Alton Tatva Estates: My builder track record concerns

Honestly, I work in real estate, but buying for myself is a whole different ballgame. I'm checking out Alton Tatva Estates in Mohali. On paper, project sahi lag raha hai, but I know what builders don't always tell you about actual delivery and quality. Anyone here already invested or tracking it closely? Kya scene hai possession ka? Builder ka track record kaisa hai for meeting deadlines? Matlab, jo date bolte hain, uss pe milta hai ya kaafi delays hote hain? Off the record, I need honest opinions. Also, carpet area efficiency kaisi hai? Super area vs carpet area games toh common hain, but I need to know the real space and layout. Is it genuinely a good home ya just another investment play? Any red flags ya hidden issues with project delivery, ya after-possession problems?
