Hyderabad is not Mumbai - why so many highrise apartments?

Mumbai is a city which is geographically restricted and there is a scarce availability of land. Hence, there is only space to grow vertically into the sky. In Hyderabad that is simply not the case. Then why would you have so many of these propping up suddenly -> Lanco Hills, Lodha Bellezza, Aparna Sarovar, Aliens Space Station, etc.

The recent fire episode in Bangalore was a wake up call for people who live in High-rise apartments. High-rise structures pose particular design challenges for structural and geotechnical engineers, particularly if situated in a seismically active region or if the underlying soils have geotechnical risk factors such as high compressibility or bay mud. They also pose serious challenges to firefighters during emergencies in high-rise structures. New and old building design, building systems like the building standpipe system, HVAC systems (Heating, Ventilation and Air conditioning), fire sprinkler system and other things like stairwell and elevator evacuations pose significant problems.

Some of these High-rises have helipads on top of them so that people can be evacuated using helicopters in the event of an emergency. How fast can the fire department or the police arrange for helicopters that can evacuate hundreds of people from the rooftop? No prize for guessing this question!

The International Conference on Fire Safety in High-Rise Buildings defined a high-rise as "any structure where the height can have a serious impact on evacuation".
