Nearly there! I had a stint off work last week, so got through the wall framing, and erected the rails also. The roof frame has been fabricated, but not sheeted yet.... of course it has rained all week!
Finally got a coat of paint on late this afternoon, of course with the cool conditions it still isn't touch dry (3 hours later!) - Here's hoping it remains clear tonight....
Hopefully will have a functional obs in a week or two.....
