The majority of the the space in our house extends up the the “shell” of our structure giving us glorious twelve foot ceilings.  The exceptions are in the two bathrooms and closets.  We wanted to have an “normal” ceiling height in these spaces.But more importantly, we wanted to create storage space.And in the case of the space above the master bath, this is where we will put the ventilation system for the house.   So that makes this our usable attic space where in reality, the true attic space of this structure is filled with hundreds of tons of earth.
