E-11, located in the heart of the city, is dotted with unauthorised high-rise buildings and several illegal cooperative housing schemes. However, no serious action was taken against them by the Capital Development Authority (CDA) and district administration, which deal with such housing schemes.
On the other hand, housing schemes and other owners have narrowed down nullahs that cross through the sector. The street where the affected house is located has been built on a nullah.
During a visit to the area, it was noted that seemingly the incident took place due to heavy rain (103mm) and existence of narrow nullahs.
