Thread: A Japanese timber framed garden shed

Change of plans. A couple of friends who know Japanese architecture much better than I suggested a style that is nearly as simple but adds a few curves. I like these better, especially the second one. Time to get out the carving tools.

Shed's got wings, mostly. Three more rafters to go.

Barge boards are up. A friend came over today to help. Good thing because this really was a two person job. Trial fit, dismount it, some discrete joint surgery, and repeat until it fit. The first side took two and half hours working slowly with much head scratching and time up and down scaffolding. But we learned, and the second set took about 45 minutes. I'm happy with how it looks. Tight and solid with some gap not visible from below.

And rafters are up. Taped for coat of primer on the end grain.

One advantage of doing a small shed: I can cover the whole thing when it rains. This was our first real rain since early May. A nice all day drizzle. I was hoping to have the roof done by now but having the tarp takes some of the pressure off of finishing it.

I'm still working on the roof. It is slightly complicated. Sitting on the rafters are two perimeter frames. The lower one surrounds a set of ceiling boards and the upper one surrounds some plank decking. Furring strips sit on the ceiling boards and support the plank decking above. The upper frame is 15 mm wider than the lower frame all around to create a shadow line and also a drip line beyond the rafter ends. The frames are mitered at the corners and joined with a through and wedged tenon. There is a lapped joint at the ridge. And because I didn't have long enough stock to make the long arms of the frames of one piece I'm splice joining two shorter pieces. All of the joinery is slowing me down, but I'm having fun.

Here is a schematic of the roof structure minus any flashing. The surface cladding will be metal panels.

And the splice joint I'm using for the long arms of the frames. The arms of the frame will be screwed to the rafters to keep the rafters in line and prevent them from sagging.
