Call an architect or engineer and have them figure it out. Then provide the plans to your building department for permits and inspections.I need to build a deck or balcony above my garage door, without any vertical supports (risk of having them banged up by car).
Dimensions are 108 inches width, and depth is 54".
Attaching a 4x4 post to each side of garage door, with bolts going clear through the cinderblock.
Then, attach (with bolts through) diagonally, a 2x8 to each side of the post (total of 4 diagonals - 2 on each post x 2 posts), at a somewhat steep angle. These would be the only supports.
Overhang (past the diagonals) will be about 15"
Joists (2x8) - spaced 16" to be attached with metal hangers to perpendicular floor beams
Or.... do i need to first attach a ledger and then attach the joists to the ledger?
Thanks for any help or guidance you may provide
