Some beautiful sheds, here. I indeed debated the best plan for my own for several years, as I had some constraints:
1. I had been burning a lot of wood, and processing even more than I burned, to get ahead. I was stacking 13 - 15 cords per year, and burning roughly 10, until I got sufficiently ahead. This made me want a design where I could park a splitter or front-end loader right at the stacks for processing, and then later pull a trailer or large wagon directly up to the stacks to retrieve the wood, and eliminated any design where you have to walk deep into a shed to retrieve wood.
2. My township has a permitting requirement for any shed exceeding 100 sq.ft. If I could keep the footprint below 100 sq.ft., I would not require a site permit, and would not have to argue over proximity to wetlands, runoff studies, etc.
3. It had to look as nice as reasonably possible. We live in a neighborhood of larger lots (4 - 9 acres/ea), but still no one wants to look at a mess of metal roofing scraps in their neighbors yard, when the leaves drop from the trees that isolate us every winter.
A row of smaller wood "racks" (can't legally call them "sheds" < 100 sq.ft.) of precisely 96 sq.ft. and holding 4.0 cords each was my solution. Each rack has two bays on front and two bays on back, each bay being 2 rows deep (x18") for easy reach, each bay being exactly 1 cord for easy tracking of usage. They are all placed in a neat row, so I can simply park the splitter next to the bay I'm loading, and stack right off the log catcher. Later, I pull my 2-ton farm wagon along the row to the bay from which I am pulling, and load 'er up.
Although these photos were taken when I had only completed the first three, I presently have four of these racks (plus a smaller one-cord version on high ground), for only 17 cords of storage, about half of what I used to keep stacked on pallets. It's tight, I've got logs stacked everywhere just waiting to be processed, as I've whittled my storage down from the prior 30 cords. But I have a goal to cut back on how much wood I use, and also suspect my dry time will be less in these racks than on pallets, so I'm experimenting with this reduced storage volume before building more racks. The cost of the racks was almost exactly $1k/ea before COVID, but the one built in 2021 must have close pretty close to $2k.
