Many houses down here use a totally different approach to lower walls, Many use what are called 'break-away' walls on the ground floor. This is a ' what else ya got, bring it on ' wall....if this wall goes, we all have big trouble. This wall is heavier that most condominium walls. The AC & generator support shelf will go on this corner of the house, just above where you see the green thing in the above right photo. We may try to build a DAC-ART chase wall to provide protection for the AC unit and the generator. It is not uncommon for hurricanes to blow away air conditioning units, generators, electrical boxes or anything left exposed.
