One thing I would say is, do you currently have any devices, physically connected to the VM hub in its current location using an Ethernet cable? As you mention TV, I assume that you have VM’s TV provision as well as broadband, however unless you have one of the older TiVo boxes, these need an internet connection of their own via the hub. Now this can be via WiFi or a physical Ethernet cable linking the TV box to the hub (which is more reliable). If the hub is moved somewhere else, then VM’s techs won’t run any Ethernet between them, that’s down to you, you’ll have to rely on a WiFi connection. If you currently use WiFi anyway, then there is a chance that the further distance will make the connection problematic.
Without knowing all the details of your current setup and house plan, it’s impossible for anyone here to give any sort of guarantees or outright ‘no that won’t work’. There’s a reasonable chance that it will all be OK, but something to be aware of beforehand.
