’s room is still a bit of a concern. The room is completely cantilevered over the living room, so there is no wall underneath where I could run a conduit down. I would have to somehow work through the dressing room. In the worst case, I’d route the cables openly in the dressing room and then together with the bedroom cables down to the basement.
· In general, I am only having conduits and empty boxes prepared inside the walls; I will install the network and satellite system myself.
Thanks and best regards,
Andreas

To those who have installed empty conduits:
What type and diameter did you use? We have a prefab house with pre-clad walls and empty conduits running down to the floor. They installed deep electrical boxes, but only 20mm (about 3/4 inch) conduits—although at least the high-quality ones with membranes. 25mm (about 1 inch) conduits don’t fit very well into the airtight boxes, so that’s understandable.
For that reason, we mostly continued with the 20mm conduits to ensure a proper connection, but where it made sense, we also used 25mm, 40mm (about 1.5 inch), and 50mm (about 2 inch) conduits for larger cable trays, for example between the basement and the utility room. Through the 50mm conduits, you can pull 10-12 NYM cables or up to 15 CAT cables.
What’s really unpleasant is pulling cables through already fixed conduits, so it’s best to cut the conduits first, fill them with cables, then install them—that works best. Otherwise, use lubricant, insulating tape, a cable pulling aid if necessary, and above all: prepare well.
For example, to get 3 NYM 3-core and 6 NYM 5-core cables into one 50mm conduit, I sorted the cables for about half an hour and tied them into a bundle so they don’t cross. Anyone who takes that effort will be rewarded by easily pushing the bundle through the conduit.
One more thing about the recessed lights: I think the ones in the kitchen probably won’t work very well, judging by the layout. Is the oven located on the right exterior wall at the bottom? If so, the spotlight will likely cast shadows on your roast when you take it out, and the same applies to the other lights except the one above the sink. If you are going to have spotlights, they should be placed directly above the work surfaces for them to be effective.
We also installed spotlights in the kitchen and hallway in an open wooden beam ceiling, and with careful positioning, shadows can be almost completely eliminated. However, you will need quite a few of them.
Proverb WLAN: With today’s new construction floor slabs, no WLAN signal passes through anymore. Directly above our utility room, there is no signal at all from the current FritzBox in the bathroom (no WLAN network is found). It is strongly recommended to plan for an access point on every floor (or at least a LAN connection to later connect your own access point to the LAN port).
If you use satellite, double sockets generally make sense almost everywhere (simply because each receiver gets its own connection), and then 12 sockets are not that many. We only installed 5 DVB-C (cable) sockets and 0 satellite sockets.

I don’t understand your reasoning regarding the double boxes.

@Uwe82 Ah, a prefabricated house—that explains why the electrical cables are installed in conduits. We are building solid construction (I probably should have mentioned that, sorry) with Poroton blocks and concrete ceilings.
Only the SAT and network cables will go into the conduits; electrical wiring will be installed traditionally under the plaster.
The note about the conduits needing to fit the sockets is already helpful, thanks, I hadn’t considered that!
@Payday
Yes, you’re right, we already have that problem in our current house, and it won’t get any better with a 22cm (9 inch) concrete ceiling heavily reinforced with steel in the new build. A Fritzbox won’t help you much there. Changing the country setting to China doesn’t really make a difference either...

I understood the part about the stairs, but one spotlight in the ceiling of the stairwell is definitely not enough. We have 3x 20W lights over the stairs and 3x 20W in the upper hallway. The basic lighting (stairs, bathroom) (8x 1W) is on from 6 PM until 7 AM, so I don’t have to turn on bright lights at night when I need to use the restroom, and the stair lights are only switched on when you need a lot of light.
We used 25mm (1 inch) conduits for CAT7 duplex cables, but pulled the cables through immediately.
P.S. I would install the network outlets correctly in the kids’ rooms right away; otherwise, you will regret it later.
Our bathroom is also T-shaped. What do you want with a 2m (6.5 feet) long shower? You still use a glass door for the shower. We have a 1.6m (5.3 feet) shower and 1.6m (5.3 feet) for the toilet—no one sees me. For the bathroom, I recommend two exhaust vents: one in the main room and one over the toilet.
