Question about types of HDB Flats

OneWithTheForce SG

Can someone help explain the different categories of HDB flats : A, A(modified), NG, NG(modified), I, I(improved), S and STD flats.

I've looked at the HDB site and other property sites like propertyguru, but I cant find an answer to this.

I'd really appreciate any help with this. Thanks :D

Thanks noahnoah. Really appreciate it.

Do the letters correspond to the date of building completion at all?

Or do you have to look at each HDB block seperately to find how new or old it is?
