Rounded/curved room corners create stronger earthbag walls at no extra cost, and can speed construction. A good size radius is around 3’-4’ (about one meter). Rounded corners can also improve functionality by creating a cozy, curved space for a round table, computer desk, easy chair or, as in the photo above, a sofa. You could put a window, wood stove or fireplace in one of these curved corners. Other options include niches (nichos) and/or curved bookshelves. Rounded/curved room corners are very appealing visually and make a nice focal point. They break up the monotony of too many straight lines. Not every corner has to be rounded, of course. Even one rounded corner can improve the looks of your home. I think rounded corners look perfect with thick earthbag walls, especially when window and door openings are also curved.
