Are Dreamkey Infra's hidden charges normal?

Vasant Kunj Enclave – I'm looking at a 3BHK with Dreamkey Infra, quoted around ₹2.2 Cr. Honestly, I work in real estate, but buying for myself is different, these hidden charges are driving me crazy. They quote one price, then suddenly there's PLC, parking, and a whole list of possession charges beyond just stamp duty and registration. Is it standard for builders to spring these *after* initial talks? How much can you actually negotiate on these 'extra' costs? Feeling like I'm constantly being played.
