My hired carpenter took care of all the hard stuff, excavation for footers, demolition and establishing the deck framing
Meanwhile, I took care of the fine work, using timber framing joinery for the trellis cantilevers. The corner one was exceptionally difficult to lay out:
I decided to hang the bench footings off the posts using A34's but the legs are mortised into the rails in the usual way
Installation of the trellis on the deck was an exciting day, as the carpenter and myself combined our respective work to establish the whole. Since the posts were part of the deck structure, everything had to line up perfectly, and for the most part it did.
