there is a ton of space in the world, and a ton of desert outside of the spawn area, maybe try around the desert south of Coffee's place
Alternatively, the desert southeast of my lake - it'd be reasonably close to Sub's secondary community hub and it wouldn't be too close to anything else, except my lake base, in which case it'd blend it with a desert hill from my lake's perspective.
Or to the west or southwest of spawn - west would require tearing down/repurposing a village though. There's also plenty of land northeast of Onion's and some other assorted patches (some non-desert) if you don't mind going further out from spawn
