Many people are confused about building a Swallow house because they do not have a building design that fits the pocket. If you have the same constraints, let's learn to make a minimalist Swallow house design with capital that is not too large.
One of the Swallow building designs that many Walet farmers like is the design of the Swallow house model zigzag. This house can be used in all sizes, including 4 x 8, 5 x10 and 5 x 12.
The difference is that in the interior or part of the Swallow house there is a VOID (plunge hole) in the shape of a zigzag. That is, the hole that became the bird's flyway Swallow between floors made zigzag, not straight from bottom to top
