Since I'll be eventually be living only upstairs while I work on the downstairs and basement, I need a way to get in up there. I'd rather it be nice, so I just need to build a balcony off the master bedroom in the back. This roof next to the master bedroom is weird, so I'm just going to rebuild that along with it. First step is removing that asbestos siding I guess.
I decided to mark out where I want the supports to be and then start on plans for the framing and footings.
The vertical joists are for the balcony part, and the horizontal ones are for the roof next to it, and that continues back farther than the drawing shows.
I had one of my civil engineer friends help with the math for the column sizes, and this what we came up with at the beginning. It's built strong enough for high snow loads with minimal sinking into the ground over time. It'll probably be strong enough to park a car on, but its not really big enough to do that.
Now that's a lot of concrete bags, I ended up getting the 50lb ones since they cost about the same per bag as the 80lb bags but are easier to handle.
And some more marking to for scale, and it's nice to see this stuff more before digging.
