Thanks - it's good to hear that this stuff is of interest to somebody else ...
An explanation of what I'm up to ...
I have zero experience of bee-sheds - my hives having always been spread out far apart in the open air. And, although sites like https://www.honeyshop.co.uk/Bee.html are enthusiastic about the advantages of keeping bees in sheds, I still have a few concerns (in no particular order of importance):
a) just how convenient is accessing frames from the back of a hive, compared with opening boxes at their tops ?
b) airborn bees during inspections - just how much of a problem will this be ?
c) will the use of smoke during inspections cause problems (for me) ?
d) will the close proximity of so many colonies cause drifting of foragers ?
And so I'm hoping that experimenting with the Caravan/Camper will provide answers to at least some of these questions.
Judyv - thanks for flagging-up the ventilation & heat concerns. Although these had crossed my mind, I'd only been thinking in terms of Winter conditions rather than Summer, and so clearly need to give these a lot more thought - so thanks for the nudge - appreciated.
Even though the honeyshop article is somewhat limited regarding disadvantages, it does contain a graphic which I found very useful:
This being a picture of a Dutch open-fronted bee-house which, although more substantially built, uses the same basic principle as the wooden open stands which were used by Emile Warre in some of his apiaries:
But - although I've known of Warre's stands for some time, they've never really appealed to me - whereas that Dutch Bee-Shed (which likewise eliminates the airborn bee problem, the smoke problem AND removes the need to change from using standard 'top-access' boxes has (dunno why) ...
