Cob: RE: cob domes

cob domesBen,

Great idea!  I am also persuing a similar goal.  I, however, am using  a
metal frame, then a lathe/wire support covering, and then cob over that.
Rain is not a huge concern of mine due to the fact that I live in the
Chiuahuan desert, but I am sealing the whole thing with a layer of
lime/stucco plaster.

For resources concerning easy to build dome structures, I suggest you check
out the following links:
http://home.pacbell.net/bullnose/bluetarp.htm
http://www.desertdomes.com
http://www.colorado-research.com/~gourlay/dome/

Our dome home consists of a 3 ft by 3ft rock foundation, flagstone floors,
scavenged windows and homemade doors.  The home consists of 2 domes, one of
35 ft in diameter, the other 20 ft in diameter.  We have re-enforced
everything using rock walls for the door and window frames, as well as
making the cob much thinner at the top of the domes.

Good luck with you project, and let me know what you find!

Abe

  Subject: Cob: cob domes


  Hi cob people. I've never built a dwelling of any kind before. I've always
been interested in so
  called "primative" building techniques and types. I have a particular
fondness for dome structures.
  I've seen the Cal Earth site and bought one of their books on ceramic
architecture. I also own the
  book"Native American Architecture". I know most of the people on this list
seem to be concerned
  with the more traditional ways of building with cob but I am for whatever
reason obsessed with the
  notion of constructing a domical wooden frame (think wigwam or grass house
frame) or series of connected
  domical frames which I would then weave smaller skinny branches through
(wattle) and then cover this
  inside and out with cob or other earth type covering. I understand the
concern over rain in regard to the
  roof and all that but has anyone even tried this if only as an
experimental structure? I'm assuming some
  type of extra covering would be needed for the roof portion. Could such a
structure be fired or would the
  wood framework burn out and cause massive failure of the structure? I'm
thinking of such a structure
  for use as a cabin or as a small studio(I'm an artist), not as a permanent
dwelling necessarilly. Any thoughts?

  - Ben
