These video are uploaded by a resident of block A in Koi Kinrara. There is a scrap metal yard just beside it (facing Sunway view). You will not able to see this if you just wander along the pool area.

In fact, this property is completely surrounded by factories (left and right). Unless you don't mind the noisy sound, burning plastic smells at night. Then Koi Kinrara is a good place to be called home.
