Modern Metal Ponds

I'm on the lookout. I can't seem to find a local source for a metal garden pond, similar to these.

Ideally, it would be black or cor-ten steel. And of course it would need to be water-tight.

And I don't want a galvanized farm trough. Pointers, anyone?

Inspiring Houses: Dairy House

Check out the Dairy House by Charlotte Skene-Catling, which is a modern conversion of an early-20th century dairy in Somerset, England. In my opinion, nothing short of brilliant. And very inspiring.
