My question involves the footer. What I'm thinking of at this point is to
have post holes drilled around the perimeter at every 4' at about 18" or 2'
depth. Then slam some rebar down in there, along with 6" diameter or so
steel pipe which will extend 2' above ground level. Will fill the holes and
pipe with concrete for a good base, and lay 4X4's across the top of the
piping ( or maybe 2x6 with 4x4 on top) to function as the base for the
walls. Wall frames to be bolted to this base

Does this sound reasonable? Will place concrete blocks between the pipes to
fill-in the space, with a stone facing on the exterior.

Does this sound like it will be strong enough to support the GH, as well as
keep the GH anchored to the ground during windy periods? It will be
sheltered on three sides by my home and sizable trees to reduce wind issues.
The exposed side will be the south.


I don't doubt that it would be strong enough (actually it sounds like
substantial overkill), but check with your local building department (if
you have one). My township insisted on some pretty unreasonable
requirements for my greenhouse. It is best to ask first rather than
make expensive alterations. Make sure the footings are below frost
level (assuming you get frosts), or they will heave right out of the
ground. Here we have to dig to 4 feet deep.
