I just wonder what the intention was of including that diagram in the book if not to save on labor and wood, while maintaining a thick insulative natural wall.
Um, no the bank nor the city will allow me to do the build though that would be my preference..I have not built in a seismic zone. I'm not a PE though I have a degree in ME. The design is far from being finalized.
I do have some sketchup models I've been playing with and I'd be happy to share if you're really interested.
In one I had a timber frame of 8x8 and then I added a WTS with 24in spacing and it just looked like so much excessive lumber. So then I thought well if all this 2x is necessary can we ditch the timber frame?
So I modeled a version with only WTS of 2x4 (on both sides) 24in oc and it still looked like a tremendous amount of lumber. So I've been stalling and ruminating and came across that diagram and thought, eureka! but I couldn't figure out the forming so I posted up here.
Regarding extra engineering for seismic concerns. The city's policy is the building should meet 2010 IBC.
...I don't think there are extra measures that need to be taken for seismic issues, legally speaking, though robust design and deep pockets might want to play it safer. I don't want my house to collapse on me, but I also have this tight budget and a feeling like this apartment is a cage that is slowly killing me and having to finance land, design, plan, permit and build more or less all at once. So as in most cases its a delicate balance of wanting something badly but trying to not stress out about it too much.
My specific question is whats up with that diagram in the textbook showing a light straw wall with 2x6 framing on only one side of the wall? how do you form for that?
I understand you're interested in building well, but if the owner can't afford it then what? Why is it so hard to acknowledge that people have constraints in their budgets and lives?
I mean in terms of literally stacking functions it makes sense to use roof space as living space, though structurally I can see how it might be a challenge.
I'm sure its due to the materials used, but I find it interesting given what you said, Jay about flat roofs, that nearly every commercial building I see has a flat roof. I also see houses with flat roofs all around but maybe they're just failures waiting to happen, or their owners were able to invest in some effective but probably unsustainable material.
Our target price per sq ft is around $150, this is just pushing our limits. The land will probably be around 220k ish (for 3+ acres) hopefully we can get them down to 200k which then would leave us with about 150k to do the rest from bare land. The house design is staying around 750-800 sq ft.
