WORLDS MOST SECRET HOMES S01E04

From secluded houses in forests and luxury bunkers buried underground to cabins on remote islands and homes hidden in mountains.

The series uses spectacular drone photography to explore the natural surroundings of each home and also ‘fly-through’ their interiors and secret passages to reveal what makes them unique.

We meet the owners who explain why they wanted to live in such an unusual property and how they found their secluded plots.

We reveal the innovative features that make each property unique – from pools hidden in cantilever rooftops, to mirrored sidings that help the structure blend in with its environment to homes that literally ‘fold-themselves away’ to hide from view.

Immersive CGI animation reveals how each property was built and its innovative use of materials and design.

This episode ventures to Buckinghamshire, England, where a striking modern home commissioned by Lord Rothschild has been built out of flint, an age-old material rarely used in construction today. In Switzerland we reveal a sleek glass residence nestled next to a scenic lake. In Sardinia we explore a stunning waterfront villa with its own secluded beach.
