Well, if you've built it, then - sure - why not give it a try ?
In my view, for the back-garden beekeeper with just a couple of hives to be run in a 'minimum expenditure' and 'minimal-interference mode', the standard Warre Beehive can provide an ideal solution. And the bees adore living within that narrow 'chimney' space.
The problem - for me - was when trying to fit these hives into an existing (100% framed) working apiary, as the combs are totally non-interchangable between hives.
Your stack of Warre boxes reminds me of mine when I first built them ...
