Lighting and electrical planning in new construction

The router will probably go to the office (upper floor), so I guess I’ll need an access point on the ground floor and on the terrace. Right?

Am I correct in understanding that you are planning almost 150 sockets for just over 200 m² of net living space? What do you intend to plug in all there?

A lot has already been said about the ceiling spots. They are a matter of taste. I would prefer ceiling lights and wall or floor lamps.

we looked at the spots, the light, and the shadows before making a decision.
The result was that the spots were too small and had light with harsh shadows.
Our choice fell on LED panel lights, dimmable, adjustable 3000-6000K, and lights with E27 sockets,
pleasant light, no glare, no shadows

What is the reason that the router should go to the office? Your network cabling will converge at one point, and I would put the router there. What kind of connection will you get? Fiber optic?

What did you have in mind for the access point? Ceiling mounting or wall mounting? I prefer ceiling mounting. Then the units should support POE and you don't need a power outlet at the access point.
