Hello Joyce- to answer you questions, yes those are corrugated silos, one at the
center of
the building at ten feet diamter (it's my bathroom, with a 16' ceiling) the roof
trusses
radiate outward from its edge and catch the perimeter wall at 15 feet of span,
for a 40'
diameter building. The second silo is at the edge of the perimeter wall, and I'm
using it as
an entryway to keep the internal and external temperatures of the structure away
from
each other- also some times of year its extremely windy here and having an entry
way
helps with keeping the wind outside when you open the door.

As for your burlap question: yes, its real burlap bought from the garden supply
store, for
about $3.40 for a seven foot square piece of it, which 49 square feet. My
exterior walls are
1,200 square feet, so one layer of burlap would equal 24 and a half pieces.
That's $83.30
in burlap to cover the walls once, but since I'm overlapping them about halfway,
let's
double that figure and call it $167. The Cement-All costs about $18 per 55 lb.
sack, and
covers about 25 square feet when you account for the dual layer of burlap. So it
would
take 48 sacks of Cement-All non shrinking, rapid set grout to finish the walls,
which will
cost me $864. Of course it won't be quite that much, as I do have doors and
windows
which would need to be subtracted from the square footage. About a thousand
dollars.
That doesn't take into account the wire, the metal studs (if I did it again I'd
use rebar
because its cheaper and I'd make a dome and use this burlap-crete as the roof as
well-
probably three or four layers thick overhead where it would potentially be
walked on.), or
my labor.
