Alternative Berm/underground Structure - Bent I-Beams | Construction and DIY projects | Forums

Just wanted to see if anyone else had come across a way to combine the wall and the roof of the house? KVR and speed both did beautiful jobs with the drystack and parge, and then a traditional stick roof attached on top, which in my mind provides a great opportunity for lighting on the northern side of the building. However, I was just trying to think of alternatives for economizing the construction and came across the idea of bent i-beams

Something like this but that would ideally go all the way to the ground so that you don't need a separate wall. You would still need concrete or a skin on top for insulation and waterproofing but in my mind it would be easier to have a green roof. 

Who knows, maybe it would be easier to insulate it if there was no bend at the corner. And of course you could have a green roof on both Speed and KVRs buildings, but this would be a "roll-on" where there's no step between the two.
