[Cob] about greenhouses...

[Amanda Peck]

I wrote a nice little message, and then hotmail ate it!

It sounds doable.  If I were doing it myself, I'd ask someone who presumably 
knows about rubble trench foundations, if that will impact on the house's 
foundation--or whatever it has.  Also about tying it to the house at the 
top.  I expect you'll need a plate all the way around, but I don't know 
about flashing to the house, and overhangs from the house.

and DRAINAGE DRAINAGE DRAINAGE.

Drain to daylight from the bottom of the rubble trench.  Kep water off of 
both the greenhouse AND the existing structure.  Keep water off of cob walls

If I were doing most of the work myself, I'd seriously consider putting up 
the roof first--or after the foundation anyway.

May not need much in the way of clear on the top. (some friends have a 
little all-clear add-on greenhouse, complete with water barrels for heat 
storage.  In winter they open a hole into the house that has a fan in it, 
thermostatically switched to warm the house when it gets to 80 in the 
greenhouse.  It's on a LOT.  In summer they put up shade-cloth and open a 
large handful of vents.

I've never built with cob before and I am interested
in attaching a cob greenhouse to the side of a (gasp!)
manufactured home. My idea for the greenhouse is a
simple cob framework and floor enclosing large pieces
of unframed glass. Does anyone have any suggestions
for me? Any advice would be great.
