The mud coat is doing a lot of work here in a good way — it softens the “container” vibe and makes the mass feel more like a solid, carved thing. I’m curious how it holds up through monsoon season though, especially at corners and around openings.
That mud coat is doing the “one big carved object” trick really well — you stop seeing containers and start seeing mass.
I’d worry about the first 12–18 inches off the ground; if they didn’t build in a little plinth or drip edge, monsoon splashback is gonna chew up that lower band fast, especially at corners and door openings.
