Curved 2x10 nailers, cut on a band saw, define the exterior radius. We drew the curves with a string and a pencil, working right on the subfloor. A jigsaw blade we tried was too light-duty for the cuts, so we ended up making the curved rips on a band saw. We first attached 2x4 cleats to the 2x10 nailers, then nailed the cleats through the sheathing to the studs. To set off the curved bay from the main plane of the wall, we installed red cedar shingle siding with a shorter exposure than the cedar shingles on the rest of the house.
Sheet lead flashing over the window heads conformed easily to the curved jamb.
The architect proposed roofing the bay with a conical shingled roof or low-slope copper roofing, but the budget wouldn't allow it. More Email this article to a friend. All rights reserved.
