Adding on to what other's have already said, it's a great spot for machinery, trees, or just your own deco area as no npcs walk there (or even around it, you can place stuff safely all the way past the adventurer's guild).
It's also really close to the farm (in a practical sense), basically being the same effective distance as the town as you can just run up to the minecarts at the bus stop and instantly teleport there, so you can put stuff you want to use really often, without it being as far as other npc-empty places like south of cindersap which requires a long run through the farm and forest.
