Moving from entitlement to pre-design and even schematic we still use floor as unit/group without walls and entry. At this point in time an entry usually needed to drive circulation, egress, etc. yet the unit still changing, and 65% chance it will. Our people spent time adding the unit walls and add that entry, and very often turn out the unit will no longer be used.
I wonder what others use in multifamily project to add an entry into the group (assuming they use floor) without laboring adding the walls.
