Sohna site visits hide future construction issues

Sohna — thinking about upgrading to a 3BHK or a small villa here, but I'm a bit confused. Currently in a 2BHK in Sector 57, it's getting cramped. Signature Global City 93 jaise projects dekh raha hoon, under-construction hain. Builder ka track record theek lagta hai, but site visit pe actual construction quality kaise judge karein? Kya dekhe walls, columns mein abhi? Log bolte hain baad mein cracks ya seepage aati hai, woh abhi kaise pata chalega? Kids play area aur clubhouse ki future quality ka idea kaise lagayein? Koi tips dega site visit ke liye? Already home loan chal raha hai, so I don't want to regret this big jump. Is it worth the premium?
