It's a sewer easement, so no house, but no-one's come to claim it. Personally I'd like a wildflower meadow but it'd require a significant investment in seeds I reckon, it's quite large. And it's also currently full of docks which won't take no for an answer I'd guess. I'm not sure I can afford that much round up!
