'Trying to get this done before it gets to be Winter.
...but wait a minute...
that's what i said last Fall!

Since then, 'got the hole dug, a slab poored,
and a couple tiers of cinderblocks set as a partial stem wall.
Then did 2x4 framing on a 2x8 plate, with the 2x4s offset /alternating
interior / exterior on 1' centers, to limit thermal conduction via the studs.
'Scrounged enough 12" TJIs for the entire roof, from the Resource yard.
Most of the 2x lumber was recycled, as well as the windows & door.

On the north side, the bottom of the wall cavity was first filled with earth
to a depth of up to ~2', as that mass will help provide thermal modulation in the coop
Used treated plywood & a plastic liner below grade, though i wouldn't
expect moisture issues with generous eaves on the north side. 'Metal roof is on,
and i'm getting ready to apply stucco.

It's all for you guys... The excavation & terrace, taking shape Radiant tubing laid with wire mesh both under & over You don't see here, the tubing going out to the "duck pond" The slab The framing The skin is mostly on Stuffing the walls with straw Close-up of typical wall cavity, with offset 2x4s Filling the roof cavity with straw Standing seam metal roof is on, as well as gutter just in time for rain... still need to trim north edge Doorway, with paper & stucco lathe up Roostin'

Still to do, is the exterior stucco, the attached run,
the duck pond, and the active solar-heating system.
