The top and sides are already screwed together.  I have about one dozen bolts with washers to put in place, those holes have been made.
The description said the wood was pressure treated.  I think some of the wood needs a bit of sanding down.  I thought about treating it but then the plants might be affected by any residue.  So Instead, I will put it together and think about that next summer.
It looks like this when put together, but I opted to have  two "windows" at the top, so that the lids are not so heavy.

I have a lot of wooden planks in the garage.  I might learn how to do carpentry and make a second one, if needed, using that one as a prototype.
