In spirit of novel A-frame-ish designs, my plan for the first serious build has been a green roofed A-frame ever since this video I saw last May
Well it's a flat topped A frame anyways.
About the same frame as is filmed, except probably a bunch of on site milled siding instead of paneling, and the roof will be green.
The only significant deviations from "traditional" lined green roofs I think, will be throwing down dollars for stainless steel flashing, sourcing quite a few loads of halfway rotten scrap dimensional lumber of 1.5" thickness to lay up and down the whole length of the roof, and then transplanting some of the horrible, the terrible, the awful, English Ivy along the sides of the house, where I will have made a fancy fertilized irrigated planting bed for them to make that whole thing a living surface in 4 or 5 years instead of 20.
Once mature, the scrap dimensional lumber and English Ivy will have made a sturdy few inches of soil and vine, then the structure can officially be called Wofatish. But it's not done, the next step is to begin working in some more soil into the ivy mat, and chucking all kinds of cool wet season growing seeds on it, and let grow what will.
It seems that if the building is only that size, and it is also edged with a total darkness thicket of sword ferns, pruning that Ivy patch once a year would pretty much be a cinch.
It'd be nice to have something sweet smelling or tasty or otherwise useful as a living surface right away, but English Ivy is the only A++ I know for the criteria of evergreen rain erosion control and vigorous climbing/root matting growth in marginal soil and water conditions.
Hope to start on this before too many months go by, but Operation Paddy Terrace and the rest of life are going to have to happen first haha.
