Today I finished the porch to the top right tatami room. Now all that is left is the railing around the outside of it, and the ovehang. I've already got the glass doors on the porch installed. I'll take a picture of that when I've finished the railings.
The porches and extensions take longer than the rooms inside. I suppose because there are so many steps to them. Only one more to go before I start on the roof!
