I just put the finishing touches on the 8×20 solar house and uploaded the plans. I can see how SketchUp Pro with the bundled presentation building software, Google Layout, would be a real time saver and would really improve the final output. But I’m still amazed at the high quality 2D and 3D renderings that are possible with the free version of SketchUp. I’ve posted the first version of the plans for the 8×20 online for your review. I’ll take the feedback posted in the comments and try to do a quick revision.
I know I’ve missed some important things like specifications for hardware and lumber in the plans. I’ve been thinking that 2×4 framing, 24″ O.C. and 1/2″ plywood or OSB for the sheathing. Anyway take a look at the plans SketchUp file and let me know what you think.
