Have you seen hexagonal roving rooms?
It is rather uncommon but I've seen one in Batam, Indonesia. This is another I've seen in the swiftlet town Ban Laem. Err.. painted pink? That's unique! Hmm... a lady owner may be.
This is a large farm - probably 20m x 24m x 6 storeys! Multiple entry holes at split levels.
These are 3 farms in a row built by P'Jiap. His earlier design with open section behind the roving room on top is populated by pigeons (swiftlet friendly he reckons). He do away with that in newer farms now.
I'll update with more interesting & unusual designs here in future.
