I have a small plot of land in Ka'u I'm wanting to toss a 16x24 shed roof cabin on. It's flatter than flat, a few inches of topsoil over untouched pahoehoe, in a small place well protected by trees.
While I want to build it as cost effective as possible, I see myself spending more and more time here and likely making it more permanent as time goes on.
Looking for input from people who have built similar things, or just know more than I do.
Considering the precast blocks with straps, 3 rows of 4 and making the girders/beams out of doubled up treated 2x8x12 intersecting over a post/footing.
Building the joists on top of that out of treated 2x8x16 at 24"oc with blocking if I can get away with it, or going with 16"oc if the 24 is not a good idea.
From there, 3/4" sheathing for the flooring, no internal load bearing walls. 2x4 at 16"oc for the external walls with the rafters being treated (is treated necessary here?) 2x8 at 24"oc (once again, willing to change that if I'm off the mark - 16ft span is pretty big though).
Front part of shed will be 12ft sloping down to 8ft in the rear... figure that'd be a decent enough pitch. So I'll have to build the front up and likely toss in some clearstory windows.
T1-11 siding all around nailed directly into the studs.
2ft (or more) overhand. But rain where I'm building it is nothing compared to Puna.
5/8" sheathing on top of the rafters, reflective barriar, and then 2x4 purlins before the metal roofing. Leaving the internal ceiling open beamed... no need for any additional weight up there.
This is what I am thinking, and feels cost effecting. Now I'm wandering where I may have gone wrong and what I might want to add a little more money into just to make it more structurally sound... or please tell me if I just went about this completely wrong.
I am wanting to do this below $6k if possible... but we all know how that goes.
