World's Most Secret Homes

This episode uncovers a 300-year-old Scottish ruin that's been brought back to life by an owner, who had the ingenious insight to build a unique modern home within its crumbling walls. In the Sierra Nevada mountain range, we discover a striking angular home built from zinc and glass to reflect the rugged landscape it sits in. In Sardinia, we explore a stunning waterfront villa with its own secluded beach. And in Germany, we reveal a wartime bunker that lay abandoned for 70 years, but has been given a new lease of life by a creative owner.
