Martin,
Thanks for your response.

Good thought - I will give wifi a try first.

I’m a bit concerned that the wifi signal will be shielded by the foil on the Celotex insulation that will be in the walls, ceiling and floor.

Am I worrying unnecessesarily?

Provided there is a window facing about the right direction I expect the
Wifi signal will get in fine. If all else fails I have run Wifi over
distance using a simple £8 USB Wifi with detachable aerial and an
external high gain antenna. That takes a bit of setting up but has the
big advantage of no risk of lightning ground emf destroying kit.

My first (expensive) Boca dialup modem was killed by a lightning strike.

Quick way to find out is to test it with a portable and a Wifi survey.
