After reading on the details and going on a virtual trip to the Kowloon Walled City I have a big change of perception on how cities could be built if architects don't exist. This is certainly a mind-blowing structure of the city. It consist 14 stories for each apartment and having the city in the lenght of 126cm and width of  213cm . After having a preview of Kowloon City I have realized how important the knowledge of built enviroment is . First and foremost, the city had zero penetration of sunlight which is one of the major need to live a healthy life. Plus, when there is no sunlight penetration then the place will have zero plants and trees which reduces the oxygen level of the place. This has caused many people grow ill in a very early age. Secondly, the fact that the shops are all mostly placed at the ground floor till the 5th floor , it has no light which instantly lacks in sanitization. This can cause many diseases spread around in a flick second. Thirdly, all the rooftops which is the major place where light can come is fully covered with rubbish which clearly gives a very bad aroma and air circulation, and this could have been solved if there was proper disposal area made. Next, if I looked in safety, this is place is no place to be out in the midnight because being dark you never know what can happen when and not having clear pathways and roads can make the elderly people fall down or lose stability and small kids can get hurt or lost because of the uneven and unorganized pathways. Moreover, living a positive life is a  very minimal chance in Kowloon because since there is no law to abid, criminal doings is at it's highest rate especially drug dealings, this has caused massive people in addiction which leads to even more issues carried on in the family and to the society. In conclusion , not abiding to the building law can really bring a city to chaos because not having a systematic structure can really bring some massive problems to the living and life of the people. This is something most of us are unaware of and i think i learned some valuable learnings from this virtual trip to Kowloon Walled City.
