common practice - most people would have one side of the ventilation holes covered and the other in it's original state. if possible, home owners usually construct a fake wall to hid their storeroom from sight.
since my design doesnt allow me to hid it from view, i'm only allowed to cover up 1 side and left the other side in it's original state.
but over the weekend, i finally removed the SUPER UGLY, EYE SORE ventilation cover from the storeroom.
and replaced with this. cost SGD25, bought from Block 31 Kelantan Lane.
isnt this much nicer? slimmer? no screws nor drilling required. i stick it up with some bluetack.
as for the original metal plate...it's chuck somewhere inside the storeroom. remember to place it back before you call for a flat valuation in future.
