wow! Need so long to approve by HDB! Tot apply permits all in one shot, HDB will approve all in one shot too! That's why I tell myself that when I am doing my reno, I want my contractor to apply before renovation starts so when I get my keys, all permits will approve and can start hacking. Hmm... seems like I need to pre-warn my contractor about the hacking walls part.. Think apply 1 month before reno start to play safe wor!
