What's driving the surge in real estate projects in Chandigarh, Mohali, and Zirakpur?

I've noticed a significant increase in commercial and residential real estate projects across Chandigarh, Mohali, and Zirakpur. However, it seems like the IT sector in the region hasn't grown significantly, and I don't see a substantial influx of people moving to the city. Developers are investing hundreds of crores in these projects, which makes me wonder—do they know something we don’t? Is there any news or upcoming developments in the Tricity area that might justify this surge in real estate activity? Would appreciate insights from those familiar with the region or the real estate market. Does this align with your intent?
