[papercreters] Pole Barn / workshop project

Howdy, been a long time since I posted regular, although I read and catch up on everything periodically. Evelyn prompted this discussion, as I have a new project coming up that was of interest to her, but I am open to comments and critiques from all.

I am having a pole barn / workshop built in my back yard. It is going to be a 24 foot square. It will not be enclosed or have floors to start out, just 8 poles, in this configuration:

Not sure that will come across well, but 3 poles on each side of the structure (to support scissor trusses at a 6/12 pitch), one on the back side and middle centered between the outer poles. The original design only requires 6 poles (clear span on 6x6 posts). The two additional poles will be sunk load bearing just as the other 6 and I will eventually use them for floor support, a loft and a chain lift.

The papercrete portion of the plan thus far consists of enclosing the workshop on all side with PC for insulation and to support openings (3-4 windows, 2 36" doors and a rollup door). It will also be used as insulation for the galvanized roof.

Ideas so far are:

1. Put a 4" or so deep concrete footer around the outside of the poles, stack a course of concrete block on top of that and then use that as the base of the wall.

2. Pour sheets (perhaps 4'x4' and 6" thick) to use as insulating panels under the galvanized roof.

I like going outside the structure for a few reasons. First it gives max inside space. Second I can string runners between the poles and put screws through the PC to the posts and runners to secure it.

A few notes about my location. I am in Central Florida, which gets a decent bit of rain but also has excellent drainage (in my area at least). Heat is more of a problem than cold, so I am looking for ways of getting light in while limiting heat. I hear solar tubes works fairly well, and wonder if anyone has surrounded one with PC before? I am also open to ideas on resources to read or just ideas on influencing air flow since I doubt the structure will have air conditioning for several years if ever.

I am sure I have missed something, but that is more than enough for the first post. Fire away.
