Usual size of this kind of pig pen is 8 meters by 4 meters which can accommodate 20 to 30 fattening pigs or 6 sow.

Take note of the shape of roof top and its simple ventilating system.  Even in hot sunshine the air can circulate and make the pig pen cool and dry.

For backyard hog raising, I made a pigpen 1/4 in size compared to my other pigpens.  It is 4 meters by 2 meters right next to the house. Still, it can accommodate 3 to 5 fattening pigs.
