We first spotted this unusual house many years ago. Back then it was quite new and the gardens had not been established, nor had the lawn. Over the years we've driven past occassionly, just for stickybeak value.
We've seen it develop into a spectacular building and garden then decline just a little into its current state. The "upstairs" lawn was lush and almost bowling-green smooth at one time but today it's in need of a bit of love and attention - an unfortunate casualty of the drought.
DO NOT APPROACH THE HOUSE. THE CACHE IS NOT THERE.
