As a builder and Project Manager I give you a Not bad
We left a small gap between the tread and riser for water/snow drainage.
Not on the bottom two where the snow will be.......
I don't like the baluster details. I see them done this way all the time and I've always disliked them because the snow and leaves just collect and there's no where to shovel or sweep.
You used three posts on one girder and two posts with huge cantilevers on the the other one???? Did you forget a sonotube????
I don't like the deck being level to the inside floor system.
Rain and snow splash inside the door.
I sound like a jerk, huh?
I'm just pointing out details that you asked about.
If we all just say nice job and well done, you don't learn anything.
You did a great job on what you knew.
The rest is just details
You're a good friend and I commend your effort......nicely done.....
