this is kampung deret petogogan.
i used to pass this area on daily basis on my way from this office. sometimes the traffic jam made me stop and i could look around while driving. it was a slum. a terrible one. then the office was moved to other part of jakarta. and i almost never pass this area anymore.
but a few years later, i was surprised. the slum disappeared and turned into this orange-grey row of buildings. it was so beautiful and clean so i had to stop and took picture.
