Personally, I was moved to comment when I read your position, because the FIRST thing I thought when I looked at the photo is the young gardener is SO fortunate to have this warm little recessed area on his hillside overlooking the chilly Pacific ocean! HA!
Yeah, if that was the PNW, he might even be able to squeeze out a melon or two and some peppers. To be fair, I would have done it different too, but it's not my yard. Of course now I'm thinking a little south facing wall to capture the heat, maybe a tall, semi-circular hugel-bed, I wonder if I could grow watermelons. Ok, back on track, you know that guy isn't going to stop there. If he doesn't give up on gardening altogether, that sparse square eventually isn't going to be enough. Pretty soon he's going to be either pulling up bits of concrete or building raised beds, or stacking pots in the corners, maybe growing hops along the walls. It's like an addiction. He will end up on permies, wondering how to make it all fit and work together...
