Going to go off-topic a little, but this thread has made me think of an off-the-wall solution which I've never heard of anyone doing, but sounds eminently feasible...
Is there any law against having a feral colony or two in your roof? Very likely not.
Bees like living in house roofs. I'm a swarm collector for my area and in just the past two weeks I've had calls for three colonies living in roofs. It's high up (bees prefer being out of reach of predators), it's dry, and in winter it's warmer than being outside.
In some places, bee hives are enclosed in a shed, or in a trailer, so what difference if a hive is placed in a house loft?
Think of the advantages of having a hive in a loft - it would work for 'cold roof' constructions where the loft is cold, dry and ventilated.
No officials are going to notice, and if they do, it will appear to be a feral colony, not a managed one.
The bees will like it.
It'll make inspections easier - much less adverse affects from windy or wet weather.
It'd be best if a 'tunnel' was provided from the hive entrance to the eaves of the roof, could be easily done with a length of pipe and a connector each end to encourage the bees to only travel where you want them to. There will need to be an exit for bees that escape into the loft space when inspecting - most 'cold roof' constructions would be suitable with minimal changes needed.
There will be the advantages of much less problems with different types of weather, no problems from bears/livestock, children can't get near the hives, and if it affects you, small hive beetle lifecycle would also be impacted with the extra height between ground and hive.
The only disadvantage I can see is the possibility of bees in the loft being a nuisance in the house, so you may need to have a very bee-friendly family or have a fly screen arrangement in the access between the living area and the loft.
I would recommend having a few years experience though before trying this at home!
