I live in the South of Vietnam, Ho Chi Minh city. For the word you said, do you mean the condominium? It likes a building of a lot of apartments, right? If so, it is called "chung cư" here . If it is the combination of many buildings, it is called "khu chung cư".
Now, in Ho Chi Minh, khu chung cư Vinhomes Golden River is very popular. You can search this word by images and see if it is your word.
I hope it helps you.
