What future-proofing should I include when refurbishing an apartment?
Although all those things are good, and in fact I always do the first three on your list, the important thing is not actually installing them, but ensuring you run cable ducts.

If you have ducting, then you future proof the apartment - need another cable? just run it through.

So plan as follows:


Decide where you will need Ethernet, power and audio wall plates
Plan your server closet
Identify ducting size to cope with the planned cables plus more as yet unknown ones
Ensure ducts for power cabling are as far away from signal/low voltage cabling ducts as possible
Install cable ducts to all those points
Also install cable ducts to useful positions on walls in other rooms


I typically also leave a pull-wire in each duct just to make life easier if I do need to add something.
