According to https://www.scdf.gov.sg/content/scdf_internet/en/building-professionals/cd-shelter/permitted-works-for-household.html, "Closing or covering up of ventilation openings by removable aesthetic or architectural finishes is allowed, provided that at least 25% of the total area of the two openings shall be left uncovered for ventilation purposes during peacetime." So has anybody here done anything to any ventilation openings of your household shelter?
As we know, our household shelter has two ventilation openings - close and open position. In my flat, if i am not wrong, open position is facing living room while close position faces kitchen. If I plan to install wall cabinet in living room, am I permitted to switch positions?
