I wonder if it's because people can't afford it?

Funny how there's fashion in gardens too. Everyone's garden seems the same here.

I used to stay in a horse lorry on an estate down in Dorset, and they had all this cool Victorian stone landscaping by the river. There was the most incredible structure there designed to echo the water that passed through the mill wheel. Otherworldly. They sure don't make stuff like they used to.
