The demolition took place following a Supreme Court order in August last year, according to which, the nearly 100-metre-tall structures had come up in the premises of Emerald Court housing society in violation of building norms.

The towers were demolished using “controlled implosion”. Apex and Ceyane towers, both taller than the Qutub Minar, had 915 flats, 21 shops and two basements. Around 5,000 residents of the nearby societies of ATS Greens Village and Emerald Court had to evacuate their flats for the demolition.
