Infrastructure changes really shifted Premium Builders' market dynamics.

I'm upgrading to a 3BHK for my family; kids ke school admissions are a priority. Prices around the Premium Builders corridor have jumped. Is this mainly due to new connectivity like Dwarka Expressway ya metro extensions? Which specific pockets gained most? My wife wants a safe, established neighbourhood with good schools nearby. Should I consider areas still developing, ya established ones are better for family living?
