This is part 2 of this Build series on designing and building medium-density housing covers inter-tenancy floors. The most important consideration here is to eliminate penetrations into the inter-tenancy floor zone.
Just as the inter-tenancy wall (ITW) has special status in a medium-density housing (MDH) development, so too does the floor separating vertically adjoining units such as apartments. Due to the onerous fire and acoustic considerations between units, we chose in our book Medium to call this the inter-tenancy floor (ITF).
Firstly, the floor that separates two adjoining households is a legal boundary. This means that the ownership will move from fee simple – owning all the space above and below your piece of land – to unit title where ownership is defined by boundaries running both vertically and horizontally.
