earthquake-prone areas.
The A-Pame structure gives
a concentrated low gravity
base with minimum over-.head
and wall weight. The outside
is reinforced steel
with a continuous urbroken
line of seams running
parallel approximately six
inches apart Porn the base

apogee and returning d.ownward
to the other side of
the concrete base. A small
window on the "second floor"
offers adjustable ventilation.
The width of t:he
