Ya...pre-fab has different type. The most ultimate one is the latest at Punggol HDB. Even the window frame is pre-fab into the wall and assembled at site. NV, Livia series of pre-fab is not uncommon. E.g. Woodsville 28 is of almost the same type. 1 planter box at living room, curve window with 1 pillar at the corner. LOL.Originally Posted by 3C
