Why does this Mumbai house have 2°C lower temperature than the rest of city

Mumbai, often called the “City of Dreams,” is also infamous for its narrow, congested lanes and lack of open space. While most Mumbaikars accept these challenges as a part of city life, one man decided to redefine his reality by creating a stunning 25,000 sq. ft. luxury penthouse in Powai, right in the heart of the city.
Niranjan Hiranandani, a leading Indian real estate magnate, recently unveiled his sprawling 25,000-square-foot penthouse located in Powai. Hiranandani shared his penthouse during an interview with financial content creator Sharan Hegde. The footage showcases its breathtaking design and grandeur, presenting a remarkable example of luxury living that defies Mumbai’s space constraints and sets new standards of opulence.
Titled “You Won’t Believe What’s Inside Hiranandani’s 25,000 Sq Ft Luxury Penthouse,” the video has rapidly gained attention on YouTube. In the video, Hiranandani said that he always had trouble with the infrastructure of Mumbai and its congested lanes, thus he decided to create a self-sufficient township, complete with well-constructed roads, efficient drainage systems, and abundant greenery.

He said, “I lived in Lokhandwala Complex in Andheri. We built 11 buildings there. But the challenge was, when I looked out of the building, the roads were bad, the stormwater drain was not there. There were no street lights, there was no water supply or sewage lines, nothing. At the end of the day, I realised that one day, I want to make something where all the roads are built by me, everything was built by me. That’s why Powai was dreamt of. Everybody, including my family members, thought I was crazy.”
The penthouse of his city offers spectacular views of both Powai and Vihar lakes, a feature that is unique to Mumbai. Niranjan also mentions that his estate’s temperature is approximately 2°C lower than the rest of the city, which is possible due to the extensive greenery and thoughtful urban planning.

Being a financial content creator, Sharan Hegde, asked Niranjan whether to buy a house and how much should one spend ideally. The latter answered, “When you buy a house, it’s not just for living but also for securing your future and making an investment. I recommend that you invest in a house, regardless of its location—be it Bangalore, Mangalore, Mumbai, or elsewhere. The important thing is to consider it as your safety and security. Evaluate what you can afford in terms of EMIs, arrange for a down payment, and commit to a monthly payment plan for the house.”
He offers good investment advice, “…If the house is worth ₹1 crore, your annual income should be around ₹20 lakh. This approach provides a practical benchmark for affordability and long-term financial planning.”
