Ok, so I just got the attached plans back from my architect. She's never designed a deck before and is doing this for us as a favor, more than anything else.
So, does this work? Any major concerns or flaws?
Specifically, what do you think of how the pergola structure attaches to the deck? What sort of connector would you use? Would something like this work? http://www.strongtie.com/products/connectors/BC.asp
Where she calls for a 6x10, can I simply combine 4 2x10? Do they make a joist hanger large enough to support a 6x10?
My biggest concern is with the footers. The frost depth here is 30", so I know I need to go at least that deep, but what diameter should sonotube should I use?
