GCE Road projects: Premium price, shady quality?

Golf Course Extension Road projects pe trust karna mushkil ho raha hai. Ek friend ne Sector 60 mein flat liya, possession ke baad itni problems – finishings, plumbing. Itna premium dekar bhi yeh sab? Kids moved out, I need a peaceful, manageable home. Kya aur log bhi same experience kar rahe hain? Any red flags?
