So the progress on the greenhouse has been slower than we’d hoped, but a baby will do that to your plans.
We have finished all the verticals and the header 2”x12”s. Here’s our handyman who is teaching me how to do this stuff properly (reducing the amount of “Let’s tear that out” I have to do).
We had a large number of windows from our neighbor and this was the first one installed. There will be solid 2x6 T&G siding below it, and then polycarbonate panel above/around it.
Here’s the current state as we head into the holidays:
That's 6"x6" pressure treated posts anchored in concrete and running about 10' to the top of the 2"x12" header. We've been doing everything with 3" deck screws meant for use in PT lumber.
