This eco-friendly Swiss cluster of houses is quite the statement. The houses look like they belong in 'The Lord of the Rings,' what with their mounds of greenery and hidden appearance.
The underground houses are built around a lake and all feature green rooftops. There are approximately seven houses in the little cluster, all featuring various sizes. The biggest one is a seven-bedroom abode. This Swiss cluster of houses is charming and cute, not to mention great for the environment!
