Inspecting a 3 storey Swiftlet farm in the North. The concrete structures are almost completed now only left the top floor.
Here is the control room and in future the workers may to stay here .
This is the inter hole. Big enough for the birds to fly up and down. You want a good Bh? Must be generous in term of space allocation. 
Double layered red bricks for security and good insulating.
Perfectly filled with cement between all gaps of bricks. Many never pay attention to this. This is the different between a good and a poor swiftlet farm
The concrete beam must be thick and huge enough to support the load of double layer bricks. How many of you had though of this or just leave this responsibility to the contractor.
I only use red bricks. Do or done. If you can't afford red bricks then you shouldn't get involve in it.Enjoy the pictures.
Good Swiftlet farming All!
