The building material used in walls is of very poor quality. The bathroom wall could not hold geysers of 25 ltr as well. I am afraid to use the drilling machine, anywhere you drill you end up making big holes. The cement/sand falls from these holes like powder(No adhesiveness). The door of rooms and washrooms is of cheapest quality possible. its chipping off like anything. Spend 4k more on every door to if you want it to be worth looking at.
