Hi, Thanks for your detailed reply. Just a quick check, for facing direction of a HDB flat, which is more crucial, the direction of the main living room window and door or the location of the Kitchen, Master bedroom, etc...? The reason i'm asking is that i'm choosing a flat soon and i'm not too sure which aspect is more critical as it will influence the decision to choose the flat. Also, to verify the direction of the place (for ex. kitchen or master bedroom) in the flat, we should take reference from the center of the flat using a compass right?
