Others who were present in the building escaped unhurt but Rajesh Gupta (60) and Uma Gupta (55) were killed in the wall collapse, they said.
The incident occurred around 6.35 AM and seven fire tenders were rushed to the spot, an official from Delhi Fire Services said.
The couple had been living in the area for the last 30 years along with their children, Karan and Isha. They were also present in the house when the incident occurred and had a narrow escape.
Uma and Rajesh were rushed to LNJP Hospital but they were declared brought dead.
The fire officials had a tough time cleaning debris since the lanes leading to the house were narrow.
