Slight thread resurrection – we’ve now moved into our new place, which consists of a main house and a detached annex, the annex is about 20 feet away from the main house, across a stone-cobbled yard. There’s no option of getting an ethernet line across there that doesn’t involve lifting those cobbles, and that ain’t happening.
However, it looks like the previous owners gave some thought to this, as they’ve got one of these on the back wall of the main house, facing the annex:

I assume they set it up as an AP to provide WiFi to the annex, as there’s just the one unit. The cabling (ethernet and power) runs back into the main house to a controller/power unit where the main router lives. Well, will live, we don’t actually have broadband yet, it should get turned on tomorrow, and when it does it’ll be something like 7mb (for now, we might look at 4G/satellite/other options if needs be).
So, I assume that, as an AP, that unit is pretty ‘beefy’, and should easily handle providing WiFi to a separate building twenty feet away? The other option is to get a matching one facing it across the yard, setting them us a point-to-point link, and wiring the second unit into a separate router in the annex, but I think that’s probably overkill?
