Some of the best use of space I’ve seen in a long time. Even though I’m blessed with almost one acre of land, a lot of it is taken up by play areas or swamp for half the season. The rest of the lawn is “harvested” for mulch. If I had the wood, I’d build at least one of these just to increase the yield in the sunnier parts of my garden.
The Hack: make a high-rise tiered garden to increase your useable space.
