This dev has been developing bandar damai perdana for decades already. No worry about abandonship, just quality is the discussion based on earlier phases.
TS can go to the said taman and have a look. Their sales gallery is always there. Suggest TS just walk in to ask more questions abt this project.

One can register cia the link.

But the content has explicitly spelt
"The Courtyard @ Bandar Damai Perdana, Cheras"

This site MUST be an empty land of BDP, can't run away.

What l did in the past was just walked in to their sales gallery and asked. They would give the details as they could(despite not launched) and left my contact number there.

Later take a tour at BDP and see if this place is suitable for you and your family.
