Hello, I have an existing deck that is only a year old that we would like to put a privacy wall up/wind block on the west side of the patio. I was thinking it would be about 6 feet tall or so and possibly made of cedar are my initial thoughts. The current deck is about 12x12’ and about 32 inches off the ground or so and I would only have this on west side. I live in ND and I is really windy in our area. Do I need to dig and pour footings for this or can I attach it to the existing structure and lag bolt it to the existing structure? Being 12 feet, how many posts 6 feet in the air do I need to have? Any tips in building one of these? Thanks

I'm planning to expand our deck possible to the corner of our home in the very near future. This will be my first deck project, so hoping to learn all I can first. The ledger will be attaching to the poured concrete foundation of the home. However, their is small 33" length casement basement window that the top half of the ledger will pass over when attaching to the house. I believe it is recommended to use expansion bolts to attach the Ledger correct? But I'm just concerned of having larger gap/space between these ledger bolts due to the window. Will I be with an ~33" spacing in the one section of the Ledger board? I can install them every 12 or 16" elsewhere, except in that area. There may be a small change I can add an expansion bolt to the bottom half of the ledger when it passed the window. I could as a last resort maybe drop the deck another 7" and add a 2nd step, but am hoping to avoid that .
