It's remarkably simple to make too. I could build the whole thing in an afternoon, as long as the glass is cut with no sharp edges.
The lower base is just skirting board and 20mm ply and stays still, the swivel part is just the same but with 4 trolley type wheels to help it swivel the entrance pipe is just press fit and swivels easily. I'm going to make some adaptions to it , add a mesh floor for improved ventilation( although double glazed on 2 sides it's basically going to be room temp) but also so I can vape the bees without opening them. They need cleaning once a year which will be a case of transfer to another hive.
3 possible locations are a local school, uni labs at the botanical gardens or the cafe of a water garden nursery where some of my bees are. I won't stock it til spring as I'd rather know where I am with the colony that goes into it, rather than trying to figure out whether it was the bees, the hive or something else that caused problems if they occur.
I may have built another couple by then.
