Think about flight path, if you can get this away from the main part of the garden and can force the bees high (2m fine plastic mesh does the trick, put a water source on the bees side of the mesh as well) then you will hopefully have a happy coexistence! Just remember that it'll be best to have the garden to yourself during inspections though. I agree with Midland Beek, you'll want multiple hives for 'critical mass' and contingency but you are well placed for that with your choice of hive since a beehaus is two hives in one is it not, so ready made expansion? Wld suggest you put expansion to two viable colonies by autumn as a higher priority than a honey crop.
