OK, here comes the next major project on the garage: the car port/trellis/patio cover. I always planned to build a covered area off the front of my garage that looks like a trellis, but had a clear cover over the top to provide a dry area. It will overlap the roof on the rear porch of my house, thereby providing a covered area of my patio (for grilling in the rain), dry passage between the kitchen/backdoor of the house (primary entry and exit for us in practice) and the garage, and to the covered parking spot in front of the garage door for my wife. It will also double as an outside dry workspace for setting up the table saw and the like.
The driveway in front of the garage is not very wide, and I did not want to lose any useable area to a post to support the carport. I had originally planned on dropping a post on my property line next to my neighbor's garage (the yellow building) to support the carport structure. When I poured the new driveway I put a footing in for this use in the future. However, I have come to the conclusion I just could not spare the little bit of room in the driveway for such a post. It prevents any car parked there from being right up against the side of my neighbor's garage and thus allowing the most room possible on the driver's side (we back out a bit to let someone get in on the passenger side).
Thus I designed a steel structure with two columns that land on my concrete retaining wall and support a 19' long beam, half of which cantilevers out over the driveway. Then joists will attach to knees on the front of my garage, land on top of the beam, and cantilever out beyond the beam. Total covered area will be about 250 SF.
Here is the steel being installed. Note the north of the two columns will be seeing uplift forces due to the cantilever of the beam, so the column foot wraps around the side of the retaining wall to have two bolts anchor into the side. I had to pull up a section of the paving stone patio I laid down last year. It was a ***** to get the stones out, even using a 6' steel pry bar with my full weight on it. I done built it good!
