... Doughlass, farmhouses are not farms. The farm proper is the land being used for farming plus the agricultural structures. The farmhouse is really just a convenience - my family used to live in a farmhouse we were renting from the farmer, and his plan for after we moved out was to renovate the place and rent it out again!

'Prosaically' can be used to mean 'in a matter-of-fact way', so 'shrugged prosaically' does in fact have a useful meaning though it's not a word I'd choose.
